title: [Surgical treatment of posteromedial corner injury combined with cruciate ligament rupture of knee].
abstract: OBJECTIVE
  To investigate the methods and effectiveness of surgical treatment for posteromedial corner (PMC) injury combined with anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) ruptures.
  
  
  METHODS
  Between February 2009 and February 2012, 15 patients (15 knees) with PMC injury combined with ACL and PCL ruptures underwent PMC repair with suture anchor and ACL and PCL reconstruction. There were 7 males and 8 females with an average age of 39 years (range, 15-59 years). The causes of injury were traffic accident injury in 6 cases, sport injury in 7 cases, and sprain injury in 2 cases. The disease duration was 3-15 days with an average of 7 days. All patients presented positive results of anterior drawer test, posterior drawer test and valgus stress test, and dysfunction of knee joint. Of 15 cases, 3 had ACL and PCL ruptures, 5 had ACL rupture, 3 had ACL injury at the attachment point of the condyles crest, and 4 had PCL rupture; 9 had PMC tear at the femur insertion, 5 had PMC tear at the tibia insertion, and 1had PMC tear in the body area.
  
  
  RESULTS
  All incisions healed by first intention with no complication of infection or stiffness of knee. All cases were followed up 18.4 months on average (range, 10-36 months). At last follow-up, 14 cases had normal knee flexion and extension ranges, but 1 case had 10 degree limitation of the knee extension. Except 1 case which had weakly positive valgus stress test, the other patients showed negative results of anterior drawer test, posterior drawer test, and valgus stress test. Based on the improved Lysholm classification standard, the results were excellent in 8 cases, good in 5 cases, and fair in 2 cases; the excellent and good rate was 86.7%.
  
  
  CONCLUSIONS
  Early repair of the PMC and reasonable reconstruction of cruciate ligament can effectively restore the knee stability for patients with PMC injury combined with ACL and PCL ruptures.
