Limb alignment after open-wedge high tibial osteotomy and its effect on the clinical outcome.

The purpose of this study was to evaluate the accuracy of alignment after open-wedge high tibial osteotomy and its effect on the clinical outcome. A prospective case series of 56 consecutive patients underwent open-wedge high tibial osteotomy fixed with a TomoFix plate fixator (Synthes, West Chester, Pennsylvania). The correction angle was radiologically determined preoperatively and at 6 months postoperatively.

Assessment of correlation between knee notch width index and the three-dimensional notch volume.

This study was done to determine whether there is a correlation between the notch volume and the notch width index (NWI) as measured on the three most frequently used radiographic views: the Holmblad 45 degrees, Holmblad 70 degrees, and Rosenberg view. The notch volume of 20 cadaveric knees was measured using Computed Tomography (CT). The Holmblad 45 degrees, Holmblad 70 degrees, and Rosenberg notch view radiographs were digitally re-created from the CT scans for each specimen, and the NWI was measured by two observers.
