Hip arthroscopy in osteoarthritis: a systematic review of the literature.

BackgroundHip arthroscopy treatment in patients with osteoarthritis is controversial.Hypothesis/PurposeTo systematically review the clinical outcome of patients with hip osteoarthritis (OA) treated with arthroscopy and what proportion of these patients subsequently underwent total hip arthroplasty (THA).Study designSystematic review.MethodsPubMed, Cochrane library and LILACS were searched from January 1990 through December 2013 for eligible studies. The methodological quality of the collected data (applied to each study) was performed with a modified version of the Coleman methodology score (mCMS).Results11 studies were included in this review. Most of the studies included reported clinical improvements. The overall conversion rate to THA ranged from 9.5% to 50%. Mean time between arthroscopy and THA was 13.5 months.ConclusionsThe quality of studies is low. We have found inconclusive evidence to make categorical indications for hip arthroscopy in the treatment of OA, although we have found that there is s...
