Summary
First clinical and radiographic results with a new knee joint prosthesis, implanted without cement, are reported and the characteristics of the implant (dowel fixation and special instrumentation) presented. The first series of 35 joints with a follow-up period of 1–3 years shows excellent results. Radiographically, primary osseous integration cannot be positively identified in all cases, but it could be proved in most instances. Cement-free implantation requires good preoperative bone quality and an operative technique which inserts the implant anatomically. If these two conditions are met, there is every probability of successful implantation. No problems specific to the implant have been encountered.
