Abstract

Background: Osteoarthritis adversely impacts hip arthroscopy outcomes. The purpose of this study was to conduct a matched-pair analysis with a mean follow-up of 2 years to evaluate the outcomes following hip arthroscopy in patients with Tönnis grade-2 osteoarthritis.

Methods: Data were prospectively collected on all patients undergoing hip arthroscopy during the study period from April 2008 to December 2012. Patients were excluded if they had previous hip conditions. Patients were categorized into Tönnis grade-0, grade-1, or grade-2 osteoarthritis groups and were matched in a 1:1 ratio according to age within 5 years, sex, and body mass index. Four patient-reported outcome scores, a visual analog scale (VAS) score for pain, patient satisfaction level, and rates of revision hip arthroscopy and conversion to total hip arthroplasty were recorded.
