ABSTRACT

Abstract Background Interleukin-17 (IL-17) family plays a role in the pathogenesis of knee osteoarthritis (KOA) by contributing to the inflammatory and destructive processes in the affected joint. This study aimed to measure levels of IL-17 A and IL-25 (IL-17E) in serum of KOA patients and determine their roles in the disease severity of patients. Methods In this, 34 patients with KOA and 30 age and sex-matched healthy subjects (HS) were enrolled. Patients were categorized based on their Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Visual Analog Scale (VAS), and Body Mass Index (BMI) scores. The enzyme-linked immunosorbent assay (ELISA) technique was employed to measure serum levels of IL-17 A and IL-25. Results Level of IL-25 was significantly higher (P < 0.0001) in the KOA subjects than HS. IL-17 A level was significantly higher in KOA cases with WOMAC < 40 (P < 0.0001) in comparison to HS. IL-25 level was significantly higher in the KOA cases with WOMAC < 40 (P < 0.0001) and with WOMAC ≥ 40 (P < 0.0001) compared to HS. IL-17 A concentration was significantly higher in the KOA cases with VAS < 5 (P < 0.0001) compared to HS. IL-25 level was significantly higher in the KOA cases with VAS < 5 (P < 0.0001) and with VAS ≥ 5 (P < 0.0001) in comparison to HS. KOA patients with BMI ≥ 30 had significantly higher IL-17 A and IL-25 concentration in comparison to HS. Conclusions The serum level of IL-25 in KOA patients is increased probably due to negative controlling feedback on inflammatory responses, which can be associated with obesity and disease activity.

ABSTRACT

ObjectiveTo investigate the effects of Tongluo Juanbi granules on chondrocyte apoptosis and Toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-κB (NF-κB) signaling pathway of rabbits with knee osteoarthritis (KOA) and study the mechanism of Tongluo Juanbi granules in the prevention and treatment of KOA. MethodThirty New Zealand rabbits were randomly assigned to the following five groups (n=6): sham group, model group, low-dose and high-dose groups of Tongluo Juanbi granules (4.1 and 8.2 g·kg-1·d-1), and celecoxib group (10.9 mg·kg-1·d-1). The KOA model was established by destabilization of the medial meniscus (DMM) for six weeks. Six weeks after the modeling, the drug was given once a day for eight weeks. The pathological changes of cartilago articularis were observed by hematoxylin-eosin (HE) staining and Safranin O-Fast Green staining. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining was performed to detect chondrocyte apoptosis. Enzyme-linked immunosorbent assay (ELISA) was used to detect the contents of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in synovial fluid. The mRNA and protein expression levels of genes related to the TLR4/MyD88/NF-κB signaling pathway were detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. ResultCompared with the sham group, the cartilago articularis of the model group significantly degenerated. Mankin's score was increased (P<0.01), and the contents of IL-1β and TNF-α in synovial fluid were increased (P<0.01). The number of apoptosis of chondrocytes was increased (P<0.01). The mRNA and protein expressions of TLR4, MyD88, and NF-κB p65 in cartilage tissue were up-regulated (P<0.01), while the mRNA and protein expressions of Bcl-2 were down-regulated (P<0.01). Compared with the model group, chondrocyte degeneration in both low-dose and high-dose groups of Tongluo Juanbi granules was improved, and Mankin's score was decreased (P<0.01). The contents of IL-1β and TNF-α were decreased (P<0.01), and the number of apoptosis of chondrocytes was decreased (P<0.01). The mRNA and protein expressions of TLR4, MyD88, and NF-κB p65 in cartilage tissue were down-regulated (P<0.01), while the mRNA and protein expressions of Bcl-2 were up-regulated (P<0.01). In addition, in the above observation indicators, the high-dose group of Tongluo Juanbi granules was significantly superior to the low-dose group of Tongluo Juanbi granules. ConclusionTongluo Juanbi granules could inhibit chondrocyte apoptosis in rabbits with KOA and improve cartilage degeneration, which may be related to inhibiting inflammatory responses mediated by TLR4/MyD88/NF-κB signaling pathway.

ABSTRACT

@#Self-management education program (SMEP) is essential in the knee osteoarthritis (OA) management. While the benefits of tailored SMEP have been highlighted in the literature, evidence on the effects of tailored knee OA SMEP for multiethnic populations, such as in Malaysia, remains limited. Therefore, the aim of this study was to conduct an intervention study on a tailored SMEP among Malaysian older adults who aged 60 years and above with knee OA. Participants aged 60 years and over with a diagnosis of knee OA were recruited. The intervention comprised four weekly structured group SMEP which was developed specifically for the multicultural population in Malaysia. Symptom’s severity and functional performance were assessed at baseline and six-week follow-up using the Knee Injury and Osteoarthritis Outcome Score questionnaire (KOOS), 30 seconds sit to stand (30sST), time up and go (TUG), chair sit and reach (CSR), back stretch (BS), handgrip strength (HGS) and two-minute walk (2MW) tests. Of the 32 individuals recruited, 30 participants, mean age of 66.77 (±6.42) years, completed the post-intervention assessment. Improvements in mean KOOS domains scores were observed by between 1.3% - 8.6% from baseline to follow-up. Significant differences between baseline and followup scores were identified for 30sST (p < 0.05), TUG ( p < 0.001) and 2MW (p < 0.001) tests. A 4-week tailored SMEP delivered face to face by a physiotherapist, improved lower limb muscle strength, mobility, balance and endurance. Larger randomized controlled trials regarding the long-term effects of SMEP for older adults with OA is warranted.

