Tibial slope after Medial Opening-Wedge High Tibial Osteotomy: Is plate positioning the biggest issue?
Objetive: One major cause of Medial Opening-Wedge High Tibial Osteotomy (MOW-HTO) failure is inadvertent Posterior Tibial Slope (PTS) increase. To avoid this complication, posterior placement of the wedge plate is traditionally recommended. However, in the attempt of achieving such positioning, surgeon may encounter some undesired consequences, like medial collateral ligament disruption, instab...
متن کاملAssessment of Tibial Slope Angle and Patellar Height after Medial-opening Tibial Osteotomy
OBJECTIVE To measure the variation in posterior tibial slope angle and patellar height in patients who underwent proximal tibial valgus-producing osteotomy using the medial-opening wedge technique. METHODS Anteroposterior panoramic radiographs of the lower limbs and lateral radiographs of the knee obtained before and after tibial valgus-producing osteotomy on 46 patients with unicompartmental...
متن کاملOpening wedge tibial osteotomy: the 3-triangle method to correct axial alignment and tibial slope.
BACKGROUND Although a change in tibial slope may occur during a medial opening wedge osteotomy, calculations have not been defined to address this problem. The authors investigated geometric factors important to correct axial alignment and tibial slope during osteotomy. PURPOSE To calculate, through 3-dimensional analysis of the proximal tibia, how the angle of the opening wedge along the ant...
متن کاملConventional plate and screws in medial opening-wedge high tibial osteotomy: are they sufficiently stable? A retrospective study☆
OBJECTIVE Opening-wedge osteotomy of the proximal tibia is a widely performed procedure for treating medial gonarthrosis in active patients and in the presence of varus malalignment of the lower limb. The fixation method is controversial, and the use of conventional implants has been abandoned in favor of implants with more modern locking screws. The aim of the present clinical study was to ass...
متن کاملEffect of Wedge Insertion Angle on Posterior Tibial Slope in Medial Opening Wedge High Tibial Osteotomy
BACKGROUND Medial opening wedge high tibial osteotomy (HTO) is a well-established surgery for medial compartment knee osteoarthritis (OA) wherein the lower extremity is realigned to shift the load distribution from the medial compartment of the knee to the lateral compartment. However, this surgery is known to affect the posterior tibial slope angle (PTSA), which could lead to abnormal knee kin...
