Abstract

BackgroundThere are two primary surgical techniques to reconstruct the anterior cruciate ligament ACL, transtibial TT technique and anteromedial portal AMP technique. Currently, there is no consensus which surgical technique elicits the best clinical and functional outcomes. MRI-derived measures of the signal intensity SI of the ACL graft have been described as an independent predictor of graft properties. The purpose of this study is to compare the MRI derived SI measurements of the ACL graft one year after ACL reconstruction, in order to compare the outcomes of both the AMP and TT ACL reconstruction technique.

Methods-designThirty-six patients will be included in a randomized controlled trial. Patients who are admitted for primary unilateral ACL reconstruction will be included in the study. Exclusion criteria are a history of previous surgery on the ipsilateral knee, re-rupture of the ipsilateral ACL graft, associated ligamentous injuries or meniscal tear of the ipsilateral knee, unhealthy contralateral knee, contra-indications for MRI and a preference for one of the two surgical techniques and-or orthopaedic surgeon. Primary outcome is MRI Signal intensity ratio SIR of the ACL graft. Secondary outcome measures are the International Knee Documentation Committee IKDC Knee Examination Form,the Knee injury and Osteoarthritis Outcome Scores KOOS and the Anterior Cruciate Ligament OsteoArthritis Score ACLOAS. Differences between MRI SIR assessment with the current MRI protocol proton density weighted imaging protocol and the additional T2*-weighted gradient-echo protocol will be assessed.

DiscussionThere is no consensus regarding the TT or AMP ACL reconstruction technique. SI measurements with MRI have been used in other clinical studies for evaluation of the ACL graft and maturation after ACL reconstruction compared to clinical and functional outcomes. This randomized controlled trial has been designed to compare the TT technique with the AMP technique with the use of MRI SI of the graft after ACL reconstruction.
