Osteoarthrosis, advanced age and female sex are risk factors for inferior outcomes after hip arthroscopy and labral debridement for FAI Syndrome - Case Series with minimum 10-year follow-up.
Abstract
PURPOSE\nThe purpose of the study was (1) to determine the cumulative survivorship using the endpoint of THA correlated with osteoarthrosis (Toennis ≤1 versus Toennis >1) at minimum 10-year follow-up and to (2) identify risk factors for THA conversion.\n\n\nMETHODS\n112 Patients were examined who underwent hip arthroscopy for FAI syndrome (FAIS) between 2007 and 2009. The inclusion criterion was primary hip arthroscopy to treat FAIS with corresponding chondrolabral pathologies. The exclusion criteria were secondary hip pathologies, revision hip arthroscopy or dysplasia. The mean follow-up was 11 years. Cumulative survival was estimated using Kaplan-Meier analysis using the endpoint THA. Risk factors for THA conversion were identified using a multivariate Cox proportional hazards model.\n\n\nRESULTS\n40 patients underwent total hip arthroplasty (THA). Cumulative survivorship at 11 years was 86% for Toennis ≤ 1 and 46% for Toennis >1 patients. Osteoarthrosis, advanced age and female sex were associated with a lower hip survival. In particular, the risk of THA conversion was 24% higher for advanced age at the time of surgery, 97% higher for female patients, and 133% higher for Toennis grade >1 hips.\n\n\nCONCLUSION\nThe survivorship at mean 11-year follow-up after arthroscopic FAIS therapy was 86.3% and 46.4% for the Toennis grade ≤ 1 and Toennis grade > 1 group, respectively. The presence of osteoarthrosis, advanced age, and female sex adversely affected the outcome.\n\n\nLEVEL OF EVIDENCE\nLevel III, retrospective comparative study.
