Simultaneous Correction of Varus Deformity and Posterior Tibial Slope by Modified Hybrid Closed-Wedge High Tibial Osteotomy.

ABSTRACT: A large posterior tibial slope has been proven to be a risk factor for anterior cruciate ligament (ACL) injuries, ACL graft failure, and medial meniscus posterior root tear. In addition, such pathologies often are accompanied by varus alignment. Thus, simultaneous varus and slope-correction osteotomy is required in such cases. High tibial osteotomy (HTO) is a well-established treatment for medial compartment knee osteoarthritis. Several HTO surgical techniques have been proposed, and hybrid closed-wedge HTO has been found to correct both varus deformity and a large posterior tibial slope via modification of the transverse osteotomy procedure. This Technical Note describes a modified hybrid closed-wedge HTO for simultaneous varus and slope correction in patients with ACL deficiency and/or medial meniscus posterior root tear involving both varus deformity and a large posterior tibial slope. This technique may reduce the risk of failure of the ACL graft and/or repaired medial meniscus posterior root.
