High Knee Extensor Strength and Knee Osteoarthritis

Arthritis Care Res; ePub 2016 Mar 18; Thorlund, et al

Publish date:: March 28, 2016

High knee extensor muscle strength may protect against later development of knee osteoarthritis (OA) in some individuals with medial meniscal pathology, according to a study of 373 participants with medial meniscal pathology, but did not have radiographic knee OA, and 531 participants with symptomatic knee OA. Researchers found:

• High knee extensor strength was associated with reduced risk of radiographic knee OA in women (RR=0.52), but not in men (RR=0.56).

• High knee extensor strength did not protect against the development of symptomatic knee OA in either women or men.
