Effect of Dioscorea villosa extract and the phytoestrogen diosgenin on ovariectomized mice with zymosan-induced arthritis

Abstract Humans are exposed to natural compounds such as phytoestrogens primarily through diet and supplements. These compounds promote health by alleviating the symptoms and illnesses associated with menopause and arthritis. Diosgenin (DSG) occurs naturally in plants such as Dioscorea villosa (DV) and binds to estrogen receptors, so it may have similar effects to this hormone, including against arthritis. Thus, we investigated the effect of chronic treatment with dry extract of DV and its phytoestrogen DSG on ovariectomized mice with arthritis. We found that dry extract of Dioscorea villosa (DV) contains the phytoestrogen diosgenin (DSG) in its composition. Furthermore, arthritic mice treated with DV and DSG showed reduced neutrophil accumulation in the articular cartilage. Also, the dry extract of DV administered orally (v.o) did not alter the leukocyte count in the joints or promote changes in the reproductive tract. However, DSG altered these parameters, with possible beneficial effects by reducing symptoms related to reproductive aging. Thus, oral treatment with dry extract of DV and subcutaneous (s.c) treatment with DSG showed promise by acting against inflammation caused by arthritis and reducing symptoms in the reproductive tract due to menopause.

Effects of low-level laser therapy on acupuncture points on knee pain and function in knee osteoarthritis

SUMMARY OBJECTIVE: Knee osteoarthritis is a common and disabling disease. We aimed to examine the effect of low-level laser therapy in addition to routine physical therapy modalities (transcutaneous electrical stimulation, superficial heating modality of infrared, ultrasound, and exercise) on the functional status and pain in knee osteoarthritis. METHODS: Patients with knee osteoarthritis (n=71) who underwent physical therapy (transcutaneous electrical stimulation, infrared, ultrasound, exercise therapy, and low-level laser therapy) were retrospectively screened. Patients who received low-level laser therapy on acupuncture points, transcutaneous electrical stimulation, infrared, ultrasound, and exercise were included in the low-level laser therapy (+) (n=35), and patients who received only transcutaneous electrical stimulation, ultrasound, infrared, and exercise were included in the low-level laser therapy (-) group (n=36). The Visual Analog Scale for activity pain, Lysholm Knee Scoring Scale, and walking and stair climbing tests were used before and after treatment obtained from patient files. RESULTS: The post-treatment Visual Analog Scale activity score and walking and stair climbing test results were statistically significantly lower in the low-level laser therapy (+) group than in the low-level laser therapy (-) group. There was no significant difference in post-treatment Lysholm Knee Scoring Scale scores between the two groups. In both groups, the Visual Analog Scale activity, Lysholm Knee Scoring Scale, and walking and stair climbing test scores statistically significantly decreased after treatment. CONCLUSION: Knee osteoarthritis increases with aging and creates significant functional limitations. low-level laser therapy with routine physiotherapy contributed to the improvement in the pain and functional status of the patients with knee osteoarthritis. Low-level laser therapy can be recommended in osteoarthritis treatment guidelines with the support of further studies, which is an easy-to-apply, effective, and reliable method.

Bone protective effect of sinomenine against monosodium iodoacetate induced knee and hip injury in rat model: an inflammatory pathway

