Abstract :

BACKGROUND : The purpose of the study was to find out effect of autologous hamstring tendon graft size on patient reported outcomes following Arthroscopic Anterior cruciate ligament ( ACL ) reconstruction .METHODS: A retrospective review of prospectively collected cohort data of 90 patients who had primary ACL reconstruction using hamstring tendon autograft were evaluated. Patients age , sex , graft diameter at the time of surgery and minimum of 2 years post-operative functional outcome were assessed using Tegner Lysholm Knee Scoring Scale ( TLK ) , Knee Injury and Osteoarthritis Outcome Score (KOOS) , and International Knee Documentation Committee ( IKDC) score . Mean of TLK, IKDC and KOOS scores were calculated along with that of graft diameter. Pearson correlation coefficient was calculated to find out relation between graft diameter and the three individual scores independently. Two-tailed test was used to compute the statistical significance of parameter inferred from data set.RESULT: There was a positive linear correlation between graft diameter and the three subjective scores independently. However 2 tailed test for statistical significance was significant only for TLK and KOOS scores. CONCLUSION: We found statistically significant correlation between hamstring autograft graft diameter and TLK and KOOS scores. We conclude that hamstring autograft diameter is one of the important predictor for postoperative functional outcome and a good functional outcome can be predicted with thicker graft diameter.
