At the I. Orthopadischen Klinik des BRK-Rheumazentrums Bad Abbach/Regensburg, Deutschland, 37 of a total of 357 monocondylar sliding prostheses were exchanged for total endoprotheses during the period from January 1977 to December 1989. These reoperations, which generally did not entail any essential technical difficulties during surgery, became necessary in the first four years in about two-thirds of the cases. Today we realise that this had been due to a too liberal indication for that particular type of prosthesis. Mild ligamental instabilities or destructions of the contralateral compartments had not been regarded as contraindications because of the wish to avoid employing total endoprostheses in the - often young - rheumatic patients. During the same period, 23 of 561 GSB total endoprostheses and another five total endoprostheses of the knee joint of various types that had been implanted elsewhere, were exchanged. Infections, especially late infections, proved an essential problem, now treated by us with a two-stage prosthesis exchange after some unfavourable experiences with arthrodeses. Occasionally we had to use custom-made prostheses because of extensive bone defects after removal of the prostheses. Compared with the septic complications, no major difficulties are encountered when exchanging aseptically loosened prostheses. Fractures near the prostheses can be successfully treated by extending the pedicle of the prosthesis resulting in a compound osteosynthesis with intramedullary load support. Implant fractures are of secondary importance; two GSB prostheses and one GUEPAR prosthesis had to be exchanged because of such fractures. In case of patellar dislocations caused by malimplantations it may be better to exchange the prosthesis than to resort to other measures to achieve patellar medialisation.
