The effect of lateral opening wedge distal femoral osteotomy on medial knee opening: clinical and biomechanical factors

Purpose The case of a patient with knee valgus and instability due to combined ACL–MCL laxity who under- went lateral opening wedge distal femoral osteotomy (DFO) is presented. The symptoms of instability resolved following the surgery. It was unclear whether the increase in valgus stability was related only to a decrease in valgus moments during stance or also to a medial tensioning effect. We therefore performed a laboratory cadaveric study. The purpose of this study was to examine whether after MCL and ACL sectioning, lateral opening wedge DFO would result in decrease in medial opening under static conditions of valgus stress.
