Abstract:

BACKGROUND: Allogeneic tissue transplantation has become a choice of ligament graft and reconstruction, and allogenic bone-patellar tendon-bone graft is a method for lateral collateral ligament reconstruction.
OBJECTIVE: To investigate the clinical effect of allogenic bone-patellar tendon-bone graft for chronic lateral collateral ligament injury.
METHODS: From April 2008 to December 2009, 11 cases of Ⅲ degree chronic lateral collateral ligament injury were selected and treated with lateral collateral ligament reconstruction by allogenic bone-patellar tendon-bone graft.
RESULTS AND CONCLUSION: All patients were followed-up for 12-15 months. The wound healed by first intention. The movement ranges of the knee were significantly increased preoperatively (P < 0.05). The Lysholm scroe at the last follow-up was significantly increased as compared with preoperatively. Preoperative varus stress radiographs demonstrated the knee lateral joint space increase of 8 to 20 (12.9±3.5) mm in average compared with the contralateral, the knee lateral joint space was 2-3 (1.0±1.9) mm at 6 months postoperatively, and there was a significant difference (P < 0.05), and there was no significant difference when compared with the healthy side (P > 0.05). Reconstruction of the lateral collateral ligament with allogenic bone-patellar tendon-bone graft is a viable option to treat chronic lateral collateral ligament tears, and can restore normal varus stability, and plays a protect effect on other soft fissue repair.