ABSTRACT

OBJECTIVE To investigate the improvement effect and potential mechanism of “Layers adjusting external application” paste on synovial fibrosis (SF) in rats with knee osteoarthritis (KOA). METHODS Male SD rats were randomly divided into sham operation group, KOA group and Layers adjusting external application group, with 8 rats in each group. KOA model was induced by the anterior cruciate ligament disruption method in KOA group and Layers adjusting external application group. Fourteen days after modeling, the Layers adjusting external application group was given “Layers adjusting external application” paste [Sanse powder (8 g for every 100 cm2), Compound sanhuang ointment (5 g for every 100 cm2)] on the knee joint, 8 h every day, for 28 d in total. After the last administration, the degree of synovitis and fibrosis in rats was observed, and Krenn scoring was performed in each group. The expressions of collagen Ⅰ, high mobility group protein B1 (HMGB1) and phosphorylated nuclear factor-κB p65 (p-NF-κB p65) were detected in the synovial membrane; the contents of interleukin-1β (IL- 1β), IL-6 and tumor necrosis factor-α (TNF-α) in serum as well as the expressions of fibrosis-related and HMGB1/Toll-like receptor 4 (TLR4)/NF-κB signaling pathway-related proteins and mRNA were detected in synovial tissue. RESULTS Compared with the sham operation group, the synovial lining cells in the KOA group showed significant proliferation and disordered arrangement, the inflammatory cell infiltration and collagen fiber deposition were obvious; the positive expressing cells of collagen Ⅰ, HMGB1 and p-NF-κB p65 were increased significantly; the contents of IL-1β, IL-6 and TNF-α in serum, the expressions of fibrosis-related protein (transforming growth factor-β, collagen Ⅰ, tissue inhibitor of metalloproteinase 1, α-smooth muscle actin) and their mRNA as well as theexpressions of HMGB1, TLR4 protein and their mRNA, the expressions of p-NF-κB p65 protein and NF-κB p65 mRNA were all increased significantly in synovial tissues of rats (P<0.01). Compared with the KOA group, the pathological changes in the synovial tissue of rats in Layers adjusting external application group were significantly improved, and the above quantitative indicators were significantly reversed (P<0.05 or P<0.01). CONCLUSIONS “Layers adjusting external application” paste could significantly improve SF in KOA rats, the mechanism of which may be associated with the inhibition of the activation of HMGB1/ TLR4/NF-κB signaling pathway.

ABSTRACT

OBJECTIVE@#To explore effect of nerve growth factor (NGF) antibody on knee osteoarthritis (KOA) pain model was evaluated by in vitro model.@*METHODS@#Thirty male SPF rats aged 28-week-old were divided into blank group (10 rats with anesthesia only). The other 20 rats were with monoiodoacetate (MIA) on the right knee joint to establish pain model of OA, and were randomly divided into control group (injected intraperitoneal injection of normal saline) and treatment group (injected anti-NGF) intraperitoneal after successful modeling, and 10 rats in each group. All rats were received retrograde injection of fluorogold (FG) into the right knee joint. Gait was assessed using catwalk gait analysis system before treatment, 1 and 2 weeks after treatment. Three weeks after treatment, right dorsal root ganglia (DRG) were excised on L4-L6 level, immunostained for calcitonin gene-related peptide (CGRP), and the number of DRGS was counted.@*RESULTS@#In terms of gait analysis using cat track system, duty cycle, swing speed and print area ratio in control and treatment group were significantly reduced compared with blank group (P<0.05). Compared with control group, duty cycle and swing speed of treatment group were significantly improved (P<0.05), and there was no significant difference in print area ratio between treatment group and blank group (P>0.05). The number of FG-labeled DRG neurons in control group was significantly higher than that in treatment group and blank group (P<0.05). The expression of CGRP in control group was up-regulated, and differences were statistically significant compared with treatment group (P<0.05).@*CONCLUSION@#Intraperitoneal injection of anti-NGF antibody inhibited gait injury and upregulation of CGRP in DRG neurons. The results suggest that anti-nerve growth factor therapy may be of value in treating knee pain. NGF may be an important target for the treatment of knee OA pain.

ABSTRACT

SUMMARY OBJECTIVE: Pathology in any segment of the spine-pelvis-lower extremity may impair the global postural balance, leading to compensatory alterations in other parts. The aim of this study was to compare the pelvic movements of patients suffering from knee osteoarthritis with patients who underwent total knee arthroplasty and healthy controls. METHODS: This study was performed at the Department of Orthopedics and Traumatology Clinic of a Cankiri State Hospital between April 2021 and February 2022. This study included 84 participants. Of them, 31 patients who underwent total knee arthroplasty between 2018 and 2020 years were selected as the total knee arthroplasty group, while 28 patients with knee osteoarthritis were selected as the knee osteoarthritis group. In the control group, there were 25 healthy individuals. Exclusion criteria from the study included any kind of neurological disease, an inability to walk a distance of 100 m unassisted, or a history of surgery to the lower limb. Pelvic movements (i.e., tilt, rotation, and obliquity) and gait parameters (i.e., "gait velocity," "cadence," and "stride length") were assessed using a wireless tri-axial accelerometer. RESULTS: Total knee arthroplasty and control groups had decreased minimum anterior tilt of the pelvis, decreased maximum anterior tilt, and decreased oblique range of the pelvis compared with the knee osteoarthritis group. In comparison with the control group, gait velocity and length of stride during gait were remarkably lower in both knee osteoarthritis and total knee arthroplasty groups. CONCLUSION: In this study, total knee arthroplasty was found to affect pelvic movements. It was thought that total knee arthroplasty changed these variables, probably owing to the frontal and sagittal plane alignment correction through surgery.

