Association of leg muscle symmetry with knee osteoarthritis

ConclusionsLeg muscle asymmetry in men, irrespective of obesity, was associated with significantly higher grade of radiographic knee OA and prevalent knee pain. Longitudinal studies will be needed to determine the cause-and-effect relationship and to determine whether the higher or lower mass, beyond the asymmetry, is associated with radiographic severity or symptomatic knee OA.Key Points•Leg muscle asymmetry was related to prevalence and radiographic severity of knee OA, especially in men.•Leg muscle asymmetry was associated with knee pain.•Those with both leg muscle asymmetry and obesity showed higher prevalence of knee pain and worse radiographic knee OA.
