RESUMEN
@#Objective To evaluate the influence of routine lateral release to the clinical outcomes after total knee arthroplasty without patellar resurfacing.Methods The study involved all patients divided into two groups using a randomised group method.During total knee arthroplasty(TKA),forty-three patients were treated with lateral release in the treatment group,while Forty-two patients in the control group were not treated with lateral release.Both groups were assessed for anterior knee pain,patient satisfaction,Knee Surgery Society(KSS)score,KSS function score,patella score,and incidence of postoperative complications.Results After 24 months of follow-up,the treatment group was found to have a lower incidence of anterior knee pain compared to the control group(P<0.05),and there were no statistically significant differences in postoperative satisfaction,complication rate,KSS knee score,KSS function score,and patella score between the two groups(P>0.05).Conclusion The study suggests that routine lateral release can reduce anterior knee pain and does not increase the risk of postoperative complications after total knee arthroplasty without patellar resurfacing.
RESUMEN
BACKGROUND:Lower limb peri-knee muscle strength training and neuromuscular electrical stimulation are generally safe and effective rehabilitation methods for patellofemoral joint pain,but the mechanism of their intervention is still unclear. OBJECTIVE:To determine the effect of muscle strength training combined with neuromuscular electrical stimulation on pain,lower extremity function and biomechanical characteristics in patients with patellofemoral pain. METHODS:Thirty-seven patients with patellofemoral pain were randomly divided into muscle strength training combined with electrical stimulation group(trial group,n=19)and muscle strength training group(control group,n=18).Both groups underwent intervention training for 6 weeks,three times a week.The visual analog scale and anterior knee pain scale were used to evaluate the pain level and functional level of the knee.Kinematic and kinetics data during running were collected by using an infrared motion capture system and a three-dimensional force platform simultaneously.A two-way analysis of variance with repeated measures(group*time)was applied to analyze the data. RESULTS AND CONCLUSION:(1)After the intervention,the visual analog scale scores of the trial group and the control group were significantly decreased(P<0.001),and the anterior knee pain scale scores were significantly increased(Ptrial group<0.001,Pcontrol group=0.001)in the trial group and control group.The anterior knee pain scale scores of the trial group were significantly higher compared to the control group after the intervention(P=0.001).(2)The peak knee flexion angle(P=0.011),peak knee extension moment(P<0.001),the peak knee internal rotation moment(P=0.008),the peak patellofemoral stress(P<0.001)and the peak patellofemoral contact force(P<0.001)were significantly decreased in the trial and control groups during running after the intervention compared with those before the intervention.(3)In conclusion,both muscle strength training and muscle strength training combined with electrical stimulation training are helpful to improve the subjective pain and lower limb function of patellofemoral pain patients,enhance the movement pattern during running and reduce the stress of the patellofemoral joint.Compared with muscle strength training alone,muscle strength training combined with electrical stimulation can improve lower limb function more significantly.
RESUMEN
Resumen: El dolor anterior de rodilla es una condición que afecta a pacientes adolescentes y adultos jóvenes, siendo una de las consultas más comunes y desafiantes para el cirujano de rodilla. La gran cantidad de diagnósticos diferenciales, lo convierten en un síndrome particular, que solo presentan en común la presencia de dolor retro o peripatelar agravado por al menos una actividad que cargue la articulación en flexión. Desde un punto de vista fisiopatológico, debe considerarse una lesión por sobrecarga, donde la unidad estructural del tejido se encuentra dañada o excedida su capacidad de respuesta reparadora. El diagnóstico es clínico. Las imágenes debiesen reservarse para un grupo particular de pacientes. La intervención precoz es fundamental para lograr resultados favorables. El tratamiento conservador es el estándar de oro y se basa en un manejo multimodal validado por consensos internacionales. Basados en una categorización por clínica e imágenes, podemos tener una guía de aquellos cuadros que son susceptibles de manejo quirúrgico. El objetivo de la intervención es reducir el estrés articular. La presente revisión define un algoritmo simplificado de estudio y manejo en dolor anterior de rodilla.