ABSTRACT

ABSTRACT BACKGROUND AND OBJECTIVES: Individuals with osteoarthritis (OA) often have joint pain and are overweight or obese. Thus, the objective of this study was to observe whether there is correlation between body mass index and joint pain intensity with gait performance in individuals with OA. METHODS: Cross-sectional study, which evaluated 60 volunteers, being 30 with clinical diagnosis of knee osteoarthritis and 30 without the disease, of both sexes and aged between 50-82 years. Joint pain intensity was assessed using the Visual Analog Scale, gait-related functional tasks using the Dynamic Gait Index, and the functional mobility using the Timed Up and Go test. RESULTS: There was a correlation between overweight/obesity and high levels of joint pain intensity (p=0.018), with worse performance in gait-related functional tasks (p=0.000) and with worse functional mobility (p=0.034) only for the individuals with OA. High levels of joint pain intensity also correlated with worse performance in the gait-related functional tasks (p=0.000) in the OA group, and also with worse functional mobility in the OA group (p=0.001) and also in the group of individuals without the disease (p=0.032). CONCLUSION: This study identified a correlation between overweight/obesity and high levels of joint pain intensity and worse gait performance in individuals with osteoarthritis. High levels of pain intensity also correlated with worse gait performance in individuals with OA.


resumo JUSTIFICATIVA E OBJETIVOS: Indivíduos com osteoartrite (OA) frequentemente apresentam dor articular e sobrepeso ou obesidade. Assim, o objetivo deste estudo foi observar se existe correlação entre o índice de massa corporal e a intensidade da dor articular com o desempenho da marcha em indivíduos com OA. MÉTODOS: Estudo de corte transversal, que avaliou 60 indivíduos, sendo 30 com diagnóstico clínico de osteoartrite de joelho e 30 sem a doença, de ambos os sexos e com faixa etária entre 50 e 82 anos. A intensidade da dor articular foi avaliada pela Escala Analógica Visual, as tarefas funcionais relacionadas à marcha pelo Dynamic Gait Index e a mobilidade funcional pelo teste Timed Up and Go. RESULTADOS: Houve correlação entre o sobrepeso/obesidade e níveis elevados de intensidade da dor articular (p=0,018), com um pior desempenho nas tarefas funcionais relacionadas à marcha (p=0,000) e com menor mobilidade funcional (p=0,034) apenas para os indivíduos com OA. Os níveis elevados de intensidade de dor articular também mostraram correlação com um pior desempenho nas tarefas funcionais relacionadas à marcha (p=0,000) no grupo com OA, e ainda, com uma menor mobilidade funcional no grupo com OA (p=0,001) e também no grupo de indivíduos sem a doença (p=0,032). CONCLUSÃO: Este estudo identificou correlação entre o sobrepeso/obesidade com níveis elevados de intensidade da dor articular e com um pior desempenho na marcha nos indivíduos com OA. Os elevados níveis de intensidade da dor também mostraram correlação com pior desempenho na marcha nos indivíduos com OA.

ABSTRACT

Introducción La artrosis de rodilla es una patología que afecta la calidad de vida, siendo la artroplastía de rodilla un tratamiento costo-efectivo para la etapa severa de esta enfermedad. El acceso a artroplastia de rodilla es un indicador de salud de la Organización de Cooperación y Desarrollo Económico. Los objetivos de este estudio son determinar la incidencia de artroplastia de rodilla entre 2004 y 2021 en los beneficiarios del Fondo Nacional de Salud en Chile, la proporción que se operaron en el sistema privado y estimar el gasto del bolsillo del paciente para operarse. Método Estudio transversal. Se utilizó la base de datos del Departamento de Estadística e Información de Salud. Se pesquisaron pacientes que egresaron de un centro de salud chileno que fueron intervenidos por artroplastia rodilla entre 2004 y 2021. Se analizó la proporción de pacientes por tramo del Fondo Nacional de Salud y si se realizó su cirugía en establecimiento de la red pública o privada. Resultados De las 31 526 intervenciones de artroplastia de rodilla, 21 248 (67,38%) fueron realizadas en pacientes del Fondo Nacional de Salud y 16 238 en instituciones públicas (51,49%). Los pacientes de dicho fondo presentan un alza sistemática en el volumen de artroplastías de rodilla hasta 2019, pero disminuyeron en 2020 y 2021 un 68% y un 51%. Del total de pacientes del sistema público operados de artroplastia de rodilla, 856 (9%) pertenecían al tramo A1, al tramo B 12 806 (60%), al tramo C 2044 (10%) y al tramo D 4421 (21%). Se estimó que el gasto incurrido por estos pacientes varía entre el 24,4 y 27,2%. Las proporciones históricas de acceso en instituciones privadas a esta cirugía son en el tramo A 7%, tramo B 13%, tramo C 24% y tramo D 52%. Conclusión El 50% de las cirugías de artroplastía de rodilla se realizan en instituciones públicas y dos tercios se realizan en pacientes del Fondo Nacional de Salud. El 46% de los tramos C y D se operaron en el sistema privado. La pandemia ha aumentado la brecha de acceso, lo que ha provocado un alza significativa en la proporción de pacientes del Fondo Nacional de Salud de los tramos B, C y D que han migrado al sistema privado para acceder a esta cirugía.


