title: [Etiological analysis and significance of anterior knee pain induced by gluteal muscles contracture].
abstract: OBJECTIVE
  To explore causes of gluteal muscle contracture induced anterior knee pain and curative effect of arthroscopic release.
  
  
  METHODS
  From March 2002 to August 2013,36 patients with gluteal muscle contracture induced anterior knee pain were treated, including 15 males, 21 females, aged from 9 to 40 years old with an average (18.7±7.2) years old; the courses of diseases ranged from 4 to 30 years. The clinical manifestations involved limited to symmelia, positive Ober sign, buttocks touch contracture belts, knee and patella slide to lateral when doing squat activities. All patients were performed gluteal muscle contracture release under arthroscopic. Postoperative complications were observed, Kujala scoring before and after operation was used for compare curative effect.
  
  
  RESULTS
  All patients were followed up with an average of 29 months. The incision were healed well, and no complications were occurred. Postoperative Kujala score were improved more than preoperative.
  
  
  CONCLUSIONS
  Gluteal muscle contracture release could alleviate hypertension of lateral patella, and palys an important role in preventing patellofemoral arthritis.
