title: Hip arthroscopy for Legg-Calvè-Perthes disease: minimum 2-year follow-up.
abstract: OBJECTIVE
  The purpose of this study is to report the results of arthroscopy for the treatment of adolescents and adults with hip pain cause by sequelae of Legg-Calvè-Perthes disease.
  
  
  METHODS
  All patients undergoing hip arthroscopy were prospectively assessed with the modified Harris Hip Score at 3, 6, 12, 24, 60, 120, and 180 months. We identified a cohort of 22 consecutive patients (23 hips) with Legg-Calvè-Perthes disease who had undergone arthroscopy with at least 2-year follow-up; this cohort represents the substance of this report.
  
  
  RESULTS
  There was 100% follow-up at 24 months (range, 24 to 180 months). The median age was 27 years (range, 7 to 58 years) with 14 male and 8 female patients. Findings during arthroscopy included 18 labral tears, 17 hypertrophic or torn ligamentum teres, 9 femoral and 8 acetabular chondral lesions, 5 loose bodies, 3 osteochondral defects, and 2 cam lesions. The mean improvement at 24 months was 28 points (56.7 preoperatively and 82 postoperatively). All patients were improved, although this improvement was negligible in 2 patients who underwent repeat arthroscopy. There were no complications.
  
  
  CONCLUSIONS
  This series reports the results of arthroscopy for Legg-Calvè-Perthes disease and reflects that it does have a role in the management of painful sequelae. Successful outcomes can often be expected with minimal morbidity. Reduced symptoms and improved quality of life are reasonable expectations, although these data do not suggest that hip arthroscopy alters the natural history of the disease process.
  
  
  METHODS
  Level IV, therapeutic case series.
