Abstract
Background: Primary gonarthrosis is a progressive disease that increases with age and leads to limitations in activities of daily living. Until surgery is performed, nonsteroidal anti-inflammatory drugs, intraarticular injections, and physical therapy methods are used.
Purpose: This study aims to compare the clinical outcomes of intra- articular corticosteroid (CCS) and hyaluro nic acid (HA) injections for pain relief in primary gonartrhosis in COVID -19 pandemic period.
Study Design: Retrospective Cohort Study.
Methods: In this study, 88 patients who underwent intra-articular CCS and HA injection between August 2020 and March 2021 due to Kellgren-Lawrence stage 2 and higher gonarthrosis were investigated. Patients were divided into two groups. Group I represents the patients who received HA injections, and group II represents the patients who received CCS injection. Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Knee Society Score (KSS) scores were used for the preoperative and postoperative functional evaluations of the patients.
Results: Group I included 40 patients and group II included 48 patients. The mean age was 59.4 ± 7.3 years, and the average follow-up period was 12 ± 2,6 months. The pre-intervention WOMAC scores were 13,5 in Group I and 13.6 in Group II, KSS scores were 26,5 in Group I and 25,2 in Group II. While there was a significant change in the control at month 1 in both groups, no difference was found between the groups. At the 6th month control, the improvement in group 1 continued at a significant level compared to the pre-injection period, while group 2 returned to the pre-injection level. (p

Females with knee osteoarthritis use a detrimental knee loading strategy when squatting. Knee 2022; 38:9-18. [PMID: 35868143 DOI: 10.1016/j.knee.2022.05.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Revised: 04/27/2022] [Accepted: 05/25/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND The purpose of this study was to identify sex differences in lower limb kinematics, kinetics, and muscle activation patterns between individuals with osteoarthritis and healthy controls during a two-legged squat. METHOD Thirty OA (15 females) and 30 healthy (15 females) participants performed three 2-legged squats. Sagittal and frontal plane hip, knee, and ankle kinematics and kinetics were calculated. Two-way ANOVAs (Sex X OA Status) were used to characterize differences in squatting strategies between sexes and between those with and without knee OA. RESULTS A greater decrease in sagittal hip, knee, and ankle range of motion and knee joint power was observed in the OA participants compared to the healthy controls. Females with OA had significantly reduced hip and knee adduction angles compared to the healthy females and males with OA. Females also had decreased hip power, hip flexion, and hip adduction moments and knee adduction moments compared to their male counterparts, with the greatest deficits observed in the females with OA. Females with OA also had the highest magnitude of muscle activation for the quadriceps, hamstrings, and gastrocnemius throughout the squat, while males with OA showed increased activation of the vastus lateralis and medial gastrocnemius compared to the healthy males. CONCLUSIONS OA significantly altered biomechanics and neuromuscular control during the squat, with males employing a hip-dominant strategy, allowing them to achieve a greater lower limb range of motion.

Mild radiographic osteoarthritis is associated with increased pain and dissatisfaction following total knee arthroplasty when compared with severe osteoarthritis: a systematic review and meta-analysis. Knee Surg Sports Traumatol Arthrosc 2022; 30:965-981. [PMID: 33604736 DOI: 10.1007/s00167-021-06487-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2020] [Accepted: 02/01/2021] [Indexed: 10/22/2022]
Abstract
PURPOSE The association between severity of radiographic osteoarthritis with patient pain, function, and satisfaction following total knee arthroplasty has been disputed. The discrepancies in current literature prompt us to further examine this association in a systematic review and meta-analysis. METHODS The OVID-Medline, Embase, and Web of Science databases were searched from their inception up to Mar 2020. The main independent variable was osteoarthritis severity as defined by preoperative radiographs. The outcomes measured were pain, function and satisfaction following total knee arthroplasty. A minimum of three studies assessing the same patient-reported outcome measures were included in the meta-analysis, as well as those separating patients by chronic pain or dissatisfaction. RESULTS 29 studies were included in this study. Significant heterogeneity was seen between radiographic evaluation and reported outcomes. Patients with only mild radiographic osteoarthritis were more likely to suffer from chronic pain (odds ratio = 2.45, 95% CI = 1.80-3.34, p < 0.001) and dissatisfaction (odds ratio = 2.43, 95% CI = 1.79-3.31, p < 0.001) compared to patients with severe osteoarthritis. A significant association was found between mild radiographic severity and lower total Western Ontario and McMaster Universities Osteoarthritis scores (95% CI = - 0.37-0.06, p = 0.006) as well as Knee Society Scores (CI: - 0.54-0.16, p < 0.001). CONCLUSION Patients with mild radiographic osteoarthritis are anticipated to gain less from total knee arthroplasty compared to those with severe osteoarthritis. They are also at risk for chronic pain and dissatisfaction and should be consulted about this risk prior to surgery. LEVEL OF EVIDENCE III.

A Comparison Between Low-Level Laser Therapy and Intra-articular Ozone Injection in Knee Osteoarthritis Treatment: A Randomized Clinical Trial. J Lasers Med Sci 2021; 12:e44. [PMID: 34733767 DOI: 10.34172/jlms.2021.44] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2020] [Accepted: 02/02/2021] [Indexed: 01/05/2023]
Abstract
Introduction: Knee osteoarthritis (KOA) is a common degenerative joint disease, causing deformity, pain and a limited joint range of motion. Modification of the lifestyle and an exercise training program are the cornerstone of treatment. Alternative therapies such as laser or ozone are commonly used, but there is not any comparative study of low-level laser therapy (LLLT) versus ozone therapy. The aim of the study was to compare the efficacy and safety of the LLLT versus ozone in patients with KOA. Methods: In this single-blinded randomized clinical trial, 60 patients with KOA were assigned to LLLT or ozone groups (n=30). The First basic pain severity, the Western Ontario and McMaster Universities Arthritis Index (WOMAC) score and physical function were determined. Then in the LLLT group, the patients were provided with 12 sessions of LLLT. In the ozone group, 6 sessions of intra-articular injection of ozone were organized (in each session a mixture of 10 mL of bupivacaine 0.25% with 15 mL of ozone 30 μg/mL). In the middle and at the end of the intervention period, we reassessed the joint pain and physical function and the degree of improvement compared between the two groups. Results: In the middle and at the end of the treatment period in both groups, the joint pain decreased significantly. The same as pain, the self-administrated WOMAC score and the range of joint motion improved significantly in both groups. All of these variables exposed more improvement in the ozone group patients. Conclusion: The study showed that both LLLT and ozone are acceptable non-invasive methods in the non-surgical treatment of KOA. Compared to LLLT, the ozone was more effective. These methods must be considered in any patient who is not suitable for surgical interventions or does not experience enough improvement in symptoms following long periods of common exercise training programs.

Abstract
Abstract
Background
Osteoarthritis (OA) is a degenerative disease which presents with joint pain and stiffness and reduced mobility. Knee OA is the commonest cause of disability in adults. Dextrose prolotherapy is a new option used to treat mild-to-moderate knee OA. Neural prolotherapy (NPT) is multiple small injections under the skin targeting painful areas with natural substances. The aim of work was to evaluate and compare neural prolotherapy versus intra-articular dextrose prolotherapy effect on relieving pain and improving disability of knee OA.
Results
VAS and WOMAC scores improved significantly immediately and at 3 and at 6 months, respectively, in group I compared with group II (P < 0.001). The decrease in VAS scores and all the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores in group I along the follow-up period in comparison with the baseline scores was statistically significant (P < 0.001). In group II, only WOMAC pain and stiffness scores improved significantly. ROM showed insignificant increase in both groups at 3 and 6 months assessment. On follow-up, range of motion increased in both groups and reached significance in group I (P = .002).
Conclusion
Dextrose prolotherapy both intra-articular and periarticular (neural) is a very effective and cheap therapy for knee OA with good patient selection. Neural prolotherapy significantly relieves pain and improves function in patients with knee osteoarthritis when compared with intra-articular prolotherapy thus avoiding hazards of intra-articular knee injections.

