RESUMEN
PURPOSE: To compare the clinical results of anterior cruciate ligament(ACL) reconstruction between the bone-patellar tendon-bone(BPTB) autograft and the allograft. MATERIALS AND METHODS: The clinical results of thirty-three patients of BPTB autograft and thirty-six patients of BPTB allograft performed between the periods of May 1994 and March 2004 were compared retrospectively in terms of Lysholm score, IKDC knee rating system, Tegner scale, physical examination, and KT-1000 arthrometry. Minimum follow-up period was 2 years(range: 24 to 144 months, average: 51.9 months). RESULTS: The postoperative Lysholm score at final follow-up was 89.4 in autograft group and 90.1 in allograft group on average. The difference between the two groups was not significant statistically in postoperative Lysholm score, IKDC knee rating system, and Tegner scale. Twenty-seven cases(81.8%) of autograft group had a negative Lachman test versus thirty-one cases(86.1%) of allograft goup, postoperatively. There was no significant difference in Lachman test, flexion-rotation-drawer(FRD) test, pivot shift test, and KT-1000 arthrometry between the two groups. CONCLUSION: The clinical results of ACL reconstruction using the BPTB autograft or allograft was equally good without statistically significant difference.