Introduction Knee osteoarthritis affects the quality of life, with knee arthroplasty being a cost-effective treatment for the severe stage of this disease. Access to knee arthroplasty is a health indicator of the Organisation for Economic Co-operation and Development. The objectives of this study are to determine the incidence of knee arthroplasty between 2004 and 2021 in beneficiaries of the National Health Fund in Chile, the proportion of patients who underwent surgery in the private system, and to estimate the patient's out-of-pocket expenditure for surgery. Methods Cross-sectional study. We used the Department of Statistics and Health Information database. Patients discharged from a Chilean health center who underwent knee arthroplasty surgery between 2004 and 2021 were investigated. We analyzed the proportion of patients by their National Health Fund category and whether their surgery was performed in public or private network facilities. Results Of the 31 526 knee arthroplasty procedures, 21 248 (67.38%) were performed on National Health Fund patients and 16 238 in public institutions (51.49%). Patients from the National Health Fund showed a systematic increase in knee arthroplasty volume until 2019 but decreased in 2020 and 2021 by 68% and 51%. Of the total number of patients in the public system operated on for knee arthroplasty, 856 (9%) belonged to group A1, 12 806 (60%) to group B, 2044 (10%) to group C, and 4421 (21%) to group D. The expenditure incurred by these patients was estimated to vary between 24.4% and 27.2%. The historical proportions of access to this surgery in private institutions are 7% in group A, 13% in group B, 24% in group C, and 52% in group D. Conclusion Fifty percent of knee arthroplasty surgeries are performed in public institutions, and two-thirds are performed on patients of the National Health Fund. Forty-six percent of the C and D groups were operated in the private system. The pandemic has increased the access gap, leading to a substantial increase in the proportion of patients from the National Health Fund of the B, C, and D groups who have migrated to the private system to access this surgery.

ABSTRACT

Obesity is an important risk factor related to osteoarthritis, but it′s role in post-traumatic osteoarthritis on young people need to further study. The internal mechanism except the mechanical loading may be associated with adipose exosomes. To examine the effect of obesity induced by high fat diet and adipose exosomes on knee post-traumatic osteoarthritis caused by destabilization of medial meniscus (DMM) surgery in young mice, 20 6-week-old C57BL/6J mice were randomly assigned to the control diet group (CD, n = 5), the DMM group (n = 5), the high fat diet group (HFD, n = 5) and the HFD plus DMM group (HFD+DMM, n = 5). The CD and DMM group were fed with a control diet, and the HFD and HFD+DMM group were fed with a high fat diet. We did the DMM surgery and the sham surgery on the mice when it was 10 weeks old. Extract obese and normal adipose exosomes, identify exosomes in vitro, and proceed fluorescence imaging in vivo using DiR staining. DMM+HFD-Exo group and DMM+CD-Exo group were injected the exosomes from the tail vain once a week (100 μL per shot with a concentration of 1 μg·μL-1). Second, 15 6-week-old C57BL/6J mice were randomly assigned to the DMM group (n = 5), the DMM plus obese adipose exosomes group (DMM+HFD-Exo, n = 5), and the DMM plus control diet adipose exosomes group (DMM+CD-Exo, n = 5). Animal welfare and experimental process are in accordance with the regulations of the Experimental Animal Ethics Committee of Nanjing University (IACUC-D2204005). All mice were sacrificed at the age of 18 weeks, the knee joints of the mice were harvested and fixed. We used micro CT to examine the samples and measured the bone volume/tissue volume, trabecular thickness, trabecular number and trabecular separation. Then the samples were decalcified and embedded in paraffin, and 4 μm thickness sections were stained with H&E and safranin O/fast green to observe the histological changes of the knee joint. The results showed compared with the control diet group, high fat diet induced obesity can aggravate the pathological changes of the post-traumatic osteoarthritis caused by DMM surgery, which shows in having a higher Mankin score. The surface of knee articular cartilage in the HFD+DMM group was rough, and the subchondral bone has an increase in bone sclerosis. Compared with the DMM group, obese adipose exosomes can exacerbate the pathological changes of the knee articular cartilage, while not influencing the subchondral bone. In conclusion, high fat diet induced obesity can aggravate the post-traumatic osteoarthritis caused by DMM surgery in young mice. The obese adipose exosomes mainly affect the surface of the knee articular cartilage.