Pain interference may be an important link between pain severity, impairment, and self-reported disability in participants with wrist/hand pain. J Hand Ther 2021; 33:562-570.e1. [PMID: 31481341 DOI: 10.1016/j.jht.2019.06.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Revised: 06/09/2019] [Accepted: 06/18/2019] [Indexed: 02/03/2023]
Abstract
STUDY DESIGN Cross-sectional. INTRODUCTION Pain severity, sensory and motor impairment, and psychological (distress and anxiety) and social factors have previously been related to self-reported disability in persons with wrist and hand pain. PURPOSE OF THE STUDY The purpose of this study to determine the relative contribution of pain severity, measures of impairment (sensory and motor function), psychosocial factors, and pain interference on self-reported disability experienced by persons with heterogeneous orthopedic injuries and conditions of the wrist and hand. METHODS Measures of disability and pain severity as well as measures of sensory (pressure pain thresholds, joint position sense), motor (grip strength, Purdue pegboard), and cognitive performance (Stroop test) and psychosocial variables related to pain and participation (West Haven-Yale Multidimensional Pain Inventory) were administered to 60 participants with wrist and hand pain. Pearson product correlations controlled for age and sex, and multiple linear regression was performed to determine the relationship between measures of impairment, pain severity, psychosocial variables, and pain interference with self-reported disability assessed with the Disability of Arm, Shoulder and Hand (DASH) questionnaire. RESULTS The best-fitting regression model with DASH scores entered as the dependent variable (F4,50 = 28.8, P < .01) included MPI Pain Interference (β = -0.54), Life Control (β = -0.16), Purdue pegboard scores (β = -0.32), and Stroop test times (β = 0.21). Pain Interference had the strongest correlation with self-reported disability (adjusted R2 = 0.67, P < .01). CONCLUSION Pain interference appears to be an important factor explaining the link between impairment, pain severity, and self-reported disability. Addressing pain interference may be important to improve outcomes in this population.

Abstract
OBJECTIVE To evaluate an effectiveness of a single intra-articular injection of a new cross-linked hyaluronic acid by measuring thickness of the quadriceps muscle and femoral intercondylar cartilage in addition to subjective assessment. MATERIAL AND METHODS There were 49 patients with gonarthrosis (Kellgren-Lawrence grade II-III) who underwent a single intra-articular injection of Flexotron Cross into the knee joint with higher grade of arthrosis. The scores were assessed at baseline, after 1, 3 and 6 months using: 1) visual analogue scale (VAS) of pain syndrome, 2) Western Ontario and McMaster University Osteoarthritis Index (WOMAC), 3) Lequesne Index, 4) duration of standing on one leg, 5) thigh circumference, 6) thickness of quadriceps muscle and femoral intercondylar cartilage according to ultrasound data. RESULTS A 6-month follow-up comprised 46 patients. HA administration significantly improved all parameters (p <0.001). VAS and WOMAC pain scores were significantly improved after 1, 3 and 6 months (p <0.01). Thickness of the quadriceps muscle and femoral intercondylar cartilage was increased after 3 and 6 months (p <0.05). Lequesne Index, duration of standing on one leg and thigh circumference were also increased in 6 months after HA administration (p <0.01). CONCLUSION Flexotron Cross is effective subjectively and objectively for at least 6 months and safe for the treatment of gonarthrosis.

Hyaluronan suppresses enhanced cathepsin K expression via activation of NF-κB with mechanical stress loading in a human chondrocytic HCS-2/8 cells. Sci Rep 2020; 10:216.

Abstract
Cathepsin K is a protease known to be involved in not only bone remodeling and resorption, but also articular cartilage degradation that leads to osteoarthritis (OA). Hyaluronan (HA) plays a pivotal role in maintaining homeostasis within articular chondrocytes. Intra-articular supplementation of high molecular weight hyaluronan (HMW-HA) has been widely used in OA treatment. However, its prospective mechanism of action is still unclear. In this study, we examined the suppressive effect of HA on enhanced cathepsin K expression induced by mechanical stress loading. A human chondrocytic HCS-2/8 cells were cultured in silicon chambers and subjected to cyclic tensile stress (CTS) loading. CTS loading significantly increased messenger ribonucleic acid and protein expression of cathepsin K, which appeared to be suppressed by pre-treatment with HMW-HA. Activation of nuclear factor-kappa B (NF-κB) was induced by CTS loading, and suppressed by pre-treatment with HMW-HA. Helenalin, a chemical inhibitor of NF-κB, clearly suppressed the enhanced expression of cathepsin K, as well as NF-κB activation induced by CTS loading. The suppressive effect of HMW-HA on enhanced cathepsin K expression via NF-κB inhibition impacts the effectiveness of HMW-HA in OA treatment. Our findings provide new evidence supporting the biological effectiveness of intra-articular HMW-HA injections for treatment of OA.

Abstract
The study aimed to investigate the effects of 24 weeks Taichi intervention on knee and ankle proprioception amongst individuals with knee osteoarthritis (KOA). Ninety-two patients with KOA were included in the current study, involving 52 participants in the intervention group and 40 participants in the control group. The intervention group performed Taichi exercise for 24 weeks, the control group accepted the health education lectures. The main outcome of this study was the proprioception of the knee and ankle which was measured by an electric-driven movable frame. Between- and within-group differences were evaluated through the repeated-measurement ANOVA. For the Taichi group, the differences in the changes in ankle proprioception were significant on ankle plantarflexion (p = 0.03), ankle dorsiflexion (p = 0.043), ankle varus (p = 0.019) and knee flexion (p = 0.01) between the baseline and post-test measures. Twenty-four weeks Taichi exercise may improve the ankle and knee proprioception of patients with KOA.

Abstract
Introduction Osteoarthritis (OA) is the single-most common cause of physical disability among adults. In view of its promising management modalities, an analysis of the level of awareness among the suspected individuals and their attitudes is crucial to assess the level of their implementation. This study aimed to do that among the female population in Karachi, Pakistan. Methods This cross-sectional study was conducted among 316 elderly females (≥60 years) in Karachi in 2018. Data were collected via a structured questionnaire, which included sections titled: demographics, knowledge, attitudes, and practices. Data were analyzed using the Statistical Package for Social Sciences (version 20.20, IBM, Armonk, New York, US), and chi-square tests were used to assess the connection between OA care and socioeconomic statuses. Mean and standard deviation were calculated for quantitative variables. Results A considerable portion (48%, n = 152) of the participants were from a lower socioeconomic background, and 51% of them had a history of joint pain. Significantly, 63% of the participants (n = 199) attributed their joint pain to age, while nearly half attributed it to their diet and exercise habits. A major segment (73%, n = 230) of the participants, irrespective of their socioeconomic backgrounds, had visited a doctor for their joint complaints. Around 65% of the participants said they would never undergo a knee-joint replacement, regardless of how worse their symptoms might get. Additionally, 36% of the participants were unsatisfied with their current treatment, while more than half of the participants said that medication would improve their condition. Conclusions Our results demonstrate a connection between the lack of awareness about OA and the factors negatively affecting its management. They also point towards areas that require focused efforts for better awareness.

Abstract
Osteoarthritis (OA) is a chronic multifactorial disease characterized by progressive joint degeneration. The purpose of this study was to compare the effects of ultrasound-guided corticosteroid injection with oxygen-ozone injection in patients with knee OA. This double-blind randomized clinical trial was performed on 62 patients with knee OA. The patients were randomly divided into two groups. In the first group 40 mg triamcinolone (1 cc) and in the second group 10 cc (15 μg/ml) oxygen-ozone (O2-O3) were injected into the knee joint under ultrasound guidance. Outcome measures included the Western Ontario and McMaster Universities Osteoarthritis (WOMAC), knee flexion range of motion (ROM), effusion in ultrasound images of the suprapatellar recess, and visual analog scale (VAS), which were evaluated before injection, 1 week, 1 month, and 3 months after the treatment. Sixty-two patients (10 men and 52 women) were enrolled with mean age of 57.9 years. VAS improved in both groups (steroid P value = 0.001, oxygen-ozone P value > 0.001). The improvements seen in VAS and WOMAC scores 3 months after treatment were in favor of the oxygen-ozone group when compared to the steroid group (P = 0.041 vs P = 0.19). There was no significant difference between the two groups in ROM and joint effusion seen under ultrasound (ROM p = 0.880, effusion p = 0.362). However, in the oxygen-ozone-receiving group, joint effusion was decreased significantly (p < 0.001). Both steroid and oxygen-ozone injections are effective in patients with knee osteoarthritis. Our study showed that the effects of oxygen-ozone injection last longer than those of steroid injection to the knee joint.

