ABSTRACT

Objective To compare the clinical outcomes of anterior cruciate ligament(ACL)reconstruction by using allograft and autograft of patella tendon.Methods From August 2003 to December 2005,82 ACL reconstruction patients were studied retrospectively,including 59 cases using autograft of patellar bone-tendon-bone(BPTB)and 23 cases using BPTB allograft.Physical examination,scores of IKDC,Lysholm-Tegner and VAS as well as KT-2000 measurements were used for evaluation pre-and post-operation.Results 41 autograft and 17 allograft patients were finally followed up.One allograft patient suffered re-rupture of the reconstructed ligament.Positive ADT test were found in 5 autograft and 1 allograft patients and positive Lachman test were found in 3 autograft and 1 allograft patients.No statistically significant differences were revealed in ROM.IKDC,Lysholm-Tegner Score and KT-2000 measurements showed no significant differences between two groups,but VAS for autograft group were significantly higher than allograft group(P
