Introduction As endpoint of a prospective multicenter 10-year documentation using the Columbus system, this evaluation carried out results of clinical scores (Knee Society Score and Oxford Knee Score), an evaluation of radiological imaging, survival rates and a collection of complication statistics. Materials and methods There was a multicenter prospective recruitment of consecutive patients with the indication for total knee replacement (TKR). Preoperatively and 10 years after implantation, clinical scores, range of motion and radiological imaging was performed. During this period, a detailed documentation of complications was made. Results A total of 210 patients were recruited in 5 centers. 140 patients were available for endpoint examination 10 years after surgery. A survival rate of 96.6% (CI 95%) for the implanted Columbus prostheses after 10 years was demonstrated. Cumulative KSS showed an improvement of 75.3 (± 38.1) points and was highly significant ( p  &lt; 0.0001,  t  test). The average functional improvement in the Oxford score was 20.6 (± 9.5) points and was also highly significant ( p  &lt; 0.0001). The ROM improved from 106.5° (± 20.5) preoperatively to 116.0° (± 11.5) ( p  &lt; 0.0001,  t  test). There were no implant-related complications as well as no new complication documented between 5- and 10-year follow-up. Conclusions The endpoint analysis after an observation period of 10 years provided good clinical and radiographic results. In particular, an excellent survival rate of 96.6% after 10 years was demonstrated. The data published in this study are the first to be available in a prospective multicenter study on this system, which leads to a high level of clinical significance.