Abstract
BACKGROUND AND AIMS Traditional Chinese exercise (TCE) includes a variety of exercise, which is being accepted by more and more people in the treatment of knee osteoarthritis (OA) from different countries. With the attendant, many clinical reports focus on it. Our meta-analysis aimed to systematically assess the effects of traditional Chinese exercise on pain, stiffness, physical function, quality of life, mental health and adverse events in people with knee osteoarthritis. METHODS PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), the Web of Science, and Chinese Biomedical Literature Database (CBM) were searched from the time of their inception through April 2016 and risk of bias was independently assessed by two authors. Outcome measures included pain, physical functional, joint stiffness, quality of life, mental health and safety. For pooled outcomes, standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated. RESULTS Eight randomized controlled trials with a sample size of 375 cases met the criteria to be included in the study indicating that high quality literature is lacking in this field. Results of the meta-analysis showed that short-term TCE could relieve pain (SMD: -0.77;95% CI: -1.13 to -0.41; P<0.0001), improve physical function (SMD -0.75; 95% CI: -0.98 to -0.52; P<0.00001), and alleviate stiffness (SMD: -0.56; 95%: CI -0.96 to -0.16; P<0.006), but had no significant effect on quality of life (SMD: 0.57; 95% CI: 0.17 to 0.97; P = 0.005), and mental health (SMD 4.12; 95% CI: -0.50 to 8.73; P = 0.08). Moreover, TCE was not associated with serious adverse events. CONCLUSIONS Our systematic review revealed that short-term TCE was potentially beneficial in terms of reducing pain, improving physical function and alleviating stiffness. These results may suggest that TCE could prove useful as an adjuvant treatment for patients with knee OA. Further studies are urgently needed to confirm these results.

Abstract
Though walking impairments are prevalent in society, clinical treatments are often ineffective at restoring lost function. For this reason, researchers have begun to explore the use of patient-specific computational walking models to develop more effective treatments. However, the accuracy with which models can predict internal body forces in muscles and across joints depends on how well relevant model parameter values can be calibrated for the patient. This study investigated how knowledge of internal knee contact forces affects calibration of neuromusculoskeletal model parameter values and subsequent prediction of internal knee contact and leg muscle forces during walking. Model calibration was performed using a novel two-level optimization procedure applied to six normal walking trials from the Fourth Grand Challenge Competition to Predict In Vivo Knee Loads. The outer-level optimization adjusted time-invariant model parameter values to minimize passive muscle forces, reserve actuator moments, and model parameter value changes with (Approach A) and without (Approach B) tracking of experimental knee contact forces. Using the current guess for model parameter values but no knee contact force information, the inner-level optimization predicted time-varying muscle activations that were close to experimental muscle synergy patterns and consistent with the experimental inverse dynamic loads (both approaches). For all the six gait trials, Approach A predicted knee contact forces with high accuracy for both compartments (average correlation coefficient r = 0.99 and root mean square error (RMSE) = 52.6 N medial; average r = 0.95 and RMSE = 56.6 N lateral). In contrast, Approach B overpredicted contact force magnitude for both compartments (average RMSE = 323 N medial and 348 N lateral) and poorly matched contact force shape for the lateral compartment (average r = 0.90 medial and -0.10 lateral). Approach B had statistically higher lateral muscle forces and lateral optimal muscle fiber lengths but lower medial, central, and lateral normalized muscle fiber lengths compared to Approach A. These findings suggest that poorly calibrated model parameter values may be a major factor limiting the ability of neuromusculoskeletal models to predict knee contact and leg muscle forces accurately for walking.

Abstract
Increased vascular endothelial growth factor (VEGF) levels are associated with osteoarthritis (OA) progression. Indeed, VEGF appears to be involved in OA-specific pathologies including cartilage degeneration, osteophyte formation, subchondral bone cysts and sclerosis, synovitis, and pain. Moreover, a wide range of studies suggest that inhibition of VEGF signaling reduces OA progression. This review highlights both the potential significance of VEGF in OA pathology and pain, as well as potential benefits of inhibition of VEGF and its receptors as an OA treatment. With the emergence of the clinical use of anti-VEGF therapy outside of OA, both as high-dose systemic treatments and low-dose local treatments, these particular therapies are now more widely understood. Currently, there is no established disease-modifying drug available for patients with OA, which warrants continued study of the inhibition of VEGF signaling in OA, as stand-alone or adjuvant therapy. © 2016 American Society for Bone and Mineral Research.

Abstract
PURPOSE To examine the effect of obesity and its potential interaction with knee OA presence on the electromyography patterns of the major knee joint periarticular muscles during walking. SCOPE One hundred and eighteen asymptomatic adults and 177 adults with moderate knee osteoarthritis were subdivided into categories of healthy weight (n = 77; 20 kg/m(2) < BMI < 25 kg/m(2)), overweight (n = 117; 25 kg/m(2) ⩽ BMI < 30 kg/m(2)), and obese (n = 101; BMI ⩾ 30 kg/m(2) based on their body mass index (BMI). All individuals underwent a three-dimensional gait analysis. Surface electromyograms from the lateral and medial gastrocnemii, lateral and medial hamstrings, vastus lateralis, vastus medialis, and rectus femoris were recorded during self-selected speed walking. Principal component analysis was used to extract major features of amplitude and temporal pattern variability from the electromyograms of each muscle group (gastrocnemii, quadriceps, hamstrings separately). Analysis of variance models tested for main BMI category effects and interaction effects for these features (α = 0.05). Statistically significant BMI category (i.e. obesity) effects were found for features that described more prolonged activations of the gastrocnemii and quadriceps muscles during the stance phase of gait with obesity (P < 0.05). CONCLUSIONS Obesity was associated with prolonged activation of quadriceps and gastrocnemii, which can result in prolonged knee joint contact loading, and thereby may contribute to the predisposition of knee OA development and progression in obese individuals.

Abstract
Background: Knee osteoarthritis (KOA) is a common disabling disease. Limited studies have demonstrated that prolotherapy with dextrose or with prolozone can be helpful in the treatment of patients with KOA. Objectives: In the current study, we compared the results between these two treatment methods. Patients and Methods: In the current randomized clinical trial, 80 patients with mild to moderate KOA were randomly assigned equally into two groups (ozone group and dextrose group). In each group, injections were repeated three times with 10-day intervals. Before the treatment and 3 months after the injections, the pain intensity was measured by using a visual analogue scale and the Western Ontario and McMaster university arthritis index scores. Finally, the results were compared between the two groups. Results: In the two groups, the pain intensity and WOMAC scores significantly decreased and increased, respectively (P < 0.001). However, there was no significant difference between the two groups. Conclusions: Prolotherapy with dextrose and with prolozone result in the same pain relief or functional improvement in patients with mild to moderate KOA.

The effect on knee-joint load of instruction in analgesic use compared with neuromuscular exercise in patients with knee osteoarthritis: study protocol for a randomized, single-blind, controlled trial (the EXERPHARMA trial). Trials 2014; 15:444.

Abstract
BACKGROUND Knee osteoarthritis (OA) is a mechanically driven disease, and it is suggested that medial tibiofemoral knee-joint load increases with pharmacologic pain relief, indicating that pharmacologic pain relief may be positively associated with disease progression. Treatment modalities that can both relieve pain and reduce knee-joint load would be preferable. The knee-joint load is influenced by functional alignment of the trunk, pelvis, and lower-limb segments with respect to the knee, as well as the ground-reaction force generated during movement. Neuromuscular exercise can influence knee load and decrease knee pain. It includes exercises to improve balance, muscle activation, functional alignment, and functional knee stability. The primary objective of this randomized controlled trial (RCT) is to investigate the efficacy of a NEuroMuscular EXercise (NEMEX) therapy program, compared with optimized analgesics and antiinflammatory drug use, on the measures of knee-joint load in people with mild to moderate medial tibiofemoral knee osteoarthritis. METHOD/DESIGN One hundred men and women with mild to moderate medial knee osteoarthritis will be recruited from general medical practices and randomly allocated (1:1) to one of two 8-week treatments, either (a) NEMEX therapy twice a week or (b) information on the recommended use of analgesics and antiinflammatory drugs (acetaminophen and oral NSAIDs) via a pamphlet and video materials. The primary outcome is change in knee load during walking (the Knee Index, a composite score of the first external peak total reaction moment on the knee joint from all three planes based on 3D movement analysis) after 8 weeks of intervention. Secondary outcomes include changes in the external peak knee-adduction moment and impulse and functional performance measures, in addition to changes in self-reported pain, function, health status, and quality of life. DISCUSSION These findings will help determine whether 8 weeks of neuromuscular exercise is superior to optimized use of analgesics and antiinflammatory drugs regarding knee-joint load, pain and physical function in people with mild to moderate knee osteoarthritis.

