Change in Posterior Tibial Slope After Open-Wedge and Closed-Wedge High Tibial Osteotomy A Meta-analysis

摘要

Background: It is unclear whether open-or closed-wedge high tibial osteotomy (HTO) results in significant changes in posterior tibial slope, with no consensus on the magnitude of such changes. Furthermore, methods of measuring posterior tibial slope differ among studies. This meta-analysis was therefore designed to evaluate whether posterior tibial slope increases after open-wedge HTO and decreases after closed-wedge HTO and to quantify the magnitudes of the slope changes after open-and closed-wedge HTO using various methods of measuring posterior tibial slope.
