[Intermediate results of kinematic knee prosthesis]

A retrospective study of 88 of 117 kinematic total knee prostheses was carried out at the Department of Orthopaedics, University Clinic, Innsbruck. In 71 cases the clinical and functional score of the knee Society was applied. Radiographs were taken under fluoroscopic control. In 3 cases, the need for revision surgery was already obvious. A slight varus angle of 2.1 degrees became apparent. Flexion contracture showed a correlation with the inclination of the femoral component. Radiolucencies of the tibial component showed up in cases with a reduced tibial angle. Radiolucencies of the patella component correlated with lateral subluxation.