Abstract: Anterior knee pain is a common condition that affects adolescent and young adult patients, being one of the most challenging consultations for a knee surgeon. The large number of distinct diagnoses makes it a peculiar syndrome, the only similarities being the presence of retro or peripatellar pain aggravated by at least one activity that loads the joint in flexion. From a pathophysiological perspective, an overuse injury should be considered, where the structural unit of the tissue is damaged or its capacity for reparative response is exceeded. The diagnosis is clinical. Images should be reserved for a particular group of patients. Early intervention is essential to achieve favorable results. Conservative treatment is the gold standard and it is based on multimodal management validated by international consensus. Based on a categorization by clinic and images, we can have a guide to those etiologies that are susceptible to surgical management. The goal of the intervention is to reduce joint stress. The present review defines a simplified algorithm for the study and management of anterior knee pain.
RESUMEN
Objective:To investigate the effects of patelloplasty combined with cartilage surface resection on early function and anterior knee pain during total knee arthroplasty(TKA).Methods:This is a prospective controlled study, 100 patients with knee osteoarthritis(KOA) who received TKA treatment in Zoucheng People′s Hospital of Shandong Province from February 2021 to April 2022 were selected and divided into the combined group and the control group using the random number table method, 50 cases in each group. The combined group received patelloplasty combined with cartilage surface resection during TKA, while the control group only received patelloplasty. Preoperative osteoarthritis Kellgren-Lawrance (K-L) grade, joint motion (ROM), the operation time and the decrease of hemoglobin in two groups were recorded.Knee function was evaluated by Hospital for Special Surgery(HSS) knee score at 1, 3, 6, and 12 months after surgery. Anterior knee pain during stair climbing was evaluated by visual analogue scale(VAS), and recovery of patellofemoral joint was evaluated by Feller score system. The measurement data were represented as mean±standard deviation( ± s), and the comparison between groups was conducted using the t-test; the comparison of count data between groups was conducted by Chi-square test. Results:There was no significant difference in preoperative K-L grading and ROM between the two groups ( P> 0.05). The operation time of the combined group was longer than that of the control group[(71.49±9.34) min vs (66.27±8.22) min], the difference was statistically significant ( P <0.05), and there was no statistical significance in the decrease of hemoglobin between the two groups ( P>0.05). At 3, 6 and 12 months after treatment, the HSS scores of the combined group were higher than those of the control group [3 months: (76.93±8.26) vs (71.74±7.84), 6 months: (85.72±6.27) vs (81.47±6.19), 12 months: (88.64±5.27) vs (85.72±4.85)], the difference were statistically significant ( P <0.05). At 1, 3, 6 and 12 months after treatment, the VAS scores of anterior knee pain in combined group were lower than those in control group [1 months: (2.54±0.48) vs (2.77±0.63), 3 months: (2.02±0.53) vs (2.58±0.45), 6 months: (1.32±0.35) vs (1.97±0.38), 12 months: (1.14±0.33) vs (1.75±0.35)], the difference were statistically significant ( P <0.05). The incidence of anterior knee pain at 3, 6 and 12 months after operation in combined group was lower than that in control group [3 months: 20.0% vs 38.0%, 6 months: 14.0% vs 32.0%, 12 months: 10.0% vs 28.0%], the difference were statistically significant ( P <0.05). At 3, 6 and 12 months after treatment, the patellar Feller score in the combined group was higher than that in the control group[3 months: (18.63±3.52) vs (15.36±3.28), 6 months: (22.27±3.18) vs (19.63±3.48), 12 months: (25.82±3.27) vs (22.47±3.47)], the difference were statistically significant ( P <0.05). Conclusion:Patelloplasty combined with cartilage surface resection during TKA can effectively prevent the occurrence of postoperative anterior knee pain and improve the therapeutic effect.
RESUMEN
Abstract BACKGROUND: The relationships between the morphometric structure of the patellofemoral joint, patella type and chondromalacia patella are still a matter of debate. OBJECTIVE: To identify the prevalence of chondromalacia patella by determining the patella type and making patellofemoral morphometric measurements. DESIGN AND SETTING: Retrospective cohort study in an orthopedics and traumatology clinic in Turkey, conducted between June 2017 and November 2019. METHODS: This study involved 562 knees of 522 patients with anterior knee pain (246 males and 316 females; mean age 46.59 years). The patients were grouped according to presence of chondromalacia patella (group I) or absence of chondromalacia patella (group II). The patella type, lateral trochlear inclination, medial trochlear inclination, trochlear angle, sulcus angle, patellar tilt and Insall-Salvati index were assessed. Group comparisons were made using chi-square tests or Student t tests. The r value was used to determine the magnitude of relationships between pairs of variables. RESULTS: Among the 562 knees evaluated, 265 (50.71%) presented type I patella, 195 (36.7%) type II, 100 (12.3%) type III and 2 (0.3%) type IV. Group I consisted of 448 knees and group II consisted of 114 knees. Significant differences were found between the groups in terms of age, gender, patella type and lateral inclination angles (P < 0.05). CONCLUSION: Detecting the patella type and making lateral inclination measurements in patients with anterior knee pain are of great importance for diagnosing suspected chondromalacia patella, particularly in the early degenerative period.
