MEDIAL OPENING WEDGE HIGH TIBIAL OSTEOTOMY USING THE PUDDU PLATE WITH GRAFT IN PATIENTS WITH Genu Varum

Abstract

Genu varum is a common deformity associated with medial compartmental osteoarthritic knee with subsequent mechanical axis deviation and stress disturbances across the knee joint with medial compartmental loading which is aggravated by adduction moment during gait. This varus deformity is pathologically started by varus instability then become fixed varus deformity of the osteoarthritic knee. Varus instability is either due to pathological bone changes or ligamentous elongation or both. Fixed varus deformity could be attributed to collapse of the bone medially with contracture of the medial soft tissues. Preoperative measurements of the degrees of varus deformity is so essential to overcorrect the deformity and putting the knee in net valgus position 5 degrees to shift the arc of the body weight to the healthy lateral compartment which is better done with CT – scanogram of both lower limb.
