Correction of varus deformity with tibial flip autograft technique in total knee arthroplasty.

摘要

A simple method of autogenous bone grafting is described for correction of varus deformity during total knee arthroplasty. This technique uses a wedge of bone resected from the proximal tibia, which is flipped to augment the medial compartment. It is recommended in osteoarthritic knees with 15 degrees to 20 degrees of varus angular deformity resulting from peripheral rim tibial defects involving the medial compartment. This method corrects varus deformity, preserves bone stock, and creates a stable platform for seating of tibial components without the need for internal fixation.
