Does ACL Augmented With LEAT Better Controls Rotational Laxity Than Isolated ACL Reconstruction?

2019-10-28 13:56:51 | BioPortfolio


It has been suggested that adding a Lateral Extra-Articular Tenodesis (LEAT) to Anterior Cruciate Ligament (ACL) reconstruction has the advantage of better controlling the rotational laxity. The objective of this study is to compare the the sagittal and rotational knee laxity using the Porto Knee Testing Device (PKTD) - a MRI-compatible arthrometer - at 2 years follow-up (side-to-side and to baseline comparison) in patients that underwent isolated ACL reconstruction (isolated ACL) versus ACL reconstruction combined with LEAT (ACL+LEAT). Patient-reported outcome measures using the Knee Injury and Osteoarthritis Outcome Score (KOOS) and graft failure (re-tear) will also be assessed at 2 years follow-up.


This study is a non-randomized clinical trial including 40 patients with anterior cruciate ligament injury who are undergoing surgery and will be allocated 1:1 to either isolated ACL reconstruction (control group) or ACL reconstruction combined with lateral extra-articular tenodesis (experimental group). The principal outcome of this work is the sagittal and rotational knee laxity analysis and side-to-side and 2-year improvement. The secondary outcomes include graft failure (re-tears) and the patient-reported outcome measures (KOOS) at 2 years follow-up.