RESUMEN
A avaliação fisioterapêutica é fundamental para o diagnóstico cinético funcional da Dor Femoropatelar (DFP), bem como para mensuração da dor, limitações funcionais e déficits musculoesqueléticos destes pacientes. A avaliação também permite avaliar prognóstico, assim como evolução do tratamento fisioterapêutico conservador. Entretanto, devido à falta de padronização e validação dos instrumentos de medida, torna-se dificultosa a escolha da ferramenta mais apropriada para avaliar o processo de reabilitação dos pacientes com DFP. O objetivo deste estudo foi identificar os instrumentos mais adequados para a avaliação da dor, função e cinemática do tronco e membro inferior em pacientes com DFP. Para tal, foi realizado uma consulta à base de dados PubMed, utilizando as palavras-chave: "patellofemoral pain syndrome", "physical therapy" "physiotherapy", "evaluation", "measurement", "kinematics", "functional test", "functional activity". Sendo considerado, artigos em idioma inglês publicados entre 2000 a 2019. Os critérios de inclusão foram: 1) estudos que abordassem instrumentos de avaliação, sendo eles, escalas de dor, questionários que mensuram limitação funcional, e testes funcionais usados para analisar a cinemática do tronco e membro inferior; 2) estudos que analisassem as propriedades clinimétricas destes instrumentos; 3) população com DFP. Foram encontrados 1.399 artigos, sendo que após a retiradas de duplicatas, leitura de títulos e resumos, foram incluídos 13 estudos nesta revisão. Tais estudos foram classificados de acordo com Oxford Centre for Evidence-Based Medicine. De acordo com a análise crítica dos artigos, pode-se afirmar que a Escala Visual Analógica e a Escala Numérica são ferramentas adequadas para mensurar a intensidade da dor nestes pacientes. O Anterior Knee Pain Scale, Activities of Daily Living Scale, Pain Severity Scale e Osteoarthritis Outcome Score Patellofemoral Subscale são eficazes para avaliar dor e função em pacientes com DFP, sendo os dois primeiros, os mais indicados. A escolha dos testes funcionais deverá ser realizada de acordo com o nível de capacidade física do paciente, sendo o Step Down Test indicado para a população sedentária, o Single Leg Squat e Single Leg Landing para população ativa, e o Single Leg Triple Hop Test para pacientes atletas.(AU)
: Physical therapy evaluation is fundamental for the functional diagnosis of Patellofemoral Pain (PFP), as well as for measuring pain, functional limitations and musculoskeletal deficits of these patients. The evaluation also allows the evaluation of prognosis, as well as evolution of conservative physiotherapeutic treatment. However, due to the lack of standardization and validation of measurement instruments, it is difficult to choose the most appropriate instrument to evaluate the rehabilitation process of patients with PFP. The aim of this study was to identify the most appropriate instruments for the evaluation of pain, function and kinematics of the trunk and lower limb in patients with PFP. For this purpose, a search was performed to the PubMed database, using the keywords: "patellofemoral pain syndrome", "physical therapy" "physiotherapy", "evaluation", "measurement", "kinematics", "functional test", "functional activity". Being considered, articles in English published between 2000 and 2019. The inclusion criteria were: 1) studies addressing assessment instruments, such as pain scales, questionnaires that measure functional limitation, and functional tests used to analyze the kinematics of the trunk and lower limb; 2) studies analyzing the clinimetric properties of these instruments; 3) population with PFP. A total of 1,399 articles were found, and after the removal of duplicates, reading of titles and abstracts, 13 studies were included in this review. Such studies were classified according to Oxford Centre for Evidence-Based Medicine. According to the critical analysis of the articles, it can be affirmed that the Visual Analog Scale and the Numerical Scale are adequate tools to measure pain intensity in these patients. The Previous Knee Pain Scale, Activities of Daily Living Scale, Pain Severity Scale and Osteoarthritis Outcome Score Patellofemoral Subscale are effective for assessing pain and function in patients with PFP, the first two being the most indicated. The choice of functional tests should be performed according to the level of physical capacity of the patient, being the Step Down Test indicated for the sedentary population, Single Leg Squat and Single Leg Landing to active population, and Single Leg Triple Hop Test to athletes patients.(AU)

