  • Purpose: To estimate the initial and early phase fixation power of the human bone interference screw in reconstruction of the anterior cruciate ligament with bone-patellar tendon-bone allograft. Materials and Methods: The results of twenty eight knees of reconstruction with bone-patellar tendon-bone allograft were analysed in 6 weeks, 12 weeks, 6 months and one year following operation. Physical examination including Lachman test, flexion rotation drawer test and jerk test were performed. The KT-1000 measurement was performed at the same time. In Lachman test 0 $\~$2mm anterior displacement of the tibia was considered normal. The KT-1000 measurement of normal side was compared with operation side and the difference of the two was recorded. The MRI was checked at final follow-up. Results: All but one knee showed normal in physical examination. The failed case showed proximal migration of the graft due to insufficient number of interference screw fixation in widened tibial tunnel. Conclusions: The human cortical bone interference screw showed sufficient initial and early phase fixation power in reconstruction of the anterior cruciate ligament.
