Gait differs between unilateral and bilateral knee osteoarthritis

Abstract

Objectives: To compare walking biomechanics in the most painful leg, and symmetry in biomechanics between legs, in individuals with (1) unilateral pain and structural osteoarthritis (OA), (2) unilateral pain, but bilateral structural OA, and (3) bilateral pain and structural OA and in (4) an asymptomatic control group. Design: Cohort study. Setting: Laboratory based. Participants: Participants with symptomatic and/or radiographic medial tibiofemoral OA in one or both knees (n=91), and asymptomatic control participants (n=31). Interventions: Not applicable. Main Outcome Measure: The peak knee adduction moment, peak knee flexion moment, knee varus-valgus angle, peak knee flexion angle, toe-out..