Aims: The purpose of our study was to compare the hip and knee muscle activity before and after a hip abduction exercise program in women with patellofemoral pain (PFP). Methods: Eleven women with PFP were included in our pre/post design study. Participants were assessed before and after 12-week hip abduction exercise program. All participants performed 6 stair climbing repetitions, 3 sets of rope jumps over 30 s and 5 sets of 8 squats to standardize the physical activity level before data collection. We recorded the electromyographic activity from gluteus medius, vastus medialis (VM) and vastus lateralis (VL) for double-legged squat with and without isometric hip abduction. Additionally, participants were asked to perform a step-down test to assess objective function (maximum number of repetitions over 30 s) and completed a clinical evaluation. Results: Longer duration of VM (Mean difference [95% CI]) = -0.97 [-1.48; -0.46], ES [effect size] = 0.66) and VL (-0.81 [-1.35; -0.27], ES = 0.54) were found after the hip abduction exercise program only for free squat. The participants also performed higher number of step-down repetitions (-3.54 [-5.84; -1.25], ES = 1.03) after the hip abduction exercise program and showed improvement in pain reports. Conclusion: A 12-week hip abduction exercise program changed the quadriceps muscle activation pattern and improved pain and objective function of women with PFP. The exercises promoted a longer VM and VL activation duration. Additionally, they promoted a clinical improvement in the patients with PFP.(AU)

Introducción: El síndrome de dolor patelofemoral, se define como aquel dolor retro o peripatelar agravado por al menos 1 actividad que cargue la articulación en flexión. Su diagnóstico, se basa en una correcta anamnesis, examen físico y pruebas de evocación de dolor e inestabilidad. El tratamiento puede ser quirúrgico o conservador, este último, tiene como objetivo disminuir el dolor e inflamación. Sin embargo, a pesar de su alta prevalencia, existen escasos protocolos sobre su manejo, por lo que el objetivo de este trabajo es entregar una revisión de la literatura con información reciente, a modo de dar una recomendación actualizada para su tratamiento. Materiales Y Métodos: Se realizó una revisión no sistemática de estudios publicados entre enero del 2005 y agosto del 2020, utilizando los términos MeSH "Anterior knee pain", "Patellofemoral pain syndrome" y "Treatment". Se usaron como motores de búsqueda PubMed, The Cochrane Library y Trip Data base, excluyendo estudios en animales y población pediátrica. Desarrollo: El tratamiento conservador del síndrome de dolor anterior de rodilla, puede dividirse en intervenciones proximales, locales y distales, todas centradas en una correcta pauta de fortalecimientos y estiramientos de los elementos comprometidos. Se recomienda esquemas asociados de fortalecimientos de core, cadera y rodilla, sin embargo, la literatura no es consistente en pautas de tratamiento protocolizados. Conclusión: El tratamiento conservador del síndrome del dolor patelofemoral depende exclusivamente de los resultados de un correcto examen físico y de las pruebas terapéuticas correspondientes.
Introduction: Patellofemoral pain syndrome is defined as that retro or peripatellar pain aggravated by at least one activity that loads the joint in flexion. Its diagnostic is based on the correct anamnesis, physical exam, pain evocation tests and instability. The treatment can be surgical or conservative, and the last one aims to reduce pain and inflammation. However, despite its high prevalence, there are few protocols concerning its handling, so the main objective of this research is to offer a literature review with updated information, in order to give an updated recommendation for its treatment. Materials And Methods: A non-systematic review of studies published between January 2005 and August 2020 were performed, using the MeSH "Anterior knee pain", "Patellofemoral pain syndrome" and "Treatment". PubMed, The Cochrane Library, and Trip Database were used as search engines, excluding studies in animals and the pediatric population. Development: The conservative treatment of anterior knee pain syndrome, can be divided into proximal, local and distal interventions, all of them focused on a correct guide of strengthening and stretching of the elements involved. Associated schemes of core, hip and knee strengthening are recommended, nevertheless, the literature is not consistent in terms of protocolized treatment guidelines. Conclusion: The conservative treatment of patellofemoral pain syndrome depends exclusively on the results of a correct physical examination, and the corresponding therapeutic tests.

