Description
Introduction: Anterior cruciate Ligament (ACL) injuries are common among athletes and active individuals. Following ACL reconstruction with an autograft tendon, functional outcomes are often assessed using a Lysholm Score, an inventory of patient function. Purpose: This study compares autograft tendons-quadriceps tendon (QT), hamstring tendon (HT), or patellar tendon (PT) to determine the relationship between the tendon donor site and average Lysholm Scores.
Methods: a meta-analysis was conducted on studies involving individuals aged 18 and older who underwent ACL reconstruction with HT, QT, or PT. A logic transformation of semi-quantitative outcomes was applied using generic inverse variance in both common and random effects models. Chi-square analyses for intergroup and intragroup comparisons were used. Heterogeneity and tau statistics were generated using both the common effects effect model.
Results/Discussion: Based on the common effect model are as follows: HT 90% [88%;92%], QT 92% [91%;93%], and PT 91% [91%;92%]. These findings suggest that there may be a modest benefit to using the QT as the donor site; all appear to be comparable across the 24-month follow-up period, leading to the conclusion that symptomatic outcomes do not appear to depend heavily on the tendon donor site. Based on the findings of this analysis, metrics other than Lysholm Scores may better guide clinical decision-making when selecting graft tendon donor sites.
