Patellar height and tibial slope after opening-wedge proximal tibial osteotomy: a prospective study.
BACKGROUND Further knee surgery after proximal tibial osteotomies has been reported to have a more difficult surgical exposure due to decreased patellar height after the osteotomy. Although a decrease in patellar height has been reported for closing-wedge proximal tibial osteotomies, it has not been widely verified among opening-wedge procedures. HYPOTHESIS A significant decrease in patellar ...
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...
متن کاملPosterior tibial slope in medial opening-wedge high tibial osteotomy: 2-D versus 3-D navigation.
Although opening-wedge high tibial osteotomy (HTO) is used to correct deformities, it can simultaneously alter tibial slope in the sagittal plane because of the triangular configuration of the proximal tibia, and this undesired change in tibial slope can influence knee kinematics, stability, and joint contact pressure. Therefore, medial opening-wedge HTO is a technically demanding procedure des...
متن کاملAnterior opening wedge high tibial osteotomy: the effect of increasing posterior tibial slope on ligament strain.
BACKGROUND Although a previous study showed that anterior opening wedge high tibial osteotomy (HTO) for sagittal plane correction induced no increased strain in the anterior cruciate ligament (ACL), we hypothesized that other ligamentous restraints of the knee may be subjected to increased strain. METHODS We mounted 6 cadaveric knees at 15 degrees flexion in a testing apparatus that provided ...
متن کاملTibial 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...