Purpose: Osteoarthritis (OA) is a degenerative joint disease which is categorized via destruction of joint cartilage and it also affects the various joints, especially knees and hips. Sinomenine active phytoconstituents isolated from the stem of Sinomenium acutum and already proof anti-inflammatory effect against the arthritis model of rodent. In this experimental protocol, we scrutinized the anti-osteoarthritis effect of sinomenine against monosodium iodoacetate (MIA) induced OA in rats. Methods: MIA (3 mg/50 µL) was used for inducing the OA in the rats, and rats received the oral administration of sinomenine (2.5, 5 and 7.5 mg/kg body weight) up to the end of the experimental study (four weeks). The body and organs weight were estimated. Aggrecan, C-terminal cross-linked telopeptide of type II collagen (CTX-II), glycosaminoglycans (GCGs), monocyte chemoattractant protein-1 (MCP-1), Interferon gamma (IFN-γ), antioxidant, inflammatory cytokines, inflammatory mediators and matrix metalloproteinases (MMP) were analyzed. Results: Sinomenine significantly (P < 0.001) boosted the body weight and reduced the heart weight, but the weight of spleen and kidney remain unchanged. Sinomenine significantly (P < 0.001) reduced the level of nitric oxide, MCP-1 and improved the level of aggrecan, IFN-γ and GCGs. Sinomenine remarkably upregulated the level of glutathione, superoxide dismutase and suppressed the level of malonaldehyde. It effectually modulated the level of inflammatory cytokines and inflammatory mediators and significantly (P < 0.001) reduced the level of MMPs, like MMP-1, 2, 3, 9 and 13. Conclusions: Sinomenine is a beneficial active agent for the treatment of OA disease.

Clinical and functional evaluation of wrists and hands of spinal cord injured patients / Avaliação clínica e funcional de mãos e punhos de pacientes lesados medulares

ABSTRACT Introduction: The inability of the spinal cord to propagate sensory and motor stimuli as a result of the disruption of the nerve tracts is called spinal cord injury. Objective: This study analyzes clinically and radiologically the hands and wrists of spinal cord injured patients, evaluating their motor and sensitive functionality, in order to determine if these patients are more likely to develop degenerative alterations. Methods: 14 patients (8 paraplegics and 6 tetraplegics) were evaluated, undergoing anamnesis and clinical examination - a scale of muscular strength (MRC - Medical Research Council) and the amplitude measurement of the movement with a manual goniometer (ROM), were used for objective evaluation - and x-ray exams. The results were compared with pre-existing data from other studies. Results: When asked, only one of the 14 observed patients complained about constant wrist pain, described as level 3 (weak to moderate), based on the visual analog scale (VAS). The motor evaluation, MRC and ROM divided the group of patients into two subgroups: paraplegic and tetraplegic patients. The x-ray analysis showed, based on Kellgren and Lawrence classification, that all exam images fit grades 1 or 2 of osteoarthritis and osteoarthrosis. Conclusion: In conclusion, spinal cord injured patients showed none or minimal clinical and radiological signs of osteoarthritis on hands or wrists. Overall, the hands and wrists of spinal cord-injured patients behave similarly to noninjured patients. Level of Evidence III; Retrospective Comparative Study.

RESUMO Introdução: A incapacidade da medula espinhal de propagar estímulos sensoriais e motores como resultado do rompimento das vias nervosas é chamada de lesão da medula espinhal. Objetivo: Este estudo analisa clínica e radiograficamente mão e punhos de pacientes lesados medulares, avaliando função motora e sensitiva, a fim de determinar se estes pacientes estariam mais propensos a alterações degenerativas. Métodos: 14 pacientes (8 paraplégicos e 6 tetraplégicos) foram avaliados, passando por anamnese e exame clínico - sendo escala de força muscular (MRC - Medical Research Council) e a medição da amplitude de movimento com um goniômetro manual (ROM) foram utilizados para análise objetiva - e radiografias. Os dados obtidos foram comparados com literatura preexistente. Resultados: Quando questionados, apenas um dos 14 pacientes observados referiu dor crônica nos punhos, descrita como nível 3 (fraca a moderada), baseada na escala visual analógica. A avaliação motora, MRC e ROM dividiram os pacientes em 2 subgrupos: pacientes paraplégicos e tetraplégicos. A análise radiográfica mostrou, baseada na classificação de Kellgren e Lawrence, que todas as imagens se encaixam nos graus 1 ou 2 de osteoartrite e osteoartrose. Conclusão: Conclui-se, então, que pacientes lesados medulares apresentam nenhuma ou mínimas alterações clínicas e radiológicas para osteoartrite ou osteoartrose de punhos ou mãos. Ou seja, no geral, mãos e punhos de pacientes lesados medulares comportam-se como os pacientes sem lesão medular. Nível de Evidência III; Estudo Retrospectivo Comparativo.