Abstract
PURPOSE Although arthritis is the leading cause of pain and disability in Canada, and physical therapy (PT) and occupational therapy (OT) are beneficial both for chronic osteoarthritis (OA) and for inflammatory arthritis such as rheumatoid arthritis (RA), there appear to be problems with access to such services. The aim of this study was to document wait times from referral by physician to consultation with PT or OT in the public health care system for people with arthritis in Quebec, Canada. METHOD Appointments were requested by telephone, using hypothetical case scenarios; wait times were defined as the time between initial request and appointment date. Descriptive statistics were used to examine the wait times in relation to diagnosis, service provider and geographic area. RESULTS For both scenarios (OA and RA) combined, 13% were offered an appointment within 6 months, 13% offered given an appointment within 6-12 months, 24% were told they would need to wait longer than 12 months, and 22% were refused services. The remaining 28% were told they would require an evaluation appointment for functional assessment before being given an appointment for therapy. No difference was found between RA and OA diagnoses. CONCLUSIONS Our study suggests that most people with arthritis living in the province of Quebec are not receiving publicly accessible PT or OT intervention in a timely manner.

Abstract
AIM To compare tissue concentrations of flurbiprofen resulting from topical application and oral administration according to the regulatory approved dosing guidelines. METHOD Sixteen patients were included in this study. Each patient was randomly assigned to the topical application or oral administration group. In each group, a pair of tapes or a tablet, containing a total of 40 mg flurbiprofen, was administered twice at 16 and 2 h before the surgery. RESULTS The flurbiprofen concentration in the fat, tendon, muscle and periosteum tissues was significantly higher (P < 0.0330) after topical application (992 ng g⁻¹ [95% CI 482, 1503], 944 [95% CI 481, 1407], 492 [95% CI 248, 735], and 455 [95% CI 153, 756], respectively) than after oral administration (150 ng g⁻¹ [95% CI 84, 217], 186 [95% CI 118, 254], 82 [95% CI 49, 116],and 221 [95% CI, 135, 307], respectively). CONCLUSION Topical application is an effective method to deliver flurbiprofen to the human body, particularly to soft tissues near the body surface.

Abstract
OBJECTIVE To examine whether there was a dose response for valgus unloader brace wear on knee pain, function, and muscle strength in participants with medial compartment knee osteoarthritis. DESIGN In this single-group study, participants with medial compartment knee osteoarthritis were followed for approximately 6 months. SETTING Recruitment was conducted in the general community, and testing was performed at a university laboratory. PARTICIPANTS A convenience sample of patients (N=32) who were prescribed a valgus unloader brace agreed to participate, met the inclusion criteria, and completed the baseline data collection. Twenty-four participants (20 men, 4 women) completed baseline and follow-up collections. INTERVENTION Participants wore their valgus unloader brace as needed. MAIN OUTCOME MEASURES Knee extensor, flexor, and plantar flexor strength was tested at baseline and follow-up. Participants filled out Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Medical Outcomes Study 36-Item Short-Form Health Survey questionnaires to assess pain and function. Self-selected walking velocity and stride length were objective measures of function. Brace usage (dose) and activity (step count) were recorded at least 4 days/week for the study duration. RESULTS Positive relationships existed between brace wear usage and percent change in step count (r=.59, P=.006) and percent change in hamstrings strength (r=.37, P=.072). At follow-up, there was significant improvement in hamstrings strength (P=.013), and trends toward improvements in WOMAC pain (P=.059) and WOMAC function (P=.089). CONCLUSIONS Our results indicate that greater brace use may positively affect physical activity level, but there was minimal effect of brace wear dosage on lower-limb muscle strength. Only knee flexion showed a positive relationship. Our finding of no decreased muscle strength indicates that increased brace use over a 6-month period does not result in muscle impairment.

Abstract
Background Osteoarthritis of the knee involving predominantly the medial tibiofemoral compartment is common in older people, giving rise to pain and loss of function. Many people experience progressive worsening of the disease over time, particularly those with varus malalignment and increased medial knee joint load. Therefore, interventions that can reduce excessive medial knee loading may be beneficial in reducing the risk of structural progression. Traditional quadriceps strengthening can improve pain and function in people with knee osteoarthritis but does not appear to reduce medial knee load. A neuromuscular exercise program, emphasising optimal alignment of the trunk and lower limb joints relative to one another, as well as quality of movement performance, while dynamically and functionally strengthening the lower limb muscles, may be able to reduce medial knee load. Such a program may also be superior to traditional quadriceps strengthening with respect to improved pain and physical function because of the functional and dynamic nature. This randomised controlled trial will investigate the effect of a neuromuscular exercise program on medial knee joint loading, pain and function in individuals with medial knee joint osteoarthritis. We hypothesise that the neuromuscular program will reduce medial knee load as well as pain and functional limitations to a greater extent than a traditional quadriceps strengthening program. Methods/Design 100 people with medial knee pain, radiographic medial compartment osteoarthritis and varus malalignment will be recruited and randomly allocated to one of two 12-week exercise programs: quadriceps strengthening or neuromuscular exercise. Each program will involve 14 supervised exercise sessions with a physiotherapist plus four unsupervised sessions per week at home. The primary outcomes are medial knee load during walking (the peak external knee adduction moment from 3D gait analysis), pain, and self-reported physical function measured at baseline and immediately following the program. Secondary outcomes include the external knee adduction moment angular impulse, electromyographic muscle activation patterns, knee and hip muscle strength, balance, functional ability, and quality-of-life. Discussion The findings will help determine whether neuromuscular exercise is superior to traditional quadriceps strengthening regarding effects on knee load, pain and physical function in people with medial knee osteoarthritis and varus malalignment.

Abstract
PURPOSE The number of effective knee osteoarthritis (OA) interventions, especially those tailored to specific compartmental involvement, are small. The objective of this study was to determine the efficacy of a realigning patellofemoral (PF) brace in improving pain and function among persons with symptomatic lateral PF OA. METHOD We conducted a double blind, randomized crossover trial of a realigning PF brace for persons with lateral PF OA. Participants had lateral PF OA with anterior knee symptoms on most days of the month, lateral PF joint space narrowing, and radiographic evidence of a definite osteophyte in the PF joint. We compared two treatments: (1) Control treatment consisting of a BioSkin Q Brace with patellar realigning strap removed; and (2) Active treatment consisting of a realigning BioSkin Q Brace with the strap applied. For each participant, the trial lasted 18 weeks, including 6 weeks each of active and control treatment period separated by a 6-week washout period. The order of treatments was randomized. The primary outcome was change in knee pain on the visual analog scale (VAS). Secondary outcomes included WOMAC pain, function, and stiffness. An unstructured correlation matrix for observations within participants was used in generalized estimating equation fitting to derive a linear regression model that expressed the relation between the intervention and change in VAS pain. RESULTS 80 participants (63 F) with a mean age and body mass index of 61 years and 28 kg/m(2), respectively, were randomized by order of treatment. A model examining the main effects for change in VAS knee pain (0-100) demonstrated no significant treatment effect (-0.68 VAS units, 95% CI: -6.2, 4.8 units, P=0.81) and no differential carryover effect. There was also no significant difference between active and control treatments for WOMAC pain, function, or stiffness outcomes. CONCLUSION The effects of a specific realigning PF brace are not of clinical or statistical significance.

Abstract
Interleukin-1 beta (IL1β) is a proinflammatory cytokine that mediates arthritic pathologies. Our objectives were to evaluate pain and limb dysfunction resulting from IL1β over-expression in the rat knee and to investigate the ability of local IL1 receptor antagonist (IL1Ra) delivery to reverse-associated pathology. IL1β over-expression was induced in the right knees of 30 Wistar rats via intra-articular injection of rat fibroblasts retrovirally infected with human IL1β cDNA. A subset of animals received a 30 µl intra-articular injection of saline or human IL1Ra on day 1 after cell delivery (0.65 µg/µl hIL1Ra, n = 7 per group). Joint swelling, gait, and sensitivity were investigated over 1 week. On day 8, animals were sacrificed and joints were collected for histological evaluation. Joint inflammation and elevated levels of endogenous IL1β were observed in knees receiving IL1β-infected fibroblasts. Asymmetric gaits favoring the affected limb and heightened mechanical sensitivity (allodynia) reflected a unilateral pathology. Histopathology revealed cartilage loss on the femoral groove and condyle of affected joints. Intra-articular IL1Ra injection failed to restore gait and sensitivity to preoperative levels and did not reduce cartilage degeneration observed in histopathology. Joint swelling and degeneration subsequent to IL1β over-expression is associated limb hypersensitivity and gait compensation. Intra-articular IL1Ra delivery did not result in marked improvement for this model; this may be driven by rapid clearance of administered IL1Ra from the joint space. These results motivate work to further investigate the behavioral consequences of monoarticular arthritis and sustained release drug delivery strategies for the joint space.