ABSTRACT

ObjectiveTo evaluate the inter-rater and test-retest reliability of echo intensity of ultrasound image for quality of quadriceps femoris in patients with knee osteoarthritis (KOA). MethodsFrom March to December, 2021, 33 patients with unilateral KOA in Guangdong Provincial Second Hospital of Traditional Chinese Medicine were included. Ultrasound was used to observe the cross sections of rectus femoris (RF), vastus medialis (VM) and vastus lateralis (VL), and the images were saved. Two independent raters analyzed the average gray value of the picture with the Image J. One of the raters repeated the measurement. The intra-class correlation coefficient (ICC), standard error of measurement (SEM), minimum detectable change (MDC) and coefficient of variation (CV) were calculated and the Bland-Altman charts were drawn. ResultsThe gray value was higher in the RF, VM and VL in the affected side than in the healthy side (t > 2.262, P < 0.05). The inter-rater reliability was excellent, with ICC 0.982 to 0.995, SEM 1.60 to 3.82, CV 1.49% to 5.90%, and MDC value 4.43 to 10.59. The test-retest reliability of the rater was excellent, with ICC 0.969 to 0.990, SEM 2.37 to 5.41, CV 2.22% to 4.84%, and MDC value 6.57 to 15.00. Bland-Altman charts analysis showed that the consistency was good. ConclusionThe quadriceps femoris muscle quality is different between the affected and the healthy sides in patients with unilateral KOA. It is reliable to evaluate muscle echo intensity by Image J.

ABSTRACT

ObjectiveTo compare the effect of proprioceptive neuromuscular training methods on pain and motor ability of knee in patients with early knee osteoarthritis (KOA) . MethodsFrom November, 2022 to May, 2023, 60 early KOA patients from Beijing Bo'ai Hospital and community were randomly divided into groups A, B and C, with 20 patients in each group. Group A received proprioceptive neuromuscular facilitation (PNF), group B received neuromuscular exercise (NEMEX), and group C received PNF and NEMEX, for six weeks. They were assessed with Visual Analogue Scale for pain (VAS), angle reappearance test, difference of pre-motor reaction time (VM-VL), active range of motion (AROM) of knee flexion, 10-meter walk test (10MWT), and Knee Injury and Osteoarthritis Outcome Score (KOOS) before and after treatment. ResultsAll the indexes improved in all the groups after treatment (|t| > 2.532, P < 0.05). Among the groups, the VAS score was the least in group A, and then groups C and B; the angle reappearance error was the least in group C, and similar in groups A and B; the VM-VL was the least in groups A and C, followed by group B. ConclusionPNF, NEMEX and PNF+NEMEX can relieve the pain and improve the motor function of knee in patients with early KOA, however, PNF is the most effective on relieving pain, and PNF+NEMEX is the most effective on improving knee function.

ABSTRACT

Knee osteoarthritis (KOA) is a common degenerative joint disease in the middle-aged and elderly. The incidence of KOA is rising as the population aging aggravates and the obese population grows. KOA seriously affects the health and daily life of the patients. The commonly used drugs for the symptomatic treatment of KOA include non-steroidal anti-inflammatory drugs, cartilage protective drugs, and opioid analgesics, which have limited therapeutic effects and induce obvious adverse drug reactions. Eucommiae Cortex is one of the commonly used Chinese herbal medicines for the treatment of KOA, while its pharmacological material basis and mechanism remain unclear, which limits its clinical application. The active ingredients of Eucommiae Cortex for treating KOA mainly include iridoids (geniposide, aucubin), lignans (pinoresinol diglucoside), flavonoids (quercetin, astragaloside, baicalein, hyperoside, and kaempferol), phenylpropanoids (chlorogenic acid), and polysaccharides. These compounds regulate the levels of inflammatory cytokines, inhibit oxidative stress, protect chondrocytes, balance the synthesis and degradation of extracellular matrix, and control the progression of KOA via the mitogen-activated protein kinase, nuclear factor-κB, phosphatidylinositol-3-kinase/protein kinase B, and Janus kinase 1/signal transducer and activator of transcription 3 signaling pathways. This paper introduces the mechanisms of Eucommiae Cortex and its active components in the treatment of KOA, aiming to provide a theoretical basis for the development of new drugs for KOA.

