Background: Use of proprioceptive knee braces to control symptomology by altering neuromuscular control mechanisms has been shown in patellofemoral pain. Although their potential in patients with knee osteoarthritis is vast, little research has examined their efficacy. Objectives: This study examines the effect of a proprioceptive knee brace on lower limb kinematics and kinetics in healthy participants and in participants with OA. Methods: Thirteen healthy participants were asked to perform a 10-cm step-down task with and without a proprioceptive brace. Data were collected using a 10-camera Qualisys system. Individuals with osteoarthritis completed the Knee injury and Osteoarthritis Outcome Score before and after 4 weeks of intervention. Results: During step-down reductions in knee maximum internal rotation, transverse range of movement, transverse plane angular velocity and maximum internal rotation angular velocity was seen. Ankle plantar flexion and inversion angular velocity decreased while inversion and maximum supination angular velocity increased. Improvements in Knee injury and Osteoarthritis Outcome Score were noted across all parameters with brace use. Conclusion: Positive changes in kinematic variables in multiple planes can be achieved with proprioceptive bracing alongside improved patient outcome. These changes occur at the knee but analysis of other weight bearing joints should not be overlooked in future studies. This study supports the concept of neuromuscular reinforcement and re-education through proprioceptive bracing and its application in the management in knee osteoarthritis. Clinical relevance Proprioception can alter symptoms and biomechanics embraced and adjacent lower limb joints. The results of this study highlights the potential uses of non-mechanical bracing in the treatment of osteoarthritis and other potential to bridge the osteoarthritis treatment gap. Furthermore, large-scale research is needed to match disease subset to brace type.

BACKGROUND: Knee osteoarthritis (OA) impairs postural control and may be affected by how the lower limb joints are used. OBJECTIVE: To investigate how individuals with knee OA use lower limb joints for static postural control. METHODS: Ten patients with knee OA and thirteen healthy controls performed quiet standing for 30 s. The standard deviation of the center of mass (COM) and lower limb joint motions in the anterior-posterior (AP) and medial-lateral (ML) planes were calculated from three-dimensional marker trajectories. Pearson’s correlation analysis and independent t-tests were conducted to investigate the relationship between COM and lower limb joint motion and to compare group difference, respectively. RESULTS: The AP hip angular velocity alone in the knee OA group and the AP hip and knee angular velocity in the control group were significantly correlated with the AP COM velocity. The ML hip angular velocity was significantly correlated with the ML COM velocity in both groups. The knee OA group exhibited a significantly larger standard deviation of AP COM velocity than the control group. CONCLUSIONS: Individuals with knee OA depended solely on the contribution of the hip to the AP COM velocity, which could not be successfully controlled by the knee.

Objective.To examine the influence of different analytical methods, baseline covariates, followup periods, and anchor questions when establishing a minimal important difference (MID) for individuals with knee osteoarthritis (OA). Second, to propose MID for improving and worsening on the Knee injury and Osteoarthritis Outcome Score (KOOS).Methods.Retrospective analysis of prospectively collected data from 272 patients with knee OA undergoing a multidisciplinary nonsurgical management strategy. The magnitude and rate of change as well as the influence of baseline covariates were examined for 5 KOOS subscales over 52 weeks. The MID for improving and worsening were investigated using 4 anchor-based methods.Results.Waitlisted for joint replacement and exhibiting unilateral/bilateral symptoms influenced change in KOOS over time. Generally, low correlations between anchors and KOOS change scores limited calculations of MID; thus, they were only proposed for the pain, activities of daily living, and quality of life subscales. The method used to calculate the MID influenced the cutpoint; however, the type of anchor question only influenced the MID when analyzed with a particular mean change method. Depending on patient and clinical characteristics, the subscale, and the analytical approach used, the MID for KOOS improvement ranged from an absolute change of −1.5 to 20.6 points and worsening ranged from −19.17 to 8.5 points.Conclusion.MID vary with patient and clinical characteristics, KOOS subscale, and analytical approach. Provided the anchor question is relevant to the patient-reported outcome and baseline status is considered, the anchor does not appear to influence the MID for improvement or worsening when using some anchor-based methods.

