자가 슬괵건과 동종 전경골건을 이용한 전방 십자 인대 재건술의 임상적 결과 비교

Abstract

Purpose: The purpose of this study is to compare the clinical results of ACL reconstruction between two groups using hamstring tendon autograft and tibialis anterior tendon allograft. Materials and Methods: Between January 2006 and June 2007, we analyzed 68 cases of ACL reconstruction, 32 cases using hamstring tendon autograft and 36 cases using tibialis anterior tendon allograft, with a minimum follow-up of 24 months. For the clinical evaluation, we evaluated the Lysholm score, anterior laxity by Telos device and KT-2000 arthrometer. Results: The mean diameter of graft were 8.0 mm (7.0~9.0 mm) in autograft group and 9.1 mm (8.0~10.0 mm) in allograft group. In all cases, the range of motion was above 135 degrees. The average side to side difference in Telos stress test decreased from $7.3{\pm}1.0$ mm to $2.4{\pm}1.1$ mm in autograft group and from $7.4{\pm}1.2$ mm to $2.3{\pm}1.3$ mm in allograft group. The average Lysholm knee score improved from $72.6{\pm}3.4$ to $92.3{\pm}3.5$ in autograft group and from $72.3{\pm}3.5$ to $91.6{\pm}3.3$ in allograft group. There was no significant difference between two groups in clinical results. Conclusion: Both hamstring tendon autograft and tibialis anterior tendon allograft groups showed satisfactory clinical results, with no significant difference in outcomes between the groups. We suggest that both hamstring tendon autograft and tibialis anterior tendon allograft will be considered as acceptable graft for anterior cruciate ligament reconstruction
