Abstract
Anterior closing wedge osteotomies (ACWO) are utilized to better restore knee stability and in situ forces on anterior cruciate ligament (ACL) grafts during ACL revision reconstruction while reducing the risk of retearing and subsequent revision procedures. However, clinical outcomes following ACWO for patients undergoing ACL reconstruction remains largely limited. The purpose of this review was to provide a concise overview of the current literature on indication, techniques, and outcomes following ACWO in ACL-deficient patients undergoing primary or revision ACL reconstruction while discussing the authors' preferred technique to ACWO during a staged ACL revision reconstruction. Currently available clinical studies and case reports have demonstrated ACWO to improve knee stability and outcomes for patients with an increased posterior tibial slope undergoing primary or revision ACL reconstruction with low complication rates. The ACWO provides an adjunct surgical option to decrease graft failure while improving knee stability and post-surgical outcomes for patients with an increased posterior tibial slope undergoing primary or revision ACL reconstruction. Further investigations are warranted to validate currently reported outcomes following ACWO in higher-level clinical studies with longer-term follow-up.
