[Results with Guepar knee endoprostheses].

From 1977 to 1982 40 patients suffering from severe bilateral gonarthrosis, mostly caused by rheumatoid arthritis, underwent the implantation of 42 Guepar-endoprostheses of their knee joint. It was only in 1 case that a prosthesis got loose by infection and had to be removed without replacement. In 2 other cases of aseptic loosening a reimplantation of the prosthesis could be performed successfully. The authors emphasize the encouraging results.
