Muscle weakness as difference between patients with knee osteoarthritis compared to individuals without knee complaints. Strength directions for joints with largest weaknesses on top and the smallest on the bottom. Notes: Effect size = Standardized mean difference or Cohen’s d, KOA = knee osteoarthritis, Inv. = (most) involved leg, I = (most) involved leg, EV = eversion, ER = external rotation, FLX = flexion, EXT = extension, PF = plantar flexion, DF = dorsal flexion, INV = inversion, AD = adduction, Uninv. = (least or) uninvolved leg, U = (least or) uninvolved leg, AB = abduction
