[Low contact stress knee prosthesis system. Results and complications]

This paper reports on the global results of the low contact stress knee prosthesis system with mobile weight bearing surfaces. The follow-up result of 918 cemented and 963 cementless knee prostheses was in more than 90 per cent excellent and good 2-8 years after the operation. The ratio of complications connected with the construction decreased to 2.8 per cent in cementless prostheses. In the cemented series less variations of size were available and the problems with the tibial component were under 2, the complications with the patella remained under 1 per cent. The more than 12 years clinical use of the mobile weight bearing knee prosthesis system proved the success of the solution concerning the basic construction.