ABSTRACT

ObjectiveTo explore the clinical efficacy of Osteoking combined with non-steroidal anti-inflammatory drugs in the treatment of knee osteoarthritis based on real-world data and provide a basis for clinical medication. MethodFrom May 2020 to December 2021, the data of a total of 1 002 patients with knee osteoarthritis who did not undergo knee joint replacement surgery was collected through the registration method. 952 patients were ultimately included, including 133 cases orally taking Osteoking combined with non-steroidal anti-inflammatory drugs as the observation group and 73 cases orally taking non-steroidal anti-inflammatory drugs alone as the control group. Statistical analysis was conducted on the baseline data, VAS scores, WOMAC scores, and other items. The visit point is the 4th and 8th weeks after registration. In order to further elucidate the clinical efficacy of Osteoking combined with non-steroidal anti-inflammatory drugs in the treatment of knee osteoarthritis, the effective components of Osteoking and the relevant gene sets of non-steroidal anti-inflammatory drugs and knee osteoarthritis were obtained through network pharmacology methods and retrieval in bone injury cross database, TCMSP, and other databases. Venn analysis was performed on the relevant gene sets, and a PPI network diagram was constructed. Then key core targets were screened out, and enrichment GO and KEGG enrichment analyses were conducted. ResultThe VAS score of the observation group decreases by an average of (-2.79±1.206) scores in the 4th week, which is better than the control group [(-2.73±1.575) scores, P<0.05]. The VAS score of the observation group decreases by an average of (-3.97±1.308) scores in the 8th week, which is better than the control group [(-3.89±1.822) scores, P<0.05]. The total WOMAC score of the observation group decreases by an average of (-52.07±21.677) scores points in the 8th week, which is significantly better than the control group [(-46.75±25.368) scores, P<0.05]. The observation group has an average decrease of (-10.99±4.229) scores in WOMAC (pain) score in the 8th week, which is better than the control group [(-10.03±5.535) scores, P<0.05]. The observation group has an average decrease of (-1.49±2.901) in WOMAC (stiffness) score in the 4th week, which is better than the control group [(-0.92±1.998) scores, P<0.05], and the observation group has an average decrease of (-1.90±3.200) scores in WOMAC (stiffness) score in the 8th week, which is better than the control group [(-1.26±2.230) scores, P<0.05]. The observation group shows an average decrease of (-39.17±16.562) scores in WOMAC (joint function) score in the 8th week, which is significantly better than the control group [(-35.47±20.098) scores, P<0.05]. According to network pharmacology analysis, the core network target of Osteoking in treating knee osteoarthritis is manifested as regulating signal pathways such as signal transduction transcription activator 3(STAT3), vascular endothelial growth factor A(VEGFA), tumor necrosis factor (TNF) to regulate cell signaling, angiogenesis, chondrocyte proliferation and migration, and inflammatory cells, thereby inhibiting inflammatory reactions, reducing damage, and delaying the development of the disease. ConclusionAfter a 4-week and 8-week course of treatment for knee osteoarthritis with Osteoking combined with non-steroidal anti-inflammatory drugs, there is a significant therapeutic effect on relieving pain and joint stiffness and improving joint function. In network pharmacology, Osteoking is involved in regulating inflammatory factors, metabolic response-related biological processes, the proliferation and apoptosis of chondrocytes, etc. in the treatment of knee osteoarthritis, resulting in anti-inflammatory and analgesic effects and improving joint mobility and joint stiffness. Therefore, it is worthy of clinical promotion and application.

ABSTRACT

ObjectiveTo investigate the improvement of the efficacy of Osteoking in patients with knee osteoarthritis in the onset and remission stage and to systematically explore its potential intervention mechanism, so as to provide a certain reference for improving the clinical application value of Osteoking and guiding its clinical rational drug use. MethodThrough the real-world study of the treatment of knee osteoarthritis with Osteoking, the data was obtained and entered into the "Osteoking for the treatment of knee osteoarthritis case registration system", and 105 patients with episodic and remission knee osteoarthritis from the outpatient or inpatient orthopedic department of 20 medical institutions, including the Third Affiliated Hospital of Beijing University of Chinese Medicine, Peking Union Medical College Hospital, Wangjing Hospital of the Chinese Academy of Chinese Medical Sciences and Hunan Aerospace Hospital, from May 1, 2020 to December 31, 2021, were selected in the system. It included 60 patients treated with Osteoking and joint injection, and 45 patients treated with joint injection alone. The WOMAC osteoarthritis index score, visual analogue (VAS) pain score, individual types of pain symptoms (cold pain, hot pain, tingling, dull pain, soreness) and other TCM symptoms were observed and compared between the two groups, and statistically analyzed. In order to further elucidate the potential molecular mechanism of Osteoking combined with joint injection in the treatment of knee osteoarthritis in the treatment of onset and remission, this study used the "Bone Injury Cross Database (http://bone-xtrans.com/database,BX-Data)" to collect the gene set of knee osteoarthritis disease, the traditional Chinese medicinal materials, chemical composition, material base, candidate target, candidate target, sodium hyaluronate candidate target data for screening, and constructed an interaction network of "disease target". ResultsAmong the 105 patients with knee osteoarthritis enrolled, 15.24% (16/105) were in the episodic period, 84.76% (89/105) were in remission, and there were no convalescent patients. There were 72 cases (68.57%) in women, 33 cases (31.43%) more than men, 60 cases in the observation group and 45 cases in the control group in 105 patients. There were 20 patients with a VAS score of 5 and 19 patients with a score of 6 in the observation group, accounting for 65.00% of the observation group. The comparative results of VAS scores between groups before and after treatment showed that the scores of the two groups were (4.42±1.01) scores, (5.00±1.02) scores.4 weeks after treatment, and (3.12±1.04) scores and (3.56±1.08) scores,8 weeks after treatment, respectively, which were lower than those before treatment (6.23±1.28) scores,( 6.02±1.22) scores (P<0.05), and the comparative results of the pain properties of the two groups showed that the improvement rates before and after thermal pain and tingling in the observation group were 3.3%(2/60) and 16.7%(10/60), respectively. The control group was 2.2% (1/45)and 15.6%(7/45)[(χ2=4.034、13.583,P<0.05)], respectively, and the improvement rate of cold pain and soreness in the observation group was 5.0%(3/60) and 3.3%(2/60), which was higher than that of the control group . The results of comparing the WOMAC scores before and after treatment of the two groups showed that the difference between the stiffness score before and after treatment in the observation group was (1.68±1.42) scores, the difference between the score before and after treatment in the control group was (1.20±1.60) scores (P<0.05), and the pain score before and after treatment was (3.43±2.88) scores, the difference before and after daily activity score was (12.37±10.21) scores, and the total score before and after treatment was (17.48±12.76) scores, which were also higher than those in the control group (2.82±3.29), (10.80±9.63),(14.82±12.62) scores. The results of comparing the improvement of other symptoms before and after treatment showed that the improvement rate of less sleep and more dreams in the observation group was 28.3%(17/60), which was significantly higher than that of the control group of 2.2%(1/45)(χ2=5.914,P<0.05), and the improvement rates of the five symptoms of thirst and drinking, irritability, dry mouth and pharynx, dull complexion and hand, foot and mouth fever in the observation group were 3.3%(2/60), 10.0%(6/60), 8.3%(5/60), 10.0%(6/60) and 5.0%(3/60), respectively, which were higher than those in the control group -2.2%(1/45), 2.2%(1/45), 2.2%(1/45), 4.5%(2/45), -6.7%(3/45). Through network analysis, it was found that the enrichment pathway of Henggu bone wound healing agent mainly acted on the three mechanisms of bone improvement, energy metabolism and anti-inflammatory and analgesic, and the sodium hyaluronate enrichment pathway mainly acted on the anti-inflammatory and analgesic mechanism. ConclusionThe efficacy of Osteoking combined with intra-articular injection of sodium hyaluronate in the treatment of patients with knee osteoarthritis in attack and remission is better than that of sodium hyaluronate alone, especially in anti-inflammatory and analgesic, and the two drugs have synergistic effect. Osteoking may play its role in relieving the symptoms of joint stiffness, tingling, heat pain, and less sleep and more dreams by improving bone quality and regulating the body's energy metabolism pathways, which is worthy of clinical promotion.

