Abstract:

BACKGROUND: Using autologous tendon graft to reconstruct the knee cruciate ligament has been widely applied, but the technique has shortages such as donor site prone to complications, relatively longer operation time and greater trauma. So allogeneic tendon grafts have been applied as an important alternative materials in reconstructing knee cruciate ligament more and more frequently.
OBJECTIVE: To compare the clinical efficacy difference between using autologous tendon and allograft tendon to reconstruct knee cruciate ligament under arthroscopy.
METHODS: We had divided 40 cases of cruciate ligament injury into two groups: Group autologous tendon of 21 cases in which autogenous semitendinosus and gracilis muscle was used to reconstruct knee anterior and posterior cruciate ligament, while Group allograft tendon of 19 cases receiving allograft tendon provided by the Shanxi Province Bone Allograft Tendon Tissue Bank.
RESULTS AND CONCLUSION: All the patients were followed up for 6 to 36 months. There was statistical significance in contralateral thigh circumference difference, Lachman test, anterior drawer test in neutral position and the International Knee Documentation Committee scoring, Lysholm and Tegner scores between the two groups before and after surgery (P < 0.01). All the indexes showed no significant difference in the same group after surgery (P > 0.05). There was no significant difference in clinical efficacy between autologous tendon and allograft tendon with a simple deep-frozen tendon in anterior and posterior cruciate ligament reconstruction.
