Arthroscopic Wire Fixation of Avulsion Fractures of the Posterior Cruciate Ligament from the Tibia

Backgound:ligament advanced reinforcement system is a graft choice for ligament reconstruction,we used ligament advanced reinforcement system Y-shape double bundles to reconstruction the posterior cruciate ligament,it's necessary to know the clinical effect of this technique. Method:A retrospective analysis was conducted among 11 patients with posterior cruciate ligament injuries, who were enrolled from Department of Orthopaedics in Guangzhou General Hospital of Guangzhou Military Area Command of Chinese PLA from January to July in 2007. Arthroscopic reconstructions of posterior cruciate ligament were performed by using the ligament advanced reinforcement system (LARS) Y-shape bundles artificial ligament. Y-shape double cords of LARS artificial ligament were fixed at 90°and 30° flexion respectively. All 11 patients received the follow-ups. Result:There were no complications occurred, such as synovitis, ligament rupture or limited motion. X-ray results proved the extrused screws were positioned well. Posterior drawer test, Lachman’s test and pivot shift test were negative after surgery. According to the international knee documentation committee activity grades, grade D were 8 cases and grade C were 3 cases preoperatively; while grade A were 10 cases and grade B was 1 case postoperatively, with the significant differences (χ2=9.142, P < 0.05). The clinical assessment judging by lysholm knee functional scoring system showed that, average scores before operation was (65.2±5.6) and increased to an average of (90.7±3.6) postoperatively (t=10.572, P < 0.05). Conclusion:LARS artificial ligament is good grafts for posterior cruciate ligament reconstruction, can do early functional exercise and have good clinical effect.
