Does DHA/EPA supplementation benefit those with osteoarthritis?

There has been a large number of clinical trials indicating moderate benefit of supplementing with DHA/EPA (2000-3000 mg /day for 14 -16 weeks)in those with rheumatoid arthritis. Very few studies have been conducted in individuals with osteoarthritis. One carefully-controlled clinical trial as published in 1992 on 86 patients reported no significant benefit for the patients taking cod liver oil as compared to the control group taking a placebo.
