Anterior Cruciate Ligament Revision Plus Lateral Extra-Articular Procedure Results in Superior Stability and Lower Failure Rates Than Does Isolated Anterior Cruciate Ligament Revision but Shows No Difference in Patient-Reported Outcomes or Return to Sports

摘要

? 2022 Arthroscopy Association of North AmericaPurpose: To determine whether comparative clinical studies demonstrate significant advantages of revision anterior cruciate ligament reconstruction (RACLR) combined with a lateral extra-articular procedure (LEAP), with respect to graft rupture rates, knee stability, return to sport rates, and patient-reported outcome measures, compared with isolated RACLR. Methods: A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews & Meta-Analyses Guidelines. A PubMed search was conducted using the key words “revision anterior cruciate ligament reconstruction” combined with any of the following additional terms, “lateral extra-articular tenodesis” OR “anterolateral ligament reconstruction” OR “Lemaire.” All relevant comparative clinical studies were included. Key clinical data were extracted and evaluated. Results: Eight comparative studies (seven Level III studies and a one Level IV study) were identified and included. Most studies reported more favorable outcomes with combined procedures with respect to failure rates (0%-13% following RACLR+LEAP, and 4.4%-21.4% following isolated RACLR), postoperative side-to-side anteroposterior laxity difference (1.3-3.9 mm following RACLR+LEAP and 1.8-5.9 mm following isolated RACLR), and high-grade pivot shift (0%-11.1% following RACLR+LEAP and 10.2%-23.8% in patients following isolated RACLR). There were no consistent differences between isolated and combined procedures with respect to return to sport or patient-reported outcome measures. Conclusions: This systematic review demonstrates that the addition of a LEAP to RACLR was associated with an advantage with respect to ACL graft failure rates and avoidance of high-grade postoperative knee laxity across almost all included studies. Level of Evidence: IV, Systematic review of level III to IV studies.
