Description
Introduction
Despite being a largely successful surgery, some patients experience residual anterolateral rotatory instability (ALRI) and re-rupture after ACL reconstruction. LEAT, has been shown to reduce reinjury, resolve ALRI and improve graft healing1,2,3,4. LEAT has become a popular procedure consequently. Recent studies have shown both improved and delayed graft maturity with the addition of a LEAT3,5.
Objective
To study the effects of LEAT on ACL graft healing and integration using High Resolution MRI scan
Conclusion
Literature states both improved and delayed graft healing with the addition of LEAT to ACL reconstruction. Tunnel widening is a frequently encountered phenomenon with ACL reconstruction especially with hamstring grafts8. Tunnel widening is described as a multifactorial process; however, it is known that LEAT reduces tibiofemoral rotational forces which could reduce motion at the graft-tunnel interface and synovial fluid tunnel propagation, thereby reducing graft tunnel widening. Our study does have limitations. there is a limited sample size, a younger study population (mean age 18 years), The Howell and Ge Scoring are observer dependant, and there was a potential selection bias as risk evaluation for the indication for LEAT was by one senior surgeon .