Background: Patello-femoral pain syndrome is a very common complaint seen in adolescence and young adults characterized by pain around and behind the patella. There has been prevalence of trigger points in the quadriceps leading to disruption of the VMO/VL firing pattern due to muscle inhibition by pain. Current studies suggest the use of strengthening exercises for hip and knee not focusing on releasing the trigger points. Releasing these trigger points could give additional benefit to the patient and can also be employed along with other conventional therapies. Purpose of the study: To find out which treatment method gives faster results and works directly on the pain and function of the patient. Objectives: To assess the immediate effect of Dry Needling Vs Ultrasound on releasing Trigger points in Quadriceps in patients with Patello-femoral Pain Syndrome on pain and knee/lower extremity function. Study Design: Randomized Control trail Setting: OPD setting. Participants: 70 patients with chronic anterior knee pain, without any ligament, bony or sensory involvement around the knee. Main outcome measures: Numerical Pain rating scale and Pressure Algometer. Results: In the ultrasound group there was a change of 38.60% seen in NRPS post values with a mean difference of 2.21±1.21 and for pressure algometer a change of 36.23% was seen with a mean difference of 3.08±4.40. In the dry needling group there was a change of 64.53% seen in NRPS post values with a mean difference of 3.07±1.48 and for pressure algometer a change of 56.86% was seen with a mean difference of 8.36±6.90. When compared within group dry needling had a better effect than ultrasound on both NRPS and Pressure algomter. Conclusion: The current study indicates that Dry needling is more effective than ultrasound for reducing pain and increasing functional outcome in patients with patellofemoral pain syndrome.
RESUMEN
Background: Knee pain in general and if to be specific is the pain located anteriorly, and it is widespread among teenage, adults, and the old age population. Among the anterior knee pain etiologies, patellofemoral pain is one of the most common causes of knee pain. One of the significant issues with the patellofemoral pain is that most of the time it is misdiagnosed, or it is underrated for patients' problems, which in the long run lead to severe functional limitations and muscular atrophy. Right clinical diagnosis at an early phase in musculoskeletal conditions is vital. Case summary: The patient presented with chief complaints of diffused pain over right leg tracking it over to the lower back. She presented with a painful limping gait. No tenderness was noted over the lower back; the neural tension test was nonsignificant. Patellar compression test, Clark's test, eccentric step was positive. Severe disuse quadriceps muscular atrophy was noted over-involved limb. Tenderness over the retropatellar surface was significant. The patient was managed with cryotherapy at home, therapeutic ultrasound over the tender area along with Kinesio tapping, proprioception exercises, stretching, and strengthening exercises. Outcome measure: Pain, ROM, girth measurement, gait pattern. Significant improvement was noted in pain on NPS, ROM, and gait pattern in two weeks management. Conclusion: The Physiotherapy management in cases of anterior knee pain, specifically patellofemoral pain, mainly consisting of kinesiotaping, therapeutic ultrasound, cryotherapy, therapeutic exercises are very effective provided right clinical diagnosis, is made. The treatment outcome may be more fruitful if the correct clinical diagnosis is made at an early stage.
RESUMEN
Objective To explore the effect of total knee replacement with preservation of the patellar fat pad on shorterm clinical outcomes.Methods Eighty two patients with end-stage osteoarthritis were treated by total knee arthroplasty in the Central Hospital of Zhumadian City from May 2012 to May 2016 were randomly divided into resection group and reservation group,with 41 patients in each group.Patients in the two groups were given total knee replacement after general anesthesia,the patients in the resection group underwent a complete resection of the patellar fat pad during exposure to the field,while the patellar fat pad was retained partly or completely during the operation in the preservation group.Patients in the two groups were followed up for one year.The knee function score,knee mobility and anterior knee pain score before operation and one year after surgery were evaluated.Patellar tendon shortening and incidence of anterior knee pain of patients in the two groups were analyzed at one year after surgery.Results There was no significant difference in the knee score,functional score,anterior knee pain score and knee mobility before operation between the two group (P > 0.05).At one year after operation,the knee score,functional score and knee flexion degree were higher,while the anterior knee pain score and flexion contracture were lower than those before operation in the two groups (P < 0.05).There was no significant difference in the knee score,functional score,knee flexion degree and flexion contracture at one year after operation between the two groups (P > 0.05),but the anterior knee pain score in the preservation group at one year after operation was lower than that in the resection group (P < 0.05).There was no significant difference in the length of patellar tendon at one week after operation between the two groups (P > 0.05).The length of patellar tendon was longer and the length of patellar tendon shortening in the preservation group at one year after operation was lower than that in the resection group(P <0.05).The incidence of anterior knee pain at one year after operation in the resection group and the preservation group was 22.0% (9/41) and 2.4% (1/41),respectively.The incidence of anterior knee pain at one year after operation in the preservation group was lower than that in the resection group (x2 =7.29,P <0.01).Conclusion To remain the patellar fat pad in the total knee replacement can improve the condition of anterior knee pain and decrease the degree of patellar tendon shortening after operation.
