title: Arthroscopic labral repair versus selective labral debridement in female patients with femoroacetabular impingement: a prospective randomized study.
abstract: OBJECTIVE
  The purpose of this prospective randomized study was to compare the outcomes of arthroscopic labral repair and selective labral debridement in female patients undergoing arthroscopy for the treatment of pincer-type or combined pincer- and cam-type femoroacetabular impingement.
  
  
  METHODS
  Between June 2007 and June 2009, 36 female patients undergoing arthroscopic hip treatment for pincer- or combined-type femoroacetabular impingement were randomized to 2 treatment groups at the time of surgery: labral repair or labral debridement. The repair group comprised 18 patients with a mean age of 38; the debridement group comprised 18 patients with a mean age of 39. All patients underwent the same rehabilitation protocol postoperatively. At a minimum of 1 year, all patients were assessed using a validated Hip Outcome Score (HOS) to determine hip function, and also completed a simple subjective outcome measure.
  
  
  RESULTS
  All 36 patients were available for follow-up at an average time of 32 months (range, 12 to 48). In both groups, HOSs for activities of daily living (ADL) and sports improved significantly from before surgery to the final follow-up (P < .05). The postoperative ADL HOS was significantly better in the repair group (91.2; range, 73 to 100) compared with the debridement group (80.9; range, 42.6 to 100; P < .05). Similarly, the postoperative sports HOS was significantly greater in the repair group (88.7; range, 28.6 to 100) than in the debridement group (76.3; range, 28.6 to 100; P < .05). Additionally, patient subjective outcome was significantly better in the labral repair group (P = .046).
  
  
  CONCLUSIONS
  Arthroscopic treatment of femoroacetabular impingement with labral repair in female patients resulted in superior improvement in hip functional outcomes compared with labral debridement. In addition, a greater number of patients in the repair group subjectively rated their hip function as normal or nearly normal after surgery compared with the labral debridement group.
