NCT00431509

Brief Summary

This study is undertaken to investigate the effect of navigated knee implantation surgery on physical function, joint stiffness, pain, quality of life and coordinative abilities. One group of patients will receive navigated knee implantation surgery, the other traditional knee implantation surgery, without use of the navigation system. The study is designed as a randomized trial. That means that all patients who have given their consent to participate in this study will be allocated to either navigated or conventional surgery by chance. A total of 477 patients will be included in this study and will be followed up for 12 month. In this period all patients will be asked to fill in functional and quality of life questionnaires at baseline, 6 weeks and 3, 6 and 12 month follow-up. Coordinative abilities will be evaluated once in the time-frame 3 to 6 months postoperatively.