Role of Interleukin-17 family cytokines in disease severity of patients with knee osteoarthritis

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.

Genetic polymorphism of WNT9A is functionally associated with thumb osteoarthritis in the Chinese population

Abstract Background In a recent genome-wide association study, novel genetic variations of WNT9A were reported to be involved in the etiopathogenesis of thumb osteoarthritis (TOA) in Caucasians. Our purposes were to replicate the association of WNT9A with the development of TOA in the Chinese population and to further unveil the functional role of the risk variants. Methods SNP rs11588850 of WNT9A were genotyped in 953 TOA patients and 1124 healthy controls. The differences of genotype and allele distributions between the patients and healthy controls were evaluated using the Chi-square test. Luciferase Reporter Assay was performed to investigate the influence of variant on the gene expression. Results There was significantly lower frequency of genotype AA in TOA patients than in the controls 74.9% vs. 81.9%, p < 0.001). The frequency of allele A was remarkably lower in the patients than in the controls (86.3% vs. 90.5%, p < 0.001), with an odds ratio of 0.66 (95% CI = 0.54-0.80). Luciferase Reporter Assay showed that the construct containing mutant allele G of rs11588850 displayed 29.1% higher enhancer activity than the wild allele A construct (p < 0.05). Conclusions Allele G of rs11588850 was associated with the increased risk of TOA possibly via up-regulation of WNT9A expression. Further functional analysis into the regulatory role of rs11588850 in WNT9A expression can shed new light on the genetic architecture of TOA. Key Points Genetic variants of WNT9A were associated with the incidence and severity of TOA. Allele G of rs11588850 was associated with an increased transcriptional activity of WNT9A promoter. Allele G of rs11588850 may add to the risk of TOA possibly via up-regulation of WNT9A expression. Further functional analysis into the regulatory role of rs11588850 in WNT9A expression can shed new light on the genetic architecture of TOA.

Traditional Chinese Medicine Regulates Autophagy to Prevent and Treat Osteoarthritis： A Review / 中国实验方剂学杂志

Osteoarthritis （OA） is a common chronic， highly prevalent， painful， and disabling degenerative joint disease. It has imposed a heavy burden on social healthcare and patients' psychology and economy due to its clinical symptoms such as impaired joint mobility and severe joint pain and the immature therapies. Studies have shown that OA is closely associated with articular cartilage dysfunction， synthesis and degradation disorders of chondrocyte extracellular matrix （ECM）， and joint inflammation. Moderate autophagy can restore the function of damaged chondrocytes， regulate chondrocyte apoptosis， and promote the synthesis and metabolism of ECM to alleviate the inflammation of joints and delay the onset and progression of OA. According to the clinical symptoms， OA can be classified into the category of impediment in traditional Chinese medicine. With the theories of holistic conception， treatment based on syndrome differentiation， and individualised diagnosis and treatment， traditional Chinese medicine has demonstrated definite effects in the treatment of OA in thousands of years of practice. Moreover， traditional Chinese medicine causes mild adverse reactions， and the patients have high tolerance and acceptance. This paper briefly explains the roles of autophagy and the related regulatory proteins， such as Unc-51-like autophagy-activated kinase 1 （ULK1）， Beclin-1， and microtubule-associated protein light chain 3 （LC3）， and details the latest research achievements in the prevention and control of OA by traditional Chinese medicines and its related markers via the regulation of autophagy， so as to provide a idea for the in-depth research in this field and the clinical application of traditional Chinese medicine in preventing and treating OA.

