Design outcomes

Primary

MeasureTime frame
To study the correlation between hip-knee-ankel angle, mechanical medial proximal tibial angle and mechanical lateral distal femoral angle measured by a) preoperative long leg radiographs b) intraoperative positioning of implants c) postoperative processing of data by engineers using exact measured cartilage thickness. Timepoint: Preoperative, Intraoperative and postoperative processing of data between 1-2 weeks after surgery—