RESUMEN
A 20-year-old National Serviceman presented with left knee pain and swelling after training for his physical fitness test. Lateral knee radiography and magnetic resonance (MR) imaging showed patellar tendon-lateral femoral condyle friction syndrome (PT-LFCFS), on a background of patella alta and patellar malalignment. The patient was treated non-operatively with a course of physiotherapy and given advice on rest and activity modification. PT-LFCFS is a less well-recognised but important cause of anterior knee pain and represents an entity in a spectrum of disorders related to patellofemoral instability. We herein discuss the MR imaging findings specific to and associated with this condition, as well as briefly describing treatment options. In addition, we showcase a range of commonly encountered abnormalities that affect the infrapatellar fat pad and briefly discuss their specific MR imaging findings.

BACKGROUND: Street running is extremely popular worldwide. Despite its benefits, there is evidence that stressful physical activity contributes to the development of lesions on the patellofemoral joint, leading, to anterior knee pain. As an attempt to attain pain control and to improve performance, specific footwear is being developed, aiming to suit particular types of foot strike, and therefore to reduce the risk of injury. OBJECTIVE: To evaluate the effectiveness of the use of customized shoes, based on baropodometric test, for the remission of anterior knee pain among amateur street runners. METHODS: This is a cross-sectional study, using questionnaires based on anthropometric and anatomical data of the runner, type of training, individualized footwear based on baropodometric test and diagnosis of anterior knee pain. In total, 40 athletes were studied, which were divided into two groups: Group 1, with 19 athletes who wore specific shoes for their activity, according to the type of foot strike, and, Group 2, with 21 athletes who used neutral shoes, not prescribed by healthcare professionals. All athletes practiced at the same running field. RESULTS: Most of the athletes were female (70%), The pain remission had no overall statistically significant difference between the two groups. However, significant differences were found between groups A and B regarding the time of occurrence and the extent of AKP. CONCLUSION: The data analysis showed that the use of customized running shoes, based exclusively on baropodometric exams, does not reduce anterior knee pain in amateur street runners, which is consistent with current literature. The improvement of pain with customized shoes, when present, appeared to have a short duration of around three month.
FUNDAMENTO: Corrida de rua é extremamente popular em todo o mundo. Apesar dos seus benefícios, há evidências de que o estresse dessa atividade física contribui para o desenvolvimento de lesões da articulação patelofemoral, levando, à dor anterior do joelho. Como uma tentativa de alcançar o controle da dor e para melhorar o desempenho, calçados específicos foram desenvolvidos, visando adequar determinados tipos de impacto do pé, e, por conseguinte, para reduzir o risco de lesões. OBJETIVO: Avaliar a eficácia do uso de sapatos personalizados, com base no teste de baropodometria, para a remissão de dor anterior do joelho entre os corredores de rua amadores. MÉTODOS: Este é um estudo transversal, por meio de questionários com base nos dados antropométricos e anatômicas do corredor, tipo de treinamento, calçado individualizado com base no teste de baropodometria e diagnóstico da dor anterior do joelho. No total, 40 atletas foram estudados, divididos em dois grupos: Grupo 1, com 19 atletas que usavam sapatos específicos para a sua atividade, de acordo com o tipo de ataque de movimento do pé, e, Grupo 2, com 21 atletas que usaram sapatos neutros, não prescritos por profissionais de saúde. Todos os atletas treinaram em um mesmo campo. RESULTADOS: A maioria dos atletas eram do sexo feminino (70%); não houve diferença estatisticamente significativa entre os dois grupos em termos de remissão da dor. CONCLUSÃO: A análise dos dados mostrou que o uso de tênis personalizados, com base exclusivamente em exames baropodométricos, dor anterior do joelho não reduz a dor os corredores de rua amadores, o que é consistente com a literatura atual. A melhora da dor com sapatos personalizados parece ter uma curta duração de cerca de três meses.

