Abstract

Introduction

In a prospective randomized study, we compared the results after implantation of the mobile bearing high flex TKA with a fixed bearing posterior stabilized TKA in 60 patients (30 patients each group).

Method

We evaluated the hospital for special surgery-score (HSS) and different radiological parameters preoperatively, as well as 3 months, 3 and 5 years postoperatively.

Result

Three months postoperatively, the high flex group showed better results in scores for pain, ROM (122.5° vs. 107.33°), as well as in the overall HSS (87.21 vs. 82.68 points). Three and 5 years postoperatively, there were no differences between both the groups in all scores, but the HSS is still increasing.

Conclusion

The theoretical advantages of the mobile bearing knee prostheses were reflected in the clinical results, only partly and temporarily.
