Medial Open‐Wedge High Tibial Osteotomy for Double Varus Deformity and an Increased Tibial Slope

This is the authors' abstract. We don't add key points for this paper.

The goal of the modified medial open-wedge high tibial osteotomy is the combined correction of a double varus deformity (mechanical medial proximal tibia angle <84°, joint line convergence angle >2°) and an increased posterior tibial slope >12°. This goal can be achieved through a few modifications to the standard biplanar medial open-wedge high tibial osteotomy technique. These modifications include (1) positioning of the hinge anterolaterally and above the fibula, (2) removing a small anterior wedge, and (3) using Schanz screws to facilitate slope correction. Osteosynthesis is performed with a locking plate. Rehabilitation involves 6 weeks of partial weight-bearing and free range of motion.