Objective To explore clinical effect of arthroscopic circumpatellar denervation in anterior knee pain of patellofemoral osteoarthritis and its correlation with cartilage degeneration.Methods Totally 104 patients with anterior knee pain of patellofemoral osteoarthritis were randomly divided into two groups.Patients in control group(n =52) were treated with arthroscopic debridement,and those in combined group(n =52) were treated with arthroscopic debridement plus circumpatellar denervation.All the patients were followed-up for 6 months.The WOMAC scores,knee function recovery were compared between two groups,and the changes of WOMAC score among different degrees of cartilage degeneration were analyzed.Results The WOMAC score of pain,morning stiffness and joint function were significantly improved in combined group than those in control group at 6 months after surgery(P < 0.05).At 6 months after surgery,the score of range of activity and walking distance in both groups were all increased,and combined group had more remarkable increase than that of control group(P < 0.05).Compared with before surgery,the total WOMAC score in patients with grade Ⅰ-m at 6 months after surgery significantly decreased (P < 0.05),while there was no significant difference in patients with grade Ⅳ level between before surgery and 6 months after surgery (P > 0.05).Conclusion Arthroscopic debridement plus circumpatellar denervation for anterior knee pain of patellofemoral osteoarthritis can effectively relieve pain symptom,promote the recovery of knee joint function,especially suitable for patients with cartilage degeneration of Ⅰ ~ Ⅲ.
RESUMEN
Objective To investigate the clinical values of sodium hyaluronate combined arthroscopic joint clean-up surgery for the patellofemoral arthritis knee pain patients.Methods From June 2012 to September 2015 in Taihe Hospital Affiliated to Hubei Medical College,136 patellofemoral arthritis knee pain patients were selected and randomly divided into treatment group (68 cases) and control group (68 cases).All patients were given arthroscopic joint clean-up surgery,the control group were given the postoperative glucosamine sulfate capsules treatment,and the treatment group were given the postoperative intra-articular injection of sodium hyaluronate choose treatment,the treatment period was 5 weeks.Results Five weeks after treatment,the response rates in the treatment group and control group were 98.5% (67/68) and 89.7% (61/68),and the effect of the treatment group was better(x2 =4.202,P<0.05).The pain scores in the treatment and control group were (1.34±0.45) points and (2.89±0.62) points,significandy lower than that of before operation ((7.30 ± 0.76) points and (7.31 ± 0.56) points;t =34.855,25.142;P < 0.05).The Lysholm score in the treatment and control group were (88.87 ± 6.33) points and (76.13 ± 5.98) point,significantly higher than before operation ((44.23 ± 4.29) points and (44.67 ± 5.13) point;t =14.875,8.113;P<0.05).The incidence of adverse events during the treatment in the treatment group and the control group were 8.8%(6/68) and 13.2%(9/68) respectively,there was no significant differemce between the two groups (x2 =0.391,P>0.05).All adverse reactions after symptomatic treatment were improved.Conclusion Sodium hyaluronate combined arthroscopic joint clean-up surgery for the patellofemoral arthritis knee pain patients can effectively play the role of promoting the knee pain and function,and has good efficacy and safety,and is worth popularizing and applying.
