title: A five to seven years follow-up of 102 cementless Synatomic knee arthroplasties.
abstract: One hundred and two cementless Synatomic total knee prostheses were implanted in our hospital between January 1987 and October 1989. All knees were retrospectively followed up for five to seven years and examined for both pre- and postoperative clinical or radiological factors indicating aseptic loosening. The overall survival of the implants was 88.6%. The mean preoperative tibiofemoral angle of 178.5 degrees was found to be corrected immediately postoperatively to 183.4 and at the latest review to 182.3 degrees, with a slight shift towards varus which in the case of femoral component further increased during follow-up (P < 0.05). No correlation was found between tibiofemoral alignment and overall joint survival. Improvement of the preoperative marked (over 12 degrees) tibiofemoral valgus alignment correlated to clinical failure (P < 0.05). No such correlation was observed in pronounced varus knees (P = 0.897). A clear correlation was observed between the clinical outcome and the knee joint (P < 0.05) and function (P < 0.05) scores. Especially pain correlated closely with survival.
