A comparative study on functional outcome of ACL reconstruction: Quadriceps versus hamstring tendon autograft

Abstract

IntroductionThere are various soft tissue graft options available for anterior cruciate ligament reconstruction. This study aims to compare the functional outcome following anterior cruciate ligament reconstruction between quadriceps tendon and hamstring tendon autografts. HypothesisThere was no significant difference in functional outcome of anterior cruciate ligament reconstruction between quadriceps and hamstring tendon autografts at two years follow up. MethodsOut of total 96 patients in our study, 48 patients included in quadriceps tendon autograft group and remaining 48 patients included in hamstring tendon group. Both group of patients were treated by same surgeon, with similar fixation methods and criteria for functional outcomes includes IKDC scores and clinical assessment of stability at 2 years follow up. ResultsPreoperative IKDC scores in quadriceps and hamstring tendon group are 56 and 58 respectively. Out of 48 patients in quadriceps tendon group 4 patients lost for follow up and out of 48 patients in hamstring tendon group 6 patients lost for follow up at 12 weeks. At 2 year follow up IKDC scores in quadriceps tendon group is 114 in 40 patients and 100 in 4 patients(mean IKDC score 113), in hamstring tendon group is 119 in 38 patients and 113 in 4(mean IKDC score 118) with p value > 0.05(p = 0.97) showing no statistical significance. ConclusionOur study shows no statistical significant difference between quadriceps and hamstring tendon autograft groups at 2 years follow up following anterior cruciate ligament reconstruction. This shows our hypothesis was correct.
