Brief Summary
50 patients are randomized to two groups who receive a navigated knee prosthesis. Aim of the study is a comparison between a minimally invasive and a conventional approach. In both groups OrthoPilot computer assisted-navigation will be used. Pain intensity as well as concomitant pain medication are monitored during the first 20 postoperative days and will be compared for the two groups. Various scores are surveyed.
