Outcomes of Hip Arthroscopic Surgery in Patients With Tönnis Grade 1 Osteoarthritis With a Minimum 2-Year Follow-up: Evaluation Using a Matched-Pair Analysis With a Control Group With Tönnis Grade 0.

Abstract:There are limited studies on the effect of mild osteoarthritis (OA) on outcomes of hip arthroscopic surgery.

METHODS: Data were prospectively collected on patients who underwent hip arthroscopic surgery between April 2008 and December 2012. Patients were excluded if they had previous hip conditions. The remaining patients were divided into either Tönnis 0 or 1 grade OA groups and were matched in a 1-to-1 ratio according to age within 5 years, sex, body mass index category, labral treatment, and capsular treatment. Four patient-reported outcome (PRO) scores, as well as the visual analog scale (VAS) score for pain, patient satisfaction, and rates of revision arthroscopic surgery and conversion to total hip arthroplasty (THA), were recorded.
