[Clinical results using the PM type of hip endoprosthesis]

The results of clinical follow-up examinations of cement-free PM total hip replacements implanted between March 1981 and December 1985 are reported. Of 231 PM hips, 125 were re-examined. Questionnaires were completed by 58 patients who were not examined. With an average value of 15.7 points according to Merle d'Aubigné, the overall clinical results may be regarded as good. A total of 86.4% of the patients stated that their condition was better than before surgery. However, almost 20% had severe complaints. These included on the one hand soft-tissue complaints, in particular in the immediate postoperative phase; on the other, in cases with initially minor sinking-in of the shaft and subsequently more than 5 mm, there was a high level of significance in the correlation to the complaints which occurred. No problems occurred with the screw-in acetabulum.
