title: [Cannulated screw fixation through posteromedial approach screw for the treatment of tibial avulsion fracture of the tibial attachment of the posterior cruciate ligament].
abstract: OBJECTIVE
  To explore therapeutic effects of cannulated screw fixation through posteromedial approach for the treatment of tibial avulsion fracture of the tibial attachment of the posterior cruciate ligament.
  
  
  METHODS
  From February 2007 to March 2012, 36 patients with tibial avulsion fracture of the tibial attachment of the posterior cruciate ligament were reviewed. Among the patients, 28 patients were male and 8 patients were female, ranging in age from 16 to 57 years old,averaged 35 years old. All fractures were fresh closed fracture. The posterior drawer test and heavy sign were positive in all patients. AP X-ray of knee joints of all patients showed avulsion fracture flaps at the posterior tibia platform. All the patients were treated with cannulated screw fixation through posteromedial approach, and function exercise performed after operation. The Lysholm criterion was used to evaluate clinical effects.
  
  
  RESULTS
  All the patients had successful operation, and were followed up. The duration of follow-up ranged from 6 to 36 months, with an average of 12 months. The fractures healed at 3 months after operation. According to Lysholm knee joint evaluation criteria, 30 patients got an excellent result, 4 good and 2 poor,the average score was 92.2 +/- 3.8.
  
  
  CONCLUSIONS
  Cannulated screw fixation through posteromedial approach for the treatment of tibial avulsion fracture of the tibial attachment of the posterior cruciate ligament is effective to recover joint function to large extent, which is a safe, simple and effective surgical method.
