Comparative Study On Forepart Clinical Effects Of Patellar And Hamstring Tendon In Arthroscopy Assisted Anterior Cruciate Ligament Reconstruction

Objective: The purpose of this investigation was to evaluate replacement of anterior cruciate ligament with either a patellar tendon autograft or 4 strands of hamstring tendon autograft to compare the result of clinical testing,patients satisfaction,activity level,function status,Lysholm-tegner score and KT-1000 testing.Method: One hundred and fifty patients were divided randomly into 2 groups. 76 cases of group A with autograft of patellar tendon (n=76);74 patients of group B with autograft hamstring tendon (n=74). All procedure were performed endoscopically by some surgeons. All patients were followed up at 3 ,6,9, 12 months.Results: There were statistically significant differences revealed in physical examination. Lysholm-tegner score and jump test as well as KT-1000 testing was used preopration and postopration for both group, but there were no significant differences between the two groups in postopration.Conclusions: Anterior knee pain following anterior cruciate ligament reconstruction with patellar tendon has to be higher than that following reconstruction with hamstring tendon. The 4 strands of hamstring tendon autograft were similar to anatomic anterior cruciate ligament since the fixation of technique was improved in reconstruction. The objective results of anterior cruciate ligament reconstruction with hamstring tendon were superior to those of replacement with patellar tendon autograft in forepart,but there were no significant differences between the two groups in long-term. This suggested that hamstring tendon had good biomechanic characteristics. The operating technique of arthroscopic ACL reconstruction with hamstring tendon had benefits of less complications and operation injuries,reliable fixation and clinical outcomes.