Does total knee arthroplasty affect pelvic movements? A prospective comparative study

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 Objective: To develop a convolutional neural network (CNN) model, trained with the Brazilian "Estudo Longitudinal de Saúde do Adulto Musculoesquelético" (ELSA-Brasil MSK, Longitudinal Study of Adult Health, Musculoskeletal) baseline radiographic examinations, for the automated classification of knee osteoarthritis. Materials and Methods: This was a cross-sectional study carried out with 5,660 baseline posteroanterior knee radiographs from the ELSA-Brasil MSK database (5,660 baseline posteroanterior knee radiographs). The examinations were interpreted by a radiologist with specific training, and the calibration was as established previously. Results: The CNN presented an area under the receiver operating characteristic curve of 0.866 (95% CI: 0.842-0.882). The model can be optimized to achieve, not simultaneously, maximum values of 0.907 for accuracy, 0.938 for sensitivity, and 0.994 for specificity. Conclusion: The proposed CNN can be used as a screening tool, reducing the total number of examinations evaluated by the radiologists of the study, and as a double-reading tool, contributing to the reduction of possible interpretation errors.

Resultados: A RNC desenvolvida apresentou área sob a curva característica de operação do receptor de 0,866 (IC 95%: 0,842-0,882). O modelo pode ser calibrado para alcançar, não simultaneamente, valores máximos de 0,907 para acurácia, 0,938 para sensibilidade e 0,994 para especificidade. Conclusão: A RNC desenvolvida pode ser utilizada como ferramenta de triagem, reduzindo o número total de exames avaliados pelos radiologistas do estudo, e/ou como ferramenta de segunda leitura, contribuindo com a redução de possíveis erros de interpretação.

Acupuncture in the Treatment of a Series of Patients with Chronic Pain Associated with Hip Osteoarthritis / Acupuntura no tratamento de uma série de pacientes com dor crônica associado à osteoartrite de quadril

Abstract Objective Hip osteoarthritis (HO) causes pain and deranges functioning. Surgical treatment is the preferred approach in severe cases, but clinical comorbidities, age and the long waiting list may compromise quality of life. This study aimed to describe the results of acupuncture for the control pain and improvement of functioning in subjects with HO. Method Twelve severe HO patients were treated with ten weekly sessions of a standardized acupuncture point protocol. Pain intensity was assessed with the Visual Analog Pain Scale (VAS) and quality of life with WOMAC Index. Results Pain intensity (VAS) reduced from 75.8 ± 18.8 mm to 20.0 ± 22.6 mm after 10 acupuncture sessions and 48.3 ± 26.6mm in the follow-up (ANOVA F = 7.99; p < 0.001). WOMAC Index values reduced from 74.7 ± 12.7 to 45.7 ± 22.1 and 54.6 ± 22.9 at the same timepoints. Conclusion Acupuncture is an effective conservative rehabilitation strategy to reduce pain and improve quality of life in subjects with severe HO.

Resumo Objetivo A osteoartrite (OA) de quadril causa dor e perda da funcionalidade. O tratamento cirúrgico é a procedimento de escolha nos casos graves, mas as comorbidades clínicas, a idade e a longa lista de espera podem comprometer a qualidade de vida.

Tapentadol extended-release as a therapeutic strategy for pain control in cases of osteoarthritis. Case reports / Tapentadol de liberação prolongada como estratégia terapêutica para o controle da dor em casos de osteoartrite. Relato de casos

ABSTRACT BACKGROUND AND OBJECTIVES: Osteoarthritis affects many individuals worldwide and is caused by multiple factors that lead to joint wear and tear, inflammation and, consequently, chronic pain that is difficult to treat. It is predominant in seniors, but not restricted to older age groups. Pain reduction is prioritized when facing crises, so that rehabilitation work and postural corrections can be applied later. The present study aimed to evaluate the analgesic potential of tapentadol extended-release (ER) in three patients with osteoarthritis who had undergone numerous previous treatments and had a history of moderate to severe chronic pain. CASE REPORTS: Three women, aged 49, 75 and 86 years old, diagnosed with osteoarthritis, with complaints of severe pain and who had undergone numerous therapies including drug use, without significant pain control were included in the study. The use of tapentadol ER was recommended and adjusted to each patient according to the intensity of pain. All of them responded satisfactorily and returned to their daily activities. One of them presented nausea after two days of tapentadol use, which was controlled with an antiemetic drug only during the two days of nausea CONCLUSION: Tapentadol ER was effective in controlling pain from osteoarthritis in the three cases evaluated, without serious adverse effects. The period and dosage of tapentadol ER must be in accordance with the clinical evolution of each patient.