RESUMEN
Determinar qué porcentaje de una población sin dolor anterior de rodilla tiene un test de Zohlen positivo, además determinar el ángulo Q de esta población y buscar si existe alguna relación entre la positividad del test de Zohlen y alteraciones en el ángulo Q. Material y método: Estudio descriptivo-prospectivo observacional. Aplicación del test de Zohlen y medición del ángulo Q. La población se dividió en 2 grupos: test de Zohlen positivo y test de Zohlen negativo. Cuantificación y comparación de medias del ángulo Q en los dos grupos. Resultados: 90 sujetos evaluados, promedio de edad 20,18 años (18-40). Veinte sujetos (22,2 por ciento) con test de Zohlen positivo. Ángulo Q promedio en los sujetos con test de Zohlen negativo: 14,95°; ángulo Q promedio en los sujetos con test de Zohlen positivo: 16,9° (p < 0,05). Ángulo Q promedio en hombres con test de Zohlen negativo 13,4°; ángulo Q promedio en hombres con test de Zohlen positivo: 16° (p < 0,05). Ángulo Q promedio en mujeres con test de Zohlen negativo: 16,5°; ángulo Q promedio en mujeres con test de Zohlen positivo: 18°, sin diferencias estadísticamente significativas entre ambos grupos. Conclusiones: El test de Zohlen tiene una correlación positiva con el ángulo Q en sujetos de sexo masculino. Dada la correlación entre un ángulo Q alterado y la presencia de dolor anterior de rodilla, en los pacientes que presentan un test de Zohlen positivo sin haber consultado por dolor anterior de rodilla, la prevención primaria de dolor anterior de rodilla puede ser de utilidad...
To determine the percentage of a population without anterior knee pain with a positive Zohlen test, and also to determine the Q angle of this population and to determine if there is any relationship between the Zohlen test and Q angle anomalies. Methods:A prospective observational study was conducted in which Zohlen¿s test was applied and the Q angle was measured. The population was divided into 2 groups: Zohlen¿s positive and Zohlen¿s negative. Q angle was compared in the 2 groups. Results: The study included 90 subjects, with a mean age 20.18 years (18-40), of whom 20 subjects (22.2 percent) had positive Zohlen¿s test. The mean Q angle in subjects with negative Zohlen¿s test was 14.95°, and the mean Q angle in subjects with positive Zohlen¿s test was 16,9° (p<.05). The mean Q angle in men with negative Zohlen¿s test was 13.4°, and the mean Q angle in men with positive Zohlen¿s test was 16° (p < .05). The mean Q angle in women with negative Zohlen¿s test was 16.5°, with a mean Q angle of 18° in women with positive Zohlen¿s test, with no statistically significant differences found between groups. Conclusions: Zohlen¿s test has a positive correlation with the Q angle in male subjects. Given the correlation between the Q angle and the presence of anterior knee pain in patients who have a positive test without symptoms, primary prevention of anterior knee pain can be achieved...

Objective The purpose of this investigation was to discuss the relationship between the rotation of lower extremity biomechanics and patellofemoral pain(PFP) .Methods With normal volunteers as controls ,patients with PFP were scanned by ul‐trathin CT ,keeping the bilateral lower extremity straight neutral .The anatomy parameters were measured and analysed ,such as femoral neck anteversion(FNA) ,femoral neck shaft angle(NSA) ,posterior condylar angle(PCA) ,femoral rotation relative to tibia (FRRT) ,tibial torsion angle(TTA) and patella tilt angle(PTA) .Results Compared with control group ,the PFP group FNA ,FR‐RT ,PCA ,TTA and PTA increase statistically significant (P0 .05) .It could be found that PTA had the most obvious influence on the VAS score ,followed by FNA and TTA ;and PTA had the most obvious influence on the WOMAC function score ,followed by TTA ;and significant negative correlation could be found between PTA and age (r= -0 .548 ,P<0 .05) .Conclusion PTA is a sensitive indicator to assess VAS score and WOMAC function score for individ‐uals with PFPS .Increases of PTA ,FNA ,PCA ,FRRT and TTA are associated with PFP for women .
RESUMEN
PURPOSE: The purpose of this study was to evaluate the clinical effect of electrocautery on the reduction of pain in patellar non-resurfacing bilateral total knee arthroplasty. MATERIALS AND METHODS: A total of 50 patients were enrolled into this study; all patients had undergone bilateral patellar non-resurfacing total knee arthoplasty at our hospital, between January 2007 to December 2008. The minimum follow-up period was 1 year. The electrocautery of the patellar rim was performed randomly on one side only. The clinical results were evaluated between the electrocautery group and the non-electrocautery group based on measures of anterior knee pain, range of motion, American Knee Society clinical rating score, Feller knee score, Western Ontario and McMaster Universities score, and radiographic analysis. RESULTS: There were statistically significant differences between preoperative and postoperative status for all parameters. There were no statistically significant differences noted between the electrocautery group and the non electrocautery group for all parameters. CONCLUSIONS: Electrocautery of patellar rim is thought to be less effective in reducing anterior knee pain.
