[Complications after replacement of a knee joint endoprosthesis with a cementless "low contact stress" prosthesis]

Total endoprosthesis of the knee joint of the LCS type reduce due to the mobile placement of the menisci and rotatable components the mechanical demands on anchoring in bone and thus contribute to satisfactory biological integration. During the period between June 1, 1989 and December 31, 1991 in the orthopaedic department of the general hospital in Zwettel 41 patients had 42 total endoprostheses (LCS) of the knee joint implanted. The group comprised 34 women and 7 men. All patients were checked and evaluated according to Hungerdorf's schema. The age range was 62 to 79 years with an average of 65.8 years. The follow-up period was 8 to 38 months, mean 21 months. The results as regards pain, stability, mobility, axis of the extremity and ability to walk were evaluated as very good and good. The authors discuss also postoperative complications. They did not observe loosening of cement-free components.