RESUMO JUSTIFICATIVA E OBJETIVOS: A osteoartrite afeta muitos indivíduos em todo o mundo, é causada por múltiplos fatores que conduzem ao desgaste articular, a inflamações e, consequentemente, a dores crônicas de difícil tratamento. É predominante em idosos, mas não restrita às faixas etárias mais elevadas. A diminuição da dor é priorizada diante das crises, para que trabalhos de reabilitação e correções posturais possam ser aplicados posteriormente. O presente estudo teve por objetivo avaliar o potencial analgésico do tapentadol de liberação prolongada (LP) em três pacientes com osteoartrite que já haviam passado por inúmeros tratamentos prévios, com histórico de dor crônica de moderada a intensa. RELATO DOS CASOS: Três pacientes do sexo feminino, com idades de 49, 75 e 86 anos, diagnosticadas com osteoartrite, com queixas de dor intensa e que haviam passado por inúmeras terapias e uso de fármacos, sem controle significativo da dor. O uso do tapentadol LP foi recomendado e ajustado a cada paciente conforme a intensidade da dor e todas elas apresentaram resposta satisfatória e retomaram suas atividades diárias. Uma delas apresentou náusea após dois dias de uso do fármaco, que foi controlada com um fármaco antiemético somente durante dois dias de enjoo. CONCLUSÃO: O tapentadol LP foi efetivo para controlar as dores decorrentes da osteoartrite nos três casos avaliados, sem efeitos adversos graves. O período e a dose do tapentadol LP deve considerar a evolução clínica de cada paciente.

Correlation between body mass index and joint pain intensity with gait performance in individuals with osteoarthritis / Correlação entre o índice de massa corporal e intensidade da dor articular com o desempenho da marcha em indivíduos com osteoartrite

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.

Differences According to the Type of Exogenous Hyaluronic Acid and its Frequency of Infiltration in the Treatment of Temporomandibular Osteoarthritis / Diferencias Según el Tipo de Ácido Hiaurónico Exógeno y su Frecuencia de Infiltración en el Tratamiento de la Osteoartritis Temporomandibular

SUMMARY: One of the most important minimally invasive treatments today in temporomandibular joint osteoarthritis (TMJ- OA) is the intra-articular exogenous hyaluronic acid (HA) injection, which has yielded good results in pain relief and improves mandibular function with few side effects. However, the effectiveness of HA continues to be controversial, partly due to the heterogeneity in the injection protocols in their molecular weight, viscosity and frequency of infiltration, among other properties. The aim of this review is to identify the differences in the histological and clinical effects of the different types of HA and the frequency of infiltration on TMJ-OA treatment. Materials and methods: A bibliographic search was performed in the PubMed, Web of Science and Scopus databases. The search was limited up to September 2022. Search terms included "osteoarthritis", "hyaluronic acid, "molecular weight", "concentration", "viscosity", "dose" and "temporomandibular", using AND/OR as Boolean terms. Results: Exogenous HA in its different molecular weights offers an improvement in histological and clinical characteristics. Apparently, low and medium molecular weight HA presents better results. No clinical studies related to the degree of HA viscosity were found. Respect to the frequency of infiltration, single injection, weekly injections for 3 weeks, weekly injections for 5 weeks and other protocols are used. However, their comparison is complex. There seems to be differences in the effects of the different HA preparations for the treatment of TMJ-OA, mainly in their molecular weight. However, the evidence remains scant.

