title: Revision hip arthroscopic surgery: outcome at three years.
abstract: OBJECTIVE
  This study describes the medium-term results of revision hip arthroscopy.
  
  
  METHODS
  Patients with persistent hip pain and a positive impingement sign were considered for revision surgery after the exclusion of other causes of groin pain. Seventy-four consecutive patients were prospectively assessed using the modified Harris hip score for a period of 3 years after surgery. Of the 74 patients, 11 had inadequate follow-up data; thus, a total of 63 patients were qualified for the study. The mean age at index surgery was 37 years, comprising 27 males and 36 females.
  
  
  RESULTS
  Revision surgery was performed at a mean of 3 years from index surgery. Chondral lesion associated with labral re-injury was the most common finding at revision arthroscopy. In contrast to other authors, however, only 31 % of our patients underwent revision for persistent femoroacetabular impingement. The mean pre-operative mHHS for all 63 patients was 54 (SD 14.5). The mean post-operative mHHS was 53 (SD 14.9) at 6 weeks, 62 (SD 17.5) at 6 months, 63 (SD 16.5) at 1 year, 64 (SD 16.5) at 2 years and 59 (SD 16.5) at 3 years (p = n.s., 0.02, 0.045, 0.039 and n.s., respectively).
  
  
  CONCLUSIONS
  Revision arthroscopy results in improvement in outcome in the first 3 years after revision surgery with a success rate of 63.4 % at 1 year, falling to 55.6 % by 3 years.