ABSTRACT

ObjectiveTo investigate the clinical efficacy and mechanisms of Osteoking in the treatment of knee osteoarthritis (KOA) in real-world practice, so as to provide a basis for the rational clinical use of Osteoking. MethodFrom the Osteoking for knee osteoarthritis case registration system, 638 KOA cases treated with Osteoking were selected and analyzed in SPSS 26.0. The clinical data were collected from 20 hospitals in China from May 2020 to December 2021. Descriptive analyses of patient age, gender, body mass index, course of treatment and other parameters were performed. The Mann-Whitney U test was performed to compare the visual analogue scale (VAS) and Western Ontario and McMaster universities arthritis index (WOMAC) scores before and after treatment. The integrative pharmacology-based research platform of traditional Chinese medicine (TCMIP) v2.0 was used for network analysis of the core targets of Osteoking in treating knee osteoarthritis. Furthermore, 20 KOA patients treated with Osteoking in the Third Affiliated Hospital of Beijing University of Chinese Medicine from October to December in 2022 were enrolled in the treatment group, and 20 healthy volunteers in the control group. The enzyme-linked immunosorbent assay was employed to measure the serum levels of related indicators to verify the prediction results. ResultA total of 638 KOA patients were treated with Osteoking, including 429 (67.24%) receiving Osteoking alone and 209 (32.76%) receiving Osteoking combined with other therapies. The female patients (415, 65.05%) were more than the male patients (223, 34.95%). The patients showed the mean age of (63.48±13.51) years, mean body mass index of (24.09±2.98) kg·m-2, and mean course of treatment of (15.78±9.66) days. Most of the patients were rated as grades Ⅱ (46.24%) and Ⅲ (34.64%) in Kellgren-Lawrence (K-L) grading and in the relief stage (82.45%) in clinical staging. There was no significant correlation between clinical staging and K-L grading results. The cluster analysis identified three TCM syndromes: Qi stagnation and blood stasis, cold-dampness obstruction, and liver-kidney deficiency. The overall clinical efficacy evaluation showed that VAS score decreased from (6.01±0.85) scores before treatment to (2.54±1.73) scores after treatment (P<0.05), and the WOMAC score decreased from (93.25±25.91) scores before treatment to (50.73±25.14) scores after treatment (P<0.05). The network analysis predicted that Osteoking might regulate the transforming growth factor-beta (TGF-β), tumor necrosis factor-alpha (TNF-α), and nuclear factor-kappa B (NF-κB) signaling pathways to exert the therapeutic effect. The clinical trial showed elevated TGF-β1 level (P<0.01) and lowered NF-κB subunit RELA and tumor necrosis factor receptor superfamily, member 1A (TNFRSF1A) levels (P<0.05) after treatment. The synergistic effects of these changes provide a multidimensional and comprehensive therapeutic efficacy for KOA, alleviating the joint pain and limited mobility in patients. ConclusionOsteoking showed significant therapeutic efficacy in treating KOA. Osteoking may act on multiple pathways involved in cartilage metabolism and inflammation. The findings provide experimental evidence and theoretical support for elucidating the multi-target mechanism of Osteoking in treating KOA.

ABSTRACT

SUMMARY OBJECTIVE: Therapeutic exercises are well documented for the treatment of osteoarthritis; there is less evidence on what the effect of closed kinetic chain exercises is for knee osteoarthritis. The aim of this study was to investigate the effects of open kinetic chain exercises and closed kinetic chain exercises on pain, muscle strength, functional status, and quality of life in patients with knee osteoarthritis. METHODS: The study included a total of 60 patients with primary unilateral knee osteoarthritis grade I and II. The patients were categorized into three groups as open kinetic chain exercises (n=20), closed kinetic chain exercises (n=20), and control group (n=20). The outcome measures, including pain, isokinetic muscle strength, functional status, and quality of life, were collected at baseline and at the end of 6 and 12 weeks. RESULTS: Closed kinetic chain exercises and open kinetic chain exercises had significant improvement in pain, muscle strength, WOMAC, and SF-36 scores after the treatment and at their 6th and 12th week follow-ups compared to their baseline values and compared to the control group (p<0.05). CONCLUSION: The changes in all outcome measures were similar between closed kinetic chain exercises and open kinetic chain exercises (p>0.05). Closed kinetic chain exercises and open kinetic chain exercises were similar for knee osteoarthritis grade I and II. Closed kinetic chain exercises could be safely added to the exercise programs of patients with low-grade knee osteoarthritis.

