How Much Arthritis Is Too Much for Hip Arthroscopy: A Systematic Review

Age-Related Trends in Hip Arthroscopy: A Large Cross-Sectional Analysis

“…28 A recent systematic review evaluating how much preoperative arthritis should preclude patients from hip arthroscopy suggests that patients with a Tonnis grade of 1 or greater or a joint space of 2 mm are more likely to require conversion to THA. 29 We believe the high rate of conversion in the older cohort is likely a result of the higher prevalence of OA. Over 99% of the patients who had conversions to THA had an associated diagnosis of OA, but limitations of the database prevent further clarification of whether OA was present at the initial arthroscopy or added on as a diagnosis at the time of THA.…”

Despite its current widespread use, evidence to support the indications for hip arthroscopy lags behind: a review of current literature

“…Two recent systematic reviews concerning arthroscopic treatment of osteoarthritic hips were reviewed 25 26…”

“…The first systematic analysis was by Domb et al 25 who reviewed the current literature in an attempt to determine the extent of preoperative OA that precludes the benefit from hip arthroscopy and refines the indications for hip arthroscopy in the setting of OA. The systematic review's inclusion criteria included papers that commented on preoperative factors, parameters, physical examination, or diagnostic testing that may be evidence of cartilage damage and/or arthritis, papers that contained outcome data on patients undergoing hip arthroscopy and papers that had a sample size of at least 10 patients with arthritic changes in the hip.…”

Avascular Necrosis, Osteoarthritis and Synovitis

“…According to a recent systematic review of Domb et al in 2015 [ 6 ], the risk of failure or the risk of osteoarthritis evolution is directly related to the importance of degenerative disorders with conversion to THA, ranging from 16 % to 52 % concerning Tönnis grade 2 or higher. Haviv and O'Donnell [ 17 ] described a rate of 16 % of THA conversion after 3 years, concerning 564 hip arthroscopies between 2002 and 2009 with cartilage disorders from 1 to 3 according to Tönnis rates.…”
