Editorial Commentary: Hip Arthroscopy in Patients With Moderate to Advanced Osteoarthritis Shows Unpredictable Results.

Abstract

Hip arthroscopy is an effective surgical approach for the treatment of femoroacetabular impingement (FAI) syndrome with concomitant mild hip osteoarthritis (OA). However, in the FAI patients with moderate to advanced hip OA (Tönnis grade 2 or greater), whether hip arthroscopy could provide symptomatic relief or delay the need for an ultimate total hip arthroplasty surgery is controversial. The literature is heterogeneous and of generally lower quality evidence. Recent research reporting 10-year outcomes of hip arthroscopy in patients with hip OA shows 57% survivorship, and 78% survivor satisfaction. With unpredictable results, surgeons and well informed patients could hold some hope for a positive outcome after arthroscopy of an arthritic hip. As the Tönnis grading system shows poor interobserver reliability, surgeons may need to carefully consider their personal indications and resultant outcomes.
