Muscle quality is associated with pain in adults with symptomatic knee osteoarthritis, independent of muscle strength: Findings from the MyCA study.

These preliminary findings suggest that echo intensity and shear wave velocity may impact knee OA pain and could serve as malleable treatment targets. Findings also demonstrate that muscle quality is a unique construct, distinct from muscle strength, which may impact pain and treatment outcomes. More research is needed to fully understand the role of muscle quality in knee OA.
