EP5.5 Obese Patients Achieve Inferior Outcomes Compared to Non-Obese Patients Following Hip Arthroscopy: A Systematic Review

Abstract

Abstract Purpose The purpose of this study was to perform a systematic review to compare clinical outcomes and complication rates of obese versus non-obese patients following primary hip arthroscopy. Methods A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines by searching PubMed, Embase, and Cochrane Library to identify studies comparing outcomes of obese versus non-obese patients following hip arthroscopy. The search terms used were as follows: hip AND arthroscopy AND (obesity OR obese OR overweight). Outcomes included patient-reported outcomes (PROs), rates of revision hip arthroscopy and conversion to total hip arthroscopy (THA), and complications. Results Eleven studies (10 Level III, 1 Level IV) met inclusion criteria, including 461 obese and 1,821 non-obese patients. Mean age ranged from 38.0 to 48.4 years in the obese group and 32.1 to 42.2 years in the non-obese group. The percentage of males ranged from 27.4% to 47.6% and 27.4% to 39.2% in the obese and non-obese groups, respectively. Revision hip arthroscopy rates ranged from 0% to 8.1% in the obese group and 0% to 10.8% in the non-obese group. The conversion rate to THA ranged from 0% to 29.7% in the obese group and 0% to 14.9% in the non-obese group. Two studies reported significantly higher conversion rates to THA in the obese group. Six studies found a significantly higher modified Harris Hip Score (mHHS) in the non-obese group. Another study found a significantly higher mHHS in non-obese female patients when compared to obese females. Four studies found a significantly higher postoperative Non-Arthritic Hip Score (NAHS) in the non-obese group. Conclusion Obesity is associated with inferior postoperative patient-reported outcomes following hip arthroscopy, with select studies demonstrating higher rates of conversion to total hip arthroplasty and postoperative complications.
