The ceramic cup type Lindenhof

We followed up 10–14 years postoperatively the 106 ceramic cups type ‘Lindenhof’ that were implanted in the years 1978–1982. In that time, only 7 (6.6%) cups had to be changed due to aseptic loosening. Examination of 73 (68.9%) cups showed that only 4% of the patients were disatisfied. Using the score of Merle d'Aubigne, we found 89% good and very good results. The high number of cup migrations reported by other authors could not be verified: we saw 35% in all. Most of them appeared in the early postoperative period, stabilized themselves and were not accompanied by pain. Our 10-year survival rate for this ceramic cup is 92%, including the septic changing of arthroplasties.