Abstract
PURPOSE Physical and occupational therapy are beneficial for persons with chronic arthritis; however, access is problematic. The goal was to examine issues related to access to these services for patients with chronic arthritis. METHODS We used two data sources: 1) questionnaires sent to a random sample of 600 family physicians and to all 85 rheumatologists in the province of Quebec; and 2) interviews of 211 patients with physician-confirmed chronic arthritis recruited from 34 primary care settings in Quebec. RESULTS Only 11.5% of family physicians and 31.7% of rheumatologists referred patients with rheumatoid arthritis (RA) to rehabilitation, whereas 60.4% of family doctors referred patients with osteoarthritis. Only 26.1% of patients felt that they required rehabilitation and this was associated with lower self-efficacy (OR: 0.84, 95% CI: 0.72, 0.99) and higher educational level (OR: 2.10, 95% CI: 1.01, 4.36). CONCLUSION Family physicians are less likely to refer patients with RA to therapy. Only about a quarter of patients with chronic arthritis treated in primary care perceived the need for these services. Efforts to improve arthritis care should address education of physicians and patients regarding the benefits of rehabilitation and there should be efforts to increase therapy resources in order to enhance access.

Abstract
STUDY DESIGN Cross-sectional study. OBJECTIVE To compare functioning and disability in patients with hip osteoarthritis (OA) not candidates for surgery, to a matched control group, and thereby to examine the relationship between the functioning and disability components used in this study in patients with hip OA. BACKGROUND It is well known that patients with severe hip OA have deficits in functioning and disability. However, in patients with hip OA not candidates for surgery, the knowledge regarding functioning and disability is sparse. METHODS Twenty-six patients (12 men, 14 women; mean age, 60 years) with radiographic and symptomatic hip OA were matched to 26 controls without hip pain. The following variables were measured: muscle strength using isokinetic peak force, hip passive range of motion, submaximal aerobic capacity using a cycling test, walking ability using the 6-minute walk test, self-reported pain, stiffness, and physical function using the Western Ontario and McMaster University Osteoarthritis Index, and health-related quality of life using the SF-36. RESULTS The patients with hip OA had mild to moderate pain, as indicated by the Western Ontario and McMaster University Osteoarthritis Index, and significantly lower knee extension strength (mean difference [95% confidence interval {CI}]: -19.5 [-34.3, -4.7] Nm). Hip range of motion was significantly less in the patients with hip OA, with mean (95% CI) differences of -10° (-14°, -6°) for extension, -18° (-26°, -11°) for flexion, -9° (-14°, -4°) for abduction, -2° (-5°, 0°) for adduction, -16° (-23°, -9°) for internal rotation, and -21° (-28°, -14°) for external rotation. The patients with hip OA walked a significantly shorter distance in 6 minutes (mean difference, -75 m; 95% CI: -131, -20 m). There were no significant differences in hip extension/flexion, knee flexion, ankle dorsiflexion/plantar flexion muscle strength, or aerobic capacity between the 2 groups. There were significant associations between body function and activity components. CONCLUSION Physical therapists should consider including quadriceps-strengthening and hip range-of-motion exercises when developing rehabilitation programs for patients with hip OA, with mild to moderate pain, aiming to improve functioning and reduce disability.

Evaluation of the effects of a supplementary diet containing chicken comb extract on symptoms and cartilage metabolism in patients with knee osteoarthritis. Exp Ther Med 2010; 1:817-827.

Abstract
We aimed to investigate whether a supplementary diet containing chicken comb extract (CCE) rich in hyaluronic acid (HA) has an effect on pain and other symptoms, as well as cartilage type II collagen (CII) metabolism in patients with knee osteoarthritis (OA). A randomized double-blind placebo-controlled study was conducted in 43 subjects with knee OA (Kellgren/Lawrence grade, mainly 1-2) comprising 22 patients receiving concurrent exercise therapy (ET) and 21 without ET (referred as ET-receivers and ET-unreceivers, respectively). Subjects were randomized to a CCE-containing diet (active diet) group administered a dose of 1,800 mg/day (containing 630 mg of CCE and approximately 60 mg of HA) and a placebo group, and the intervention was continued for 16 weeks. Symptomatic efficacy was evaluated based on the Japanese Orthopaedic Association clinical trials response criteria (JOA response criteria) and Visual analog scales (VAS) before (baseline) and during the intervention. To further examine its effect on CII metabolism, the levels of two degradation biomarkers (CTX-II and C2C) and one synthesis biomarker (CPII) were measured using urine or serum samples. Nineteen subjects (10 ET-receivers and 9 ET-unreceivers) in the active diet group and 21 subjects (10 ET-receivers and 11 ET-unreceivers) in the placebo group were finally included in the study. Compared to the baseline, subscale scores of the JOA response criteria, i.e., 'pain/walking function', 'pain/step-up and -down function' and 'aggregate total symptoms' were more intensely improved in the active diet group than in the placebo group. Moreover, subgroup analyses of ET-receivers and ET-unreceivers indicated that significant improvements were restricted to ET-receivers of the active diet group. Furthermore, VAS assessment indicated that the 'pain on pressing' subscale was significantly improved in ET-receivers of the active diet group. In addition, analysis of CII biomarkers revealed that serum C2C and CPII levels, but not the urinary CTX-II level, were increased in the active diet group. Notably, both urinary CTX-II/serum CPII and serum C2C/serum CPII ratios were reduced in the active diet group (particularly ET-unreceivers), suggesting that CII synthesis was relatively increased compared to CII degradation in the active diet group. Finally, no diet-related side effects were observed. The CCE-containing diet is likely to be effective in relieving symptoms in patients with knee OA. In addition, it has the potential to improve the balance of CII degradation/synthesis in knee OA.

Abstract
Osteoarthritis (OA) is a degenerative joint disease that can result in joint pain, loss of joint function, and deleterious effects on activity levels and lifestyle habits. Current therapies for OA are largely aimed at symptomatic relief and may have limited effects on the underlying cascade of joint degradation. Local drug delivery strategies may provide for the development of more successful OA treatment outcomes that have potential to reduce local joint inflammation, reduce joint destruction, offer pain relief, and restore patient activity levels and joint function. As increasing interest turns toward intra-articular drug delivery routes, parallel interest has emerged in evaluating drug biodistribution, safety, and efficacy in preclinical models. Rodent models provide major advantages for the development of drug delivery strategies, chiefly because of lower cost, successful replication of human OA-like characteristics, rapid disease development, and small joint volumes that enable use of lower total drug amounts during protocol development. These models, however, also offer the potential to investigate the therapeutic effects of local drug therapy on animal behavior, including pain sensitivity thresholds and locomotion characteristics. Herein, we describe a translational paradigm for the evaluation of an intra-articular drug delivery strategy in a rat OA model. This model, a rat interleukin-1beta overexpression model, offers the ability to evaluate anti-interleukin-1 therapeutics for drug biodistribution, activity, and safety as well as the therapeutic relief of disease symptoms. Once the action against interleukin-1 is confirmed in vivo, the newly developed anti-inflammatory drug can be evaluated for evidence of disease-modifying effects in more complex preclinical models.

Abstract
BACKGROUND AND PURPOSE No detailed exercise programs specifically for patients with hip osteoarthritis (OA) have been described in the literature. This lack of data creates a gap between the recommendation that people with OA should exercise and the type and dose of exercises that they should perform. The purpose of this case report is to describe and demonstrate the use of a therapeutic exercise program for a patient with hip OA. CASE DESCRIPTION A 58-year-old woman with hip OA completed a 12-week therapeutic exercise program (TEP) with a 6-month follow-up. The patient reported hip pain, joint stiffness, and limited physical function, and she had decreased hip range of motion (ROM) at baseline. OUTCOMES The patient performed 19 sessions during the TEP, with a mean of 19.5 exercises per session. She increased the resistance in 3 of 5 strength (force-generating capacity) training exercises and achieved the highest degree of difficulty in all functional exercises. During the TEP and follow-up, the patient reported improvements in pain, joint stiffness, and physical function. Performance improved on the following physical tests: isokinetic peak torque strength (60 degrees /s) in hip extension (40%), hip flexion (27%), knee extension (17%), and knee flexion (42%); hip ROM extension (8 degrees ); and 6-minute walk distance (83 m). DISCUSSION The patient experienced less pain and improved physical function and physical test outcomes after intervention and at the 6-month follow-up. The main challenges when prescribing an exercise program for a patient with hip OA are monitoring the exercises to provide improvements without provoking persistent pain and motivating the patient to achieve long-term adherence to exercising. Randomized clinical trials are needed to evaluate the efficacy of this TEP in patients with hip OA.

