Questionnaire: Femoroacetabular impingement (FAI) leads to hip pain and osteoarthrosis. The gold standard of treatment is the surgical hip dislocation with labrum reattachment performed since 2001. We investigated the 5-year outcome of this procedure and calculated predective factors for poor outcome.
Methods: We retrospectively evaluated 97 hips (75 patients) that underwent surgical dislocation at a mean age of 32±8.3 (range, 15 50) years. The average follow-up was 6.0 0.6 (5.0 7.1) years. Preoperatively, the mean Merle d´Aubign (MDA) score was 15.3±1.4 (8 18) and the mean Tnnis osteoarthosis (OA) score was
The cumulative survivorship at 5 years was 93.8% (95% confidence interval, 89.0 98.6%). At followup, the MDA score was significantly increased to 17.2 1.2 (12-18) (p=0.02) and the Tnnis score did not significantly increase to 0.22 0.46 (0-2). Failure was defined as conversion to a total hip arthroplasty (THA), a MdA score of less than 15, and a progression of OA at follow up.0.29 0.55 (0 - 2) (p=0.56). Failures (15 hips, 15%) included 7 hips (7%) that converted to a THA, 7 hips (7%) with progression of OA, and 1 hip (1%) with a MDA score of less than 15 at followup.
Results and Conclusions: Surgical hip dislocation has the potential to prevent the progression of osteoarthrosis and to decrease hip pain in patients with FAI.