ABSTRACT

Abstract Objective: With the aging of the population, more patients have complained of pain due to knee Osteoarthritis (OA), and the number of arthroplasties has also increased. The objective of this study is to evaluate the prevalence of the neuropathic pain component in candidates for Total Knee Replacement and the effects of this component on their quality of life. Methods: In this cross-sectional study, patients with OA candidates for knee arthroplasty in the present institution were evaluated using the pain detection questionnaire and the Visual Analog Pain (VAS) scale to measure the pain index and the presence of associated neuropathic pain. In addition, evaluation of the quality of life and functionality using the EQ5D and SF12 questionnaires and their relationship with cases of neuropathic pain were performed. Results: One hundred twenty-six patients were evaluated, and 71.4 % were female. The age ranged from 46 to 85 years, and about 70 % of the patients had some associated clinical comorbidity. Neuropathic pain was present in 28.6 % of the patients evaluated. Patients with neuropathic pain presented worse results in the VAS evaluation, in the care, pain, and anxiety domains of the EQ5D, and in the physical and mental scores of the SF12. Conclusion: Neuropathic pain was present in 28.6 % of the patients with knee OA who are candidates for arthro-plasty. Patients with associated neuropathic pain present a higher level of pain and worse quality of life scores. Recognizing this type of pathology is extremely important in fully monitoring gonarthrosis.

ABSTRACT

As the research of traditional Chinese medicine (TCM) on knee osteoarthritis (KOA) is progressing, researchers have discovered that a variety of Chinese medicines can delay the progress of KOA by regulating signaling pathways at the molecular level. The Chinese medicines and their active ingredients mentioned in this article are associated with the signaling pathways in KOA. They can regulate the levels of targeted molecules via different signaling pathways to inhibit cartilage inflammatory cytokine, apoptosis, and cartilage matrix degradation and promote chondrocyte autophagy, so as to reduce the synovial inflammatory edema and delay cartilage degeneration. This paper systematically reviews the studies about the TCM intervention of KOA. Baicalein can reduce the inflammatory cytokines and apoptosis and promote the autophagy of chondrocytes by blocking the phosphatidylinositol-3 kinase/protein kinase (PI3K/Akt) signaling pathway. Cornuside I can decrease the phosphorylation activity of Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) pathway to reduce synovial inflammation and delay cartilage matrix degeneration. Salvianolic acid A can reduce inflammation and cartilage matrix degradation by inhibiting the phosphorylation of the nuclear factor-κB (NF-κB) pathway. Emodin can reduce the activity of Wnt/β-catenin pathway to inhibit the decomposition of collagen and proteoglycan. Myristicoside can inhibit apoptosis by blocking the p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway. Akebia saponin D can enhance the activity of nuclear factor E2-related factor 2/heme oxygenase 1(Nrf2/HO-1) pathway to inhibit oxidative stress in chondrocytes. The saponins in Achyranthis Bidentatae Radix reduce cartilage matrix degradation by enhancing the transforming growth factor-β (TGF-β)/Smad signaling pathway. Crocin inhibits the cartilage inflammation and apoptosis factor increase by stimulating the activity of hippo-Yes-associated protein (Hippo-YAP). Ligustrazine blocks the Notch pathway to improve the morphology and abnormality of chondrocytes. Oleanolic acid reduces the destruction and degeneration of cartilage matrix via the estrogen signaling pathway. The above summary aims to provide references for future clinical and experimental research on KOA.

ABSTRACT

Total knee arthroplasty, as a common treatment option for advanced knee osteoarthritis, can alleviate the clinical symptoms of patients. Deep vein thrombosis of the lower extremity is the most common complication of total knee arthroplasty. Previous studies have shown that the occurrence of deep vein thrombosis after total knee arthroplasty is mostly related to the overexpression of inflammatory factors in vivo. Nuclear transcription factor-κB, Toll-like receptor 4, phosphatidylinositol 3-kinase/protein kinase B, tumor necrosis factor, and nuclear transcription factor E2-related factor 2 are typical signaling pathways related to inflammation. Regulating the expression of the signaling pathways can intervene the formation of inflammatory factors. Inhibiting the formation of inflammatory factors can help suppress the activation of platelets, thereby blocking thrombosis. According to previous research, Chinese medicine monomers, Chinese medicine extract, and compound Chinese medicine prescriptions all directly or indirectly inhibit the expression of inflammatory factors by regulating the above signaling pathways, thereby suppressing the occurrence of deep vein thrombosis after total knee arthroplasty. Therefore, Chinese medicine can reduce postoperative complications and promote postoperative recovery of patients at low cost with small side effects. This article summarizes the research on Chinese medicine intervention on deep vein thrombosis-related signaling pathways after total knee arthroplasty, which is expected to lay a basis for the in-depth study and clinical application of Chinese medicine in deep vein thrombosis.