Abstract
BACKGROUND Intra-articular injections of sodium hyaluronate (Na-HA) and corticosteroid (CS) are often used for the treatment of osteoarthritis (OA), and the clinical usefulness of such treatment has been reported. Some studies have discussed the effectiveness of intra-articular drug injection therapy in terms of the clinical results, but no cohort studies have performed evaluations of effectiveness based on changes in joint biomarkers. This prospective randomized study compared the efficacy of Na-HA and CS injections based on clinical scores and levels of biochemical markers for osteoarthritis. METHODS A total of 51 patients with knee osteoarthritis received intra-articular injections of either Na-HA or CS and were followed for 6 months after treatment. Pain and inflammatory scores were evaluated at the baseline, at 5 weeks, and at 6 months. We also measured joint fluid levels of hyaluronan (HA), chondroitin 6-sulfate, chondroitin 4-sulfate, matrix metalloproteinase (MMP)-9, and tissue inhibitor of MMP (TIMP)-1 at the baseline and at 5 weeks. RESULTS In both groups, injection therapy significantly improved pain/inflammation scores and visual analog scale scores with time (P < 0.01). HA levels were significantly increased after injection only in the Na-HA group (P < 0.05); and the MMP-9 level decreased significantly after injection only in the Na-HA group (P < 0.01). Other marker levels did not differ significantly between groups. CONCLUSIONS The results of this prospective randomized study suggest that the clinical effects of Na-HA and CS as local therapies for OA are comparable and that both drugs are useful. Considering the results of the measurement of biomarkers, compared with CS injection therapy Na-HA injection therapy may have protective effects on the articular cartilage by increasing the HA concentration in synovial fluid, as well as inhibitory effects on the catabolism of articular cartilage by reducing the MMP-9 concentration.

Abstract
OBJECTIVE The control of angiogenesis during chondrogenic differentiation is an important issue affecting the use of stem cells in cartilage repair, especially with regard to the persistence of regenerated cartilage. This study was undertaken to investigate the effect of vascular endothelial growth factor (VEGF) stimulation and the blocking of VEGF with its antagonist, soluble Flt-1 (sFlt-1), on the chondrogenesis of skeletal muscle-derived stem cells (MDSCs) in a rat model of osteoarthritis (OA). METHODS We investigated the effect of VEGF on cartilage repair in an immunodeficiency rat model of OA after intraarticular injection of murine MDSCs expressing bone morphogenetic protein 4 (BMP-4) in combination with MDSCs expressing VEGF or sFlt-1. RESULTS In vivo, a combination of sFlt-1- and BMP-4-transduced MDSCs demonstrated better repair without osteophyte formation macroscopically and histologically following OA induction, when compared with the other groups. Higher differentiation/proliferation and lower levels of chondrocyte apoptosis were also observed in sFlt-1- and BMP-4-transduced MDSCs compared with a combination of VEGF- and BMP-4-transduced MDSCs or with BMP-4-transduced MDSCs alone. In vitro experiments with mixed pellet coculture of MDSCs and OA chondrocytes revealed that BMP-4-transduced MDSCs produced the largest pellets, which had the highest gene expression of not only type II collagen and SOX9 but also type X collagen, suggesting formation of hypertrophic chondrocytes. CONCLUSION Our results demonstrate that MDSC-based therapy involving sFlt-1 and BMP-4 repairs articular cartilage in OA mainly by having a beneficial effect on chondrogenesis by the donor and host cells as well as by preventing angiogenesis, which eventually prevents cartilage resorption, resulting in persistent cartilage regeneration and repair.

Abstract
BACKGROUND Increased muscle co-activation during gait has been identified as a neuromuscular alteration associated with knee osteoarthritis, however levels of co-activation among different osteoarthritis severity have not been established. The purpose of this study was to determine if differences in co-activation could be detected among asymptomatic controls, those with moderate and those with severe osteoarthritis using a co-activation index and a pattern recognition technique. METHODS Surface electromyograms from vastus lateralis and medialis, lateral and medial hamstring and gastrocnemius pairs were recorded from 63 asymptomatic, 59 moderate and 48 severe osteoarthritic subjects during self-selected walking. A co-activation index was calculated over the initial stance for four medial and lateral muscle pairs. The four co-activation indices were tested among groups using a one factor ANOVA (alpha=0.05). Gait waveform pattern recognition procedures were applied to yield a principal pattern, scored for each muscle site and subject. A mixed model ANOVA (group-muscle) tested for principal pattern score differences. FINDINGS A significant group effect was found (P<0.05) for all four co-activation indices. Principal pattern one captured the amplitude and general shape of activity throughout the entire stance phase. ANOVA revealed a significant (P<0.05) group by muscle interaction for the principal pattern scores. Significant differences were found among all three groups and between the two osteoarthritic groups for both measures. INTERPRETATION The co-activation indices and principal patterns identified that lateral site differences occurred among all three groups with medial site differences between the two osteoarthritic groups. These findings suggest that measures of muscle co-activity provide additional information related to knee osteoarthritis severity.

Abstract
AIMS To compare tissue concentrations of diclofenac resulting from topical and oral applications of diclofenac according to clinically recommended prescriptions. METHODS Diclofenac sodium was applied to 14 subjects (four male and 10 female), who were scheduled to undergo knee arthroplasty due to osteoarthritis, according to the oral or topical prescription (a capsule containing 37.5 mg diclofenac sodium or two tapes containing a total of 30 mg diclofenac sodium). At 12 h after prescription, the diclofenac concentration in the fat, muscle and synovial tissues was measured with liquid chromatography and mass analysis. RESULTS The diclofenac concentration in the muscle was significantly higher (P = 0.0196) after topical application (average 9.29 ng ml(-1)) than after oral application (0.66 ng ml(-1)), whereas there was no significant difference in the plasma diclofenac level (4.70 and 6.63 ng ml(-1)) between the two applications. The concentration in the synovial membrane was significantly (P = 0.0181) lower in the topical application (4.99 ng ml(-1)) than in the oral application (15.07 ng ml(-1)). CONCLUSIONS Whereas plasma levels resulting from topical and oral applications of diclofenac according to clinically recommended prescriptions were comparable, concentration levels in the muscle and synovial tissues were different.

Abstract
OBJECTIVE To evaluate the effects of Tai Chi Qigong training on the quality of life and physical function of patients with osteoarthritis of the knee. DESIGN A preliminary, single-blind, randomized controlled trial. SETTING General community, performed at Hwaseong City Health Center. PARTICIPANTS Forty-four elderly subjects (mean age, 69.1 +/- 5.4 years) with knee osteoarthritis. INTERVENTION The patients were randomized (2:1) to: (1) an eight-week Tai Chi Qigong training programme or (2) a waiting list control group. The programme involved eight weeks of group Tai Chi Qigong sessions, with 60 minutes per session twice a week. MAIN OUTCOME MEASURES The primary outcome was quality of life measured with the Short Form 36 (SF-36) at baseline and week 8. Secondary outcomes included the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and 6-m walking time. RESULTS The training group had statistically significant improvements in the quality of life (changes of SF-36, Qigong versus control: 21.6 +/- 16.8 versus 9.8 +/- 13.6, P < 0.05) and 6-m walking test (change in walking time, Qigong versus control: -1.6 +/- 1.7 versus -0.2 +/- 0.8 s, P < 0.01). The WOMAC scores in the training group were markedly improved, although the differences were not statistically significant. CONCLUSIONS Tai Chi Qigong training appears to have beneficial effects in terms of the quality of life and physical functioning of elderly subjects with knee osteoarthritis. However, more rigorous trials are needed to confirm the efficacy of this training for patients with osteoarthritis of the knee.

Abstract
The purpose of the study was to examine the clinical efficacy of individually prescribed laterally wedged orthoses and walking shoes in the treatment of medial knee osteoarthritis using a prospective, single-blind, block-randomized controlled design. Sixty-six subjects (29 males, 37 females, mean age 62.4 years, mean BMI 33.0 kg/m(2)) were block-randomized to a lateral wedge (treatment) or neutral (control) orthotic group. Both groups were issued a standardized walking shoe for use with the orthoses. Primary outcome measures included the pain, stiffness, and functional limitations subscales of the Western Ontario and McMaster Universities index. Secondary outcome measures included the 6-minute walk distance and pain change, and stair negotiation time and pain change. A significant interaction (p=0.039) favoring the treatment group was observed for pain change during the 6-minute walk. The treatment group demonstrated significant improvements at both 1 month (p<0.001) and 1 year (p<0.001) compared to baseline. The control group only demonstrated significant improvements at 1 year (p=0.017). No other interactions were observed. Both groups were improved at each follow-up in the WOMAC subscales for pain (p<0.001), stiffness (p<0.001), and physical function (p<0.001). Both groups also improved in 6-minute walk test distance (p<0.001), stair negotiation test time (p=0.004), and stair negotiation test pain change (p<0.001). The results suggest that both neutral and laterally wedged orthoses may be beneficial in the management of medial knee osteoarthritis when used with walking shoes. However, the addition of lateral wedging was associated with early improvements in 6-minute walk test pain change not seen in the control group.

