Summary
Brief summary
The aim of this randomised controlled trial is to determine whether statins slow the progression of knee osteoarthritis. The hypothesis is that atorvastatin use will reduce the rate of knee cartilage volume loss over 2 years compared with placebo in people with symptomatic knee osteoarthritis.