Background:Overweight is a major risk factor for the development and progression of knee osteoarthritis (OA). Weight loss for patients with knee OA has been associated with improvement in self-reported pain and function and is recommended by EULAR as part of the therapeutic management.Objectives:The aim of the study was to evaluate the relation between overweight and functional impairment in adults with knee OA.Methods:It was a prospective study conducted in a rheumatologic department over a 4 months period. Patients with symptomatic knee OA based on the ACR criteria, were included. A screening of body mass index (BMI) was carried out for all patients. It was categorized following the WHO classification into: normal (<25 kg/m2), overweight (25 to <30), obese (up to 30).Pain level was evaluated using the Visual Analogue Scale (VAS). Function was assessed by the short form of the Knee injury and Osteoarthritis Outcome Score (KOOS-PS) (KOOS-PS scores to 0 representing no difficulty and 100 representing extreme difficulty). The patients’ knee radiographies were graded according to Kellgren Lawrence criteria (KL). The patients were allocated in two groups; as grade I-II KL (Group 1) and grade III-IV KL (Group 2).Results:We included 143 patients with a mean age of 65.17± 10.7 years and 88.1% of women. Patients were from low socio-economic class in 30.8% of cases. Mean disease duration of the KOA was 5.4 years [3months-20 years] and mean BMI was 31.8±5.6kg/m2. Patients were with normal weight in 16.1%, overweight in 19.6% and obese in 64.3%.Knee OA was bilateral in 85.3% and other OA sites were associated in 37.8% of patients. Mean VAS pain of knee OA was 6.6±1.5 and KOOS-PS was 48.8±16.5/100. Concerning the radiographic damage; we found grade I-II (KL) in 22.6% and grade III-IV (KL) in 77.4%.High BMI (BMI≥25 kg/m2was not significantly associated with worse KOOS score (p=0.9), more pain (p=0.5) or an increasing severity of radiological knee osteoarthritis (p=0.14). Moreover, the level BMI was not associated with the presence of other OA sites (p=0.9) or a bilateral KOA (p=0.07).Conclusion:These data, from a subset of participants with symptomatic radiographic knee OA, demonstrate no correlation between obesity and pain, functional impairment and radiographic severity.Acknowledgments:noneDisclosure of Interests:None declared

Background and Objective: Knee osteoarthritis is one of the most common rheumatologic problems. To investigate risk factors related to the knee osteoarthritis a case-control study was performed using cases diagnosed in the Community Oriented Program for Control of Rheumatic Diseases (COPCORD) study, stage I. Methods: Using data from the 2012 COPCORD study, stage-I that was conducted in Sanandaj, northwestern of Iran, we runned a case-control study in 2014-2015. Cases were 700 knee osteoarthritis using American College of Rheumatology (ACR) criteria, frequency matched with 700 healthy controls that were randomly selected from the general population. Results: In multivariate analysis, statistical significant relation was observed between knee OA and some studied factors such as body mass index (P <0.001), lodging (living in highland vs. plain) (P <0.001), type of used toilet (regular vs. toilet) (P <0.001), history of using high-heeled shoes (>3 cm) (P = 0.005), history of knee Injury (P = 0.04), history of lower limb fracture (P = 0.02), Number of pregnancies (P <0.001) and history of pain and swelling (lasting for one months) (P = 0.04). Conclusions: Living in highland area, using regular toilet, having knee injury and lower limb fracture in the past were most significant associated factors with occurrence of knee osteoarthritis. doi: https://doi.org/10.12669/pjms.35.3.277 How to cite this:Moghimi N, Rahmani K, Delpisheh A, Saidi A, Azadi NA, Afkhamzadeh A.

Background: Lateral wedge insoles adjusted by biomechanical analysis may improve the condition of patients with medial knee osteoarthritis. Design: This is a prospective, randomized, controlled, single-blind clinical trial. Setting: The study was conducted in a biomechanics laboratory. Subjects: A total of 38 patients with medial knee osteoarthritis were allocated to either an experimental group (lateral wedge insoles) or a control group (neutral insoles). Interventions: Experimental group ( n = 20) received an adjusted lateral wedge insole of 2, 4, 6, 8, or 10 degrees, after previous biomechanical analysis. Control group ( n = 18) received a neutral insole (0 degrees). All patients used the insoles for 12 weeks. Main measures: Visual analogue scale, Knee Injury and Osteoarthritis Outcome Score questionnaire, biomechanical parameters: first and second peak of the external knee adduction moment and knee adduction angular impulse, and physical performance tests: 30-second sit-to-stand test, the 40-m fast-paced walk test, and the 12-step stair-climb test. Results: After 12 weeks, between-group differences did not differ significantly for pain intensity (−12.5 mm, (95% CI −29.4–4.4)), biomechanical parameters ( p = 0.05), Knee Injury and Osteoarthritis Outcome Score, and physical performance tests, except on the Knee Injury and Osteoarthritis Outcome Score subscale other symptoms ( p = 0.002; 13.8 points, (95% CI 5.6–22.0)). Conclusion: Tailored wedge insoles were no more effective at improving biomechanical or clinically meaningful outcomes than neutral insoles, except on symptoms. More participants from the experimental group reported they felt some improvement. However, these effects were minimal and without clinical significance.
