A Long-Term Follow-Up Of The STABILITY Study: Multicenter RCT Comparing Anterior Cruciate Ligament Reconstruction With And Without Lateral Extra-Articular Tenodesis In Individuals At High Risk Of Graft Failure
Abstract
One hundred and ninety-six patients at the Fowler Kennedy Sport Medicine Clinic (FKSMC) undergoing anterior cruciate ligament (ACL) reconstruction (ACLR) were randomized as part of the multi-center STABILITY study to receive either an isolated ACLR or ACLR with a lateral extra-articular tenodesis (LET). The STABILITY study followed these patients up to two years postoperative, and a long-term follow-up protocol was initiated afterwards. Eighty-two patients from this center were seen at three, five and seven years postoperative as part of a long-term follow-up. Our primary outcome was a composite outcome of instability and graft failure. Secondary outcomes included patient-reported outcome measures (PROMs), range of motion measurements, and adverse events. We found no statistically significant differences between groups for the composite outcome or the secondary outcomes, however there was a significant increase in graft rupture in the ACLR alone group. This thesis presents preliminary, single-center results of a long-term follow-up of the STABILITY study.
