Hip Arthroscopy in the Presence of Advanced Osteoarthritis Results in 57 Survivorship, With 78 Survivor Satisfaction, at 10 Years. A Matched-Control Study

? 2022 Arthroscopy Association of North AmericaPurpose: To (1) determine the 10-year survivorship (avoidance of total hip arthroplasty, THA) for patients with advanced osteoarthritis (OA) undergoing hip arthroscopy for femoroacetabular impingement, and (2) compare survivorship and patient-reported outcomes (PROs) with a matched-control group without OA. Methods: Advanced OA hips (T?nnis ≥2) were matched in a 1:1 ratio (age ± 5 years, sex) to hips with preoperative T?nnis grade ≤1. Exclusion criteria was dysplasia, age 35 years respectively) (P = .002). Conversion to THA was greater for increasing T?nnis: HR 1.9 (P = .450), 3.5 (P = .032), and 11.0 (P 35 years: HR 4.3 (95% confidence interval 1.6-11.3, P = .003). Patient acceptable symptomatic state achievement was similar for both groups (78% OA vs 91% control, P = .167). modified Harris Hip Score and Short Form-36 significantly improved within both groups from baseline to 10 years Conclusions: Arthroscopic correction of femoroacetabular impingement, in the presence of advanced OA results in 57% survivorship at 10 years (68% T?nnis 2, 25% T?nnis 3). Where THA was avoided, 78% considered their 10-year post-HA state to be satisfactory, with patient-reported outcomes similar to a matched non-OA cohort. T?nnis 2 in particular should be considered for arthroscopic hip preservation to avoid the need to prematurely replace the hip joint. Level of Evidence: IV, case series.
