Association between quadriceps function and femoral cartilage characteristics in young adults with obesity

Adults with obesity are at greater risk for knee osteoarthritis (KOA). Greater quadriceps function, but not knee flexion during gait, was associated with a larger medial to lateral femoral cartilage thickness ratio and a lower femoral cartilage echo-intensity. Adverse femoral cartilage outcomes that are linked to quadriceps weakness may not be influenced by knee flexion during self-selected speed gait in adults with obesity.