Abstract
OBJECTIVE To test the hypothesis that an association exists between the characteristics of the knee adduction moment and foot progression angle (FPA) in asymptomatic individuals and those with mild to moderate and severe knee osteoarthritis (OA). DESIGN Fifty asymptomatic individuals, 46 patients with mild to moderate and 44 patients with severe knee OA were recruited. Maximum knee adduction moment during late stance and principal component analysis (PCA) were used to describe the knee adduction moment captured during gait. Multiple regression models were used for each of the three group assignments to analyze the association between the independent variables and the knee adduction moment. RESULTS FPA explained a significant amount of the variability associated with the shape of the knee adduction moment waveform for the asymptomatic and mild to moderate groups (P<0.05), but not for the severe group (P>0.05). Walking velocity alone explained significant variance associated with the shape of the knee adduction moment in the severe OA group (P<0.05). CONCLUSION A toe out FPA was associated with altered knee adduction moment waveform characteristics, extracted using PCA, in asymptomatic individuals and those with mild to moderate knee OA only. These findings are directly implicated in medial knee compartment loading. This relationship was not evident in those with severe knee OA.

Abstract
Osteoarthritis and articular fractures are commonly responsible for early retirement from athletic performance. The subchondral bone (SCB) in those conditions is being recognized as an integral component in their pathophysiology. Early recognition of these potentially career-ending diseases may require understanding of the progression of changes occurring in SCB with time and exercise.

Abstract
STUDY DESIGN A randomized clinical trial design. OBJECTIVE To investigate the efficacy of high, repetitive, target-matching foot-stepping exercise (TMFSE) performed in a sitting position on proprioception, functional score, and walking velocity for patients with knee osteoarthritis (OA). BACKGROUND Researchers have suggested that exercises to address knee OA should include proprioceptive training. However, most patients cannot tolerate conventional proprioceptive training performed in a standing position. METHODS AND MEASURES Forty-nine subjects (mean age +/- SD, 63.3 +/- 8.1) with knee OA were randomly assigned to the exercise or no intervention groups. The exercise group practiced TMFSE in sitting, 3 sessions weekly for 6 weeks. All subjects underwent assessments of knee reposition error, functional incapacity score, and walking velocity prior to and after intervention. RESULTS The TMFSE significantly improved reposition error from a mean +/- SD of 3.0 degrees +/- 1.6 degrees to 1.5 degrees +/- 0.6 degree, walking velocity on ground level from 44.1 +/- 2.9 to 38.6 +/- 2.5 sec for 60 meters, time to complete a stairs task from 34.2 +/- 2.1 to 26.5 +/- 2.3 seconds, time to complete a figure-of-eight from 51.3 +/- 6.7 to 29.1 +/- 3.6 seconds, and score on a functional incapacity scale from 12.0 +/- 3.1 to 4.9 +/- 1.7, in subjects with knee OA after 6-week intervention (P <.0125). In contrast, the control group showed no change in any of the measured tests. CONCLUSION TMFSE in sitting appears to be an option for exercise in patients with mild to moderate knee OA. This may be an especially attractive option for patients who may have pain with weight-bearing exercises. A longitudinal study with a larger sample size is needed to confirm the potential use of TMFSE for patients with knee OA.

Abstract
We examined if a subject-specific amount of lateral wedge added to a foot orthosis could alter knee mechanics to potentially reduce the progression of knee osteoarthritis in patients with medial knee osteoarthritis. Twenty individuals with medial knee osteoarthritis (>/=2 Kellgren Lawrence grade) were prescribed a custom laterally wedged foot orthotic device. The prescribed wedge amount was the minimal wedge amount that provided the maximum amount of pain reduction during a lateral step-down test. Following an accommodation period, all subjects returned to the laboratory for a gait analysis. Knee mechanics were collected as the subjects walked at an intentional walking speed. Walking in the laterally wedged orthotic device significantly reduced the peak adduction moment during early stance (p < 0.01) compared to the nonwedged device. Similarly, the wedged orthotic device significantly reduced the knee adduction excursion from heel strike to peak adduction (p < 0.01) compared to the nonwedged device. No differences in the peak adduction moment during propulsion or peak adduction during stance were observed between the orthotic conditions. A subject-specific laterally wedged orthotic device was able to reduce the peak knee adduction moment during early stance, which is thought to be associated with the progression of knee osteoarthritis. Previous studies on this device have reported issues associated with foot discomfort when using wedge amounts >7 degrees; however, no such issues were reported in this study. Therefore, providing a custom laterally wedged orthotic device may potentially increase compliance while still potentially reducing disease progression.

Abstract
Patients with knee osteoarthritis (OA) find that use of elastic knee sleeves gives them partial pain relief and a greater sense of joint stability. However, the scientific effects of knee OA patients wearing braces are unclear. The purpose of this study was to investigate the effects of knee sleeves on static and dynamic balance in knee OA patients. Fifty patients with knee OA were enrolled in the study and all subjects were randomly divided into two groups. Initially, subjects in group A did not wear a neoprene sleeve while receiving balance tests but then wore them to be re-tested. Subjects in group B did just the reverse procedure. In this investigation, an instrument (KAT 2000; Breg Inc., Vista, CA, USA), which quantified motor control performance of the lower extremities was used and balance scores from the KAT 2000 software were obtained. The results revealed that the scores of patients wearing braces were significantly lower than those of patients without braces (p < 0.05).The finding of this study demonstrated that knee OA patients wearing knee sleeves could experience increased balance ability in both static and dynamic conditions. The improvement might prevent knee OA patients from falling down and increase their sense of security during physical activities.

Abstract
OBJECTIVE To evaluate the effects of tai chi consisting of group and home-based sessions in elderly subjects with knee osteoarthritis. DESIGN A randomized, controlled, single-blinded 12-week trial with stratification by age and sex, and six weeks of follow-up. SETTING General community. PARTICIPANTS Forty-one adults (70 +/- 9.2 years) with knee osteoarthritis. INTERVENTIONS The tai chi programme featured six weeks of group tai chi sessions, 40 min/session, three times a week, followed by another six weeks (weeks 7 -12) of home-based tai chi training. Subjects were requested to discontinue tai chi training during a six-week follow-up detraining period (weeks 13-18). Subjects in the attention control group attended six weeks of health lectures following the same schedule as the group-based tai chi intervention (weeks 0 -6), followed by 12 weeks of no activity (weeks 7-18). MAIN OUTCOME MEASURES Knee pain measured by visual analogue scale, knee range of motion and physical function measured by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were recorded at baseline and every three weeks throughout the 18-week study period. Data were analysed using a mixed model ANOVA. RESULTS The six weeks of group tai chi followed by another six weeks of home tai chi training showed significant improvements in mean overall knee pain (P = 0.0078), maximum knee pain (P = 0.0035) and the WOMAC subscales of physical function (P = 0.0075) and stiffness (P = 0.0206) compared to the baseline. No significant change of any outcome measure was noted in the attention control group throughout the study. The tai chi group reported lower overall pain and better WOMAC physical function than the attention control group at weeks 9 and 12. All improvements disappeared after detraining.

Abstract
ABSTRACTWhile the physical correlates of knee osteoarthritis are well documented, less well documented are aspects of psychological functioning that may affect overall health and functional status. This paper describes the findings of a cross-sectional analysis that examined the strength of the relationship between selected psychological factors and the walking ability of adults with knee joint osteoarthritis. The variables assessed were pain, depression, levels of self-efficacy for pain and other-symptoms management, walking endurance, walking speed, and perceived exertion when walking. The sample, including 57 persons with unilateral and 43 persons with bilateral radiographic and symptomatic knee osteoarthritis, mean age, 69.9 ± 1 years, underwent standard assessment procedures on a single test occasion using several validated questionnaires and a series of walking tests on level ground. Bivariate and multiple regression analyses revealed that (a) higher pain and other-symptoms self-efficacy scores were associated with lower levels of pain (r= −0.29, −0.20.), perceived exertion during a walking task (r= −0.29, −0.31), and depression scores (r= −0.46, −0.54) (p< 0.001); (b) subjects with higher levels of self-efficacy for managing symptoms other than pain also recorded faster and fast speed walking velocities than those with lower self-efficacy scores (r= 0.30, 0.31) (p< 0.001); (c) self-efficacy for pain was the strongest predictor of pain intensity, and self-efficacy for symptom management was the strongest predictor of perceived exertion during walking, depression, and pain self-efficacy. Although no cause–effect relationship can be deduced from a cross-sectional analysis, these data imply that efforts to heighten self-efficacy for pain and other-symptoms management may influence the affective status, function, and effort-related perceptions of people with knee osteoarthritis quite significantly.

