RM Groningen, The Netherlands.
From a series of 135 patients (146 prostheses) who had had primary hip
replacement in 1975 and 1976 we reported the outcome at ten years in 83
surviving patients in 1988 and that at 15 years in 44 surviving patients
in 1994. Now, 22 years after the operation, we have reviewed the 21
patients who are still alive. Nineteen (20 hips) of these 21 patients
(22 hips) with a mean age of 85.7 years still had their original
prosthesis. Most patients were satisfied with the result, although the
level of activity in many was reduced because of increasing age and
other medical problems.
The stem was stable in all 20 hips. Only one cup was definitely loose.
Wear was observed in 40% of the cups but this was not a clinical
problem. At the 22-year follow-up the cumulative survival rate of the
prosthesis was 85%, of the stem 91% and of the cup 88%. Since 1975, 11
(7.5%) of the original 146 prostheses have been revised.
