Where this comes from

Abstract

There are two main hypotheses for the cause of exercise related osteoarthritis: wear and tear of the articular cartilage and muscle dysfunction. This is a review of the clinical literature to see which hypothesis has the greatest support. Clinical studies support the muscle dysfunction hypothesis over the wear and tear hypothesis.
