[Indications and results of knee endoprostheses without an axis].

An analysis of 93 unconstrained totalcondylar knee prostheses showed good to excellent results. There was no significant difference between cemented and uncemented knee replacement. The advantages of unlinked totalcondylar knees are: --the minor bone resection, which enables a sure fixation of a new prosthesis or an arthrodesis in case of loosening, --the stabilisation by the natural ligaments leading to a reduced force transmission in comparison to linked prostheses. If knee replacement is necessary the total condylar surface replacement should be the knee endoprosthesis of first choice.
