title: Long-term follow-up of patients with geomedic prostheses.
abstract: Of 122 Geomedic arthroplasties performed, 85 were possible to follow up. The mean observation period was 58 months. The original position of the prosthesis was analyzed with respect to its effect on the clinical condition. A score system was used for this purpose. A normal alignment was obtained in 51%. No statistically significant correlation could be shown between a high radiographic score and a high clinical score. A resorption zone of 2mm or more, considered a sign of loosening, arose in 37% and a coexisting change of position in 12%. There is no difference in radiographic score between the prostheses which were judged as loose and the other prostheses. Twelve percent of the patients were reoperated because of loosening. The patients consider their condition to be very good or good in 93% of cases. Pain at rest and pain on weight bearing were totally absent in 87% and 72% of cases respectively.