Abstract
OBJECTIVES Knee osteoarthritis (OA) is a common chronic degenerative disorder. There are various treatment modalities. This study was planned to investigate the efficacy of balneotherapy, mud-pack therapy in patients with knee OA. METHODS A total of 80 patients with knee OA were included. Their ages ranged between 39-78. The patients were separated in to three groups. Group I (n=25) received balneotherapy, group II (n=29) received mud-pack therapy and group III (n=26) was hot-pack therapy group. The therapies were applied for 20 min duration, once a day, five times per week and a total of 10 session. Patients were assessed according to pain, functional capacity and quality of life parameters. Pain was assessed by using Visual Analogue Scale (VAS) and Western Ontario McMaster Osteoarthritis Index (WOMAC) pain scale (0-4 likert scale). Functional capacity was assessed by using WOMAC functional capacity and WOMAC global index. Quality of life was evaluated by Nottingham Health Profile (NHP) self-administered questionnaire. Also physician's global assessment and the maximum distance that patient can walk without pain, were evaluated. The assessment parameters were evaluated before and after three months. RESULTS There were statistically significant improvement in VAS and WOMAC pain scores in group I (p<0.001), group II and III (p<0.05). The WOMAC functional and global index also decreased in group I (p<0.05), group II (p<0.001) and hot-pack group (p<0.05). Quality of life results were significantly improved in balneotherapy and mud-pack therapy groups (p<0.05). No difference was observed in hot-pack therapy group (p>0.05). The maximum distance was improved both in group I and II (p<0.05) but not in group III. Also physician's global assessment was found to be improved in all groups (p<0.05). CONCLUSIONS Balneotherapy and mud-pack therapy were effective in treating patients with knee OA.

Abstract
Intra-articular drug delivery is the preferred standard for targeting pharmacologic treatment directly to joints to reduce undesirable side effects associated with systemic drug delivery. In this study, a biologically based drug delivery vehicle was designed for intra-articular drug delivery using elastin-like polypeptides (ELPs), a biopolymer composed of repeating pentapeptides that undergo a phase transition to form aggregates above their transition temperature. The ELP drug delivery vehicle was designed to aggregate upon intra-articular injection at 37 degrees C, and form a drug 'depot' that could slowly disaggregate and be cleared from the joint space over time. We evaluated the in vivo biodistribution and joint half-life of radiolabeled ELPs, with and without the ability to aggregate, at physiological temperatures encountered after intra-articular injection in a rat knee. Biodistribution studies revealed that the aggregating ELP had a 25-fold longer half-life in the injected joint than a similar molecular weight protein that remained soluble and did not aggregate. These results suggest that the intra-articular joint delivery of ELP-based fusion proteins may be a viable strategy for the prolonged release of disease-modifying protein drugs for osteoarthritis and other arthritides.

Abstract
OBJECTIVES To compare the effects of two hyaluronic acid (HA) formulations on mediators of matrix turnover and inflammation in an IL-1-treated cartilage-synovium co-culture model with the aim of elucidating mechanisms by which viscosupplementation exerts beneficial effects in osteoarthritic joints. DESIGN A co-culture model (100 ng/ml interleukin-1beta (IL-1beta) added to canine synovial and cartilage explants) was used to investigate the effects of HA on cartilage-synovium interactions. Three concentrations (1x, 0.5x, and 0.1x) of two commercial sources of HA (A: Synvisc [hylan G-F 20]; B: Hyalgan [sodium hyaluronate]) were used. Co-cultures without IL-1beta (negative) or with IL-1beta (positive) but neither HA product served as controls. The liquid media were collected every 3 days and explants of cartilage and synovium were collected on days 3, 6, and 20. Media and explants were analyzed histologically, biochemically, and immunohistochemically. RESULTS Glycosaminoglycan (GAG) content was measured in cartilage explants. GAG content in explants was higher in both HA groups at the beginning and the conclusion of the study compared to the IL-1beta-treated group. GAG content of the media was significantly (P<0.05) lower in the Synvisc group than all other groups early. The Hyalgan group demonstrated progressively less GAG release later in the study. The addition of Synvisc did not decrease the matrix metalloproteinase (MMP)-3 concentrations at any point. MMP-3 concentrations were significantly (P<0.05) lower among the 1x and 0.5x Hyalgan groups on day 20 compared to the IL-1beta-treated group. On day 3, prostaglandin E(2) concentrations were significantly (P<0.05) higher in the IL-1beta-treated group compared to other groups. Both HA groups had less nitric oxide production than the control groups throughout the study. CONCLUSIONS This study supports two potential mechanisms for viscosupplementation: a biosynthetic-chondroprotective mechanism, with a possible delay in onset depending on the form of HA; and an anti-inflammatory mechanism.

Abstract
OBJECTIVE To investigate the effects of intraarticular hyaluronic acid (HA) (Artzal, Seikagaku Corp., Japan) in geriatric participants with unilateral knee osteoarthritis (OA). METHOD This was a prospective, observer-blind study with 6 months follow-up done in the setting of an outpatient rehabilitation department in a university-affiliated tertiary care medical center. Sixty-eight patients, aged 65 years or above, with symptoms and radiographic evidence of unilateral knee OA for at least 6 months were recruited. Patients received five weekly intraarticular injections of Artzal into symptomatic knees. Fifty-six participants completed the study. Fifty age-, body mass- and gender-matched healthy individuals were selected as control. Visual analog scale (VAS), Lequesne index and four balance tests including single-leg stance test (SLS), function reach test (FRT), timed "Up-and-Go" test (TUG) and Berg balance scale (BBS) were assessed before injection and at each follow-up visit in the OA group. Four balance tests were obtained on healthy participants for data comparison. RESULTS Before Artzal injections, the OA group showed significantly worse VAS, Lequesne index and four balance tests scores than did the control group (P < 0.001). Significant improvement in all outcome measures were noted at 1 week, 1, 3 and 6 months post the fifth injection compared with baseline before injection. Local adverse events were reported in four patients (7.1%). CONCLUSION Significant improvement in pain, physical function and balance tests was demonstrated after five weekly Artzal injections in geriatric patients with knee OA. The effect had rapid onset at 1 week and may last for 6 months.

Abstract
Two analyses were performed to assess the effectiveness of off-loading knee braces in producing condylar separation of degenerative compartments in patients with unicompartmental knee osteoarthritis. All patients were analyzed using video fluoroscopy under weight-bearing conditions. In the initial study, a single brace was analyzed in 2 dimensions and demonstrated that medial condylar separation was obtained, with corresponding pain relief, in 78% of patients. The brace was least effective in obese patients. The second study consisted of a 3-dimensional analysis of 5 subjects fitted with 5 different off-loading braces. Condylar separation in most patients was similarly observed with certain braces, whereas others demonstrated little to no condylar separation, suggesting that off-loading knee braces are not equally effective in treatment of unicompartmental knee arthritis.

Abstract
OBJECTIVE To study osteoarthritis in the equine medial femorotibial (MFT) joint after a single traumatic injury. ANIMALS 10 mature horses. PROCEDURE In vitro explant cultures were used to determine injury threshold for stifle joint cartilage. Contusive impacts were applied to the medial femoral condyle (MFC), and horses were followed for 84 (n = 5) and 180 days (5). Synovial fluid samples were collected every 14 days for determination of sulphated glycosaminoglycan (sGAG) concentrations. Radiographic and lameness evaluations were performed. Gross and histologic descriptions, and immunohistochemistry, cartilage sGAG content determination, and cartilage aggregate modulus determination were performed at the MFC impact site (MFCi), MFC nonimpact site (MFCn), and medial tibial plateau (MTP). RESULTS Synovial fluid sGAG concentration decreased significantly on days 14, 28, 42, and 56 in all horses. Macroscopic and microscopic articular lesions developed within all MFT joints. No radiographic abnormalities were observed. Mild lameness was evident in several horses. No significant differences were found between short-term and longterm cohorts of horses with respect to histologic scores and TUNEL results. On immunohistochemistry, MFCi was positive for COL2-(3/4)C(short). International Cartilage Repair Society scores differed significantly between short-term and long-term cohorts of horses. In all horses, sGAG concentrations were significantly decreased at the MFCi, compared with the MFCn. CONCLUSIONS AND CLINICAL RELEVANCE Use of contusive impacts on the MFC of horses results in cartilage lesions that are similar to those described clinically, supporting trauma as a contributing factor in the natural pathogenesis of osteoarthritis.
