title: [Clinical classification of gluteal muscle contracture under arthroscopy].
abstract: OBJECTIVE
  To explore clinical effects of gluteal muscle contracture and minimum invasive surgery under the arthroscopy.
  
  
  METHODS
  Totally 358 patients with gluteus contracture were treated,which included 175 males and 183 females with an average age of (19.7 +/- 6.8) years old (ranged, 14 to 41). All patients have a history of repetitive intramuscular injection of penicillin with benzyl alcohol solvent. According to clinical characteristics and intraoperative situation, patients were classified into four groups:cable strip (118 cases), fanshaped (107 cases), mixed (87 cases), tensor fasciae latae contracture(46 cases). The curative effects were evaluated according to postoperative function evaluation standard of gluteus contracture.
  
  
  RESULTS
  All patients were followed up and 37 cases withdrew. The following up time ranged from 1.5 to 8 years with an average of 3.5 years. According to evaluation standard of gluteus contracture, 303 cases got excellent results, 13 cases good,and 5 cases fair at the final follow-up. No recurrence, infection and neurovascular injury occurred.
  
  
  CONCLUSIONS
  The classification of gluteal muscle contracture is beneficial for choose surgical strategy and improve curative effect. The advantage of plasma knife minimally invasive solution in treating gluteal muscle contracture with radiofrequency under arthroscopy is minimally invasive, safe, and benefit for early functional exercises.