Uno de los tratamientos mínimamente invasivos más importantes en la actualidad en la artrosis de la articulación temporomandibular (OATM) es la inyección intraarticular de ácido hialurónico (AH) exógeno, que ha dado buenos resultados en el alivio del dolor y mejora la función mandibular con pocos efectos secundarios. Sin embargo, la efectividad del AH continúa siendo controversial, en parte debido a la heterogeneidad en los protocolos de inyección en cuanto a su peso molecular, viscosidad y frecuencia de infiltración, entre otras propiedades. El objetivo de esta revisión fue identificar las diferencias en los efectos histológicos y clínicos de los diferentes tipos de HA y la frecuencia de infiltración en el tratamiento de TMJ-OA. Se realizó una búsqueda bibliográfica en las bases de datos PubMed, Web of Science y Scopus. La búsqueda se limitó hasta septiembre de 2022. Los términos de búsqueda incluyeron "osteoartritis", "ácido hialurónico", "peso molecular", "concentración", "viscosidad", "dosis" y "temporomandibular", utilizando AND/OR como términos booleanos. El HA exógeno en sus diferentes pesos moleculares ofrece una mejora en las características histológicas y clínicas. Aparentemente, el AH de bajo y medio peso molecular presenta mejores resultados. No se encontraron estudios clínicos relacionados con el grado de viscosidad del HA. Respecto a la frecuencia de infiltración, se utilizan inyecciones únicas, inyecciones semanales durante 3 semanas, inyecciones semanales durante 5 semanas y otros protocolos. Sin embargo, su comparación es compleja. Parece haber diferencias en los efectos de las diferentes preparaciones de HA para el tratamiento de la OA-TMJ, principalmente en su peso molecular. Sin embargo, la evidencia sigue siendo escasa.

Histological effect of platelet-rich plasma on temporomandibular joint osteoarthritis: systematic review in animal models

SUMMARY: The aim of this systematic review was to assess the histological effects of platelet-rich plasma (PRP) on temporomandibular joint osteoarthritis (TMJ-OA) in animal models. A systematic search was performed using PubMed, WoS, EMBASE, Science Direct and SCOPUS databases. The inclusion criteria were experimental studies in animal models that evaluated the use of PRP as a treatment for TMJ-OA with or without arthrocentesis/arthroscopy. Comparison was made to a healthy control group or to other treatment. The variables evaluated were the histological effects of the treatments, characteristics of the primary articles, characteristics of the sample studied and the risk of bias. The systematic search identified 120 studies. Eventually 5 studies were included in the analysis. Four of the studies showed a statistically significant repair in joint tissues and improvement of cartilage thickness in animals treated with PRP. The global risk of bias was unclear. The results of this systematic review suggest that PRP treatment in TMJ-OA has benefits at the histological level in cartilage, articular disc and articular bone tissue in animal models. However, due to the low number of studies and the risk of bias, further research is needed to recommend its use.

El objetivo de esta revisión sistemática fue evaluar los efectos histológicos del plasma rico en plaquetas (PRP) en la osteoartritis de la articulación temporomandibular (ATM-OA) en modelos animales. Se realizó una búsqueda sistemática en las bases de datos PubMed, WoS, EMBASE, Science Direct y SCOPUS. Los criterios de inclusión fueron estudios experimentales en modelos animales que evaluaran el uso de PRP como tratamiento para la ATM-OA con o sin artrocentesis/ artroscopia. La comparación se realizó con un grupo de control sano o con otro tratamiento. Las variables evaluadas fueron los efectos histológicos de los tratamientos, las características de los artículos primarios, las características de la muestra estudiada y el riesgo de sesgo. La búsqueda sistemática identificó 120 estudios. Finalmente se incluyeron 5 estudios en el análisis. Cuatro de los estudios mostraron una reparación estadísticamente significativa en los tejidos articulares y una mejora del grosor del cartílago en los animales tratados con PRP. El riesgo global de sesgo fue incierto. Los resultados de esta revisión sistemática sugieren que el tratamiento con PRP en la ATM-OA tiene beneficios a nivel histológico en el cartílago, el disco articular y el tejido óseo articular en modelos animales. Sin embargo, debido al escaso número de estudios y al riesgo de sesgo, se necesitan investigaciones adicionales para recomendar su uso.
