Robotically Assisted Anterior Closing Wedge High Tibial Osteotomy: A Surgical Technique Proof of Concept.

ABSTRACT: Increased posterior tibial slope is a risk factor for anterior cruciate ligament reconstruction graft failure. In revision anterior cruciate ligament surgery, anterior closing-wedge high-tibial osteotomy (ACW-HTO) addresses increased tibial slope. ACW-HTO is technically challenging in accurately executing the desired bony cuts and degree of correction. Risks include posterior neurovascular injury, hinge fractures, coronal-plane alterations, and over/under alignment correction. We present a technique leveraging the accuracy of a computed tomography-based robotic knee arthroplasty system to plan and execute precise bone cuts for ACW-HTO. We carried out 3 ACW-HTO scenarios on a Sawbones model; supratubercle, infratubercle, and combined coronal plane osteotomy. After Sawbones computed tomograp
