Clinical Results of Anterior Cruciate Ligament Reconstruction: Bone-Paterllar-Tendon-Bone vs Hamstring Tendon Autograft

ABSTRACT

PURPOSE: To compare the clinical and radiologic results of the anterior cruciate ligament(ACL) recon- struction between bone-patellar tendon-bone autograft and doubled semitendinosus and gracilis autograft. MATERIALS AND METHODS: 45 patients out of 235 ACL reconstructions with bone-patellar tendon- bone(BPTB) autograft and 47 patients out of 178 ACL reconstructions with doubled semitendinosus and gracilis were included in this study. Average follow-up period were 19 months in BPTB autograft and 17 months in doubled semitendinosus and gracilis autograft. There were no differences in preoperative parameters(age, sex, instability). RESULTS: There were no significant differences between two groups with respect to functional result(Lysholm knee score), degree of laxity and range of motion at final follow-up. However, the parap- atellar complications, especially anterior knee pain after long distance walking or exercise, and quadriceps weakness were less occurred in doubled semitendinosus and gracilis autograft than in BPTB autograft. CONCLUSION: ACL reconstruction with doubled semitendinosus and gracilis autograft is a good alternative choice in reducing parapatellar complications and in achieving functional stability of knee joint.
