Background: High tibial osteotomy can affect the posterior tibial slope in the sagittal plane because of the triangular configuration of the proximal tibia. However, the effect of the location of cortical hinge on posterior tibial slope has not been previously described.
Hypothesis: Posterolateral location of the cortical hinge will increase posterior tibial slope after medial open wedge osteotomy, and lateral location of the cortical hinge will not affect the change of the posterior tibial slope. Read More

Background And Purpose: The aim with high tibial valgus osteotomy (HTO) is to correct the mechanical axis in medial compartmental osteoarthritis of the knee. Loss of operative correction may threaten the long-term outcome. In both a lateral closing-wedge procedure and a medial opening-wedge procedure, the opposite cortex of the tibia is usually not osteotomized, leaving 1 cm of bone intact as fulcrum. Read More

Purpose: The objective of this study was to quantify the effect of different loading axes and of a valgus opening wedge high tibial osteotomy (HTO) on tibiofemoral cartilage pressure.
Methods: Six human knee specimens were tested with a load of 1000N in extension in a materials testing machine using a specially designed fixture. Pressure in the medial and lateral joint compartment was recorded using pressure-sensitive films. Read More

Purpose Of The Study: When a larger opening of high-tibial osteotomy is necessary to achieve good correction of the lower extremity axis, partial release of the attachments of the medial stabilisers of the knee may be required. The aim of the study was to ascertain, in cadaver specimens, the effect of loosening the medial knee stabilisers on the magnitude of correction in medial opening-wedge high-tibial valgus osteotomy.
Material And Methods: Thirty-eight knees obtained from cadavers of Caucasian race were dissected. Read More
