Abstract: Aim: To evaluate whether the addition of a Lateral Extra-Articular Procedure (LEAP) to Anterior Cruciate Ligament Reconstruction (ACLR) yields superior outcomes compared to isolated ACLR. Design: Systematic literature review and meta-analysis Methods: Five databases were systematically searched for randomized controlled trials (RCTs) comparing ACLR with the addition of a LEAP versus isolated primary ACLR. Studies were included in meta-analysis when comparable outcome measures at equivalent time points were reported in at least two studies. Results: Fifteen RCTs were included in this review with ten eligible for meta-analysis. Metaanalysis demonstrated the addition of a LEAP significantly reduced rotatory instability (RR 1.45 [95%CI 1.17, 1.79]; p=0.0006) and graft rupture rates (RR 0.21 [95%CI 0.08, 0.55]; p=0.001). Short-term postoperative morbidity, including heightened pain, joint stiffness, and reduced muscle strength in the LEAP group, resolved by 6-12 months post-surgery. No association between LEAPs and accelerated knee osteoarthritis was identified. Conclusion: ACLR with the addition of LEAPs demonstrates superior clinical outcomes compared to isolated ACLR. Although early postoperative outcomes favoured isolated ACLR regarding pain and function, these effects resolved within 6-12 months. Current evidence remains insufficient to establish a relationship between LEAPs and accelerated knee osteoarthritis.
