Application of allogeneic bone-tendon-bone in reconstruction of knee cruciate ligament

Abstract

Objective To investigate the efficacy of allogeneic bone-tendon-bone for reconstruction of anterior and posterior cruciate ligaments of knee. Methods Twenty-two cases were subjected to the reconstruction of anterior and posterior cruciate ligaments of knee using allogeneic bone-tendon-bone, including 21 males, and 1 female with age of 22-53 years old (mean 36.7 years old). The left knee was affected in 13 cases, and the right knee in 9 cases. The patients were evaluated subjectively (Lysholm score before and after operation) and objectively (using Lachman test and axial shift test). Results Twenty-one patients were followed up for 5-42 months (mean 23.3 months), and one patients lost the follow-up. Before operation, Lysholm scores were 19.6±3.6 (15-30), and those at the last follow-up were 83.9±16.2 (41-99), which were significantly different from those before operation (t=20.440, P=0.002). Except one case of graft loosing, the rest cases had negative or improved Lachman test and axial shift test. No complications occurred in all patients. Conclusion The clinical use of allogeneic bone-tendon-bone for reconstruction of cruciate ligaments of knee can avoid the re-injury caused by autologous materials and corresponding complications.
