Since June 1979 we implant the RM isoelastic total hip endoprosthesis in younger patients (average age 53 years). Up to now 391 endoprostheses have been implanted. A follow-up examination of 60 operated hips in 55 patients 3 and 4 years after the implantation of the endoprosthesis was possible. In 46 hips there was no pain at all, in 12 hips a light or medium pain and in 2 hips a severe pain. 35 hips showed a range of motion of more than 90 degrees and between 30 degrees and 90 degrees. All patients were able to walk, 37 patients more than 1 hour. The patients declared the results of the operation in 50 hips to be very good or good, in 4 hips to be fair and in 6 hips to be poor. 5 times a potential loosening of the stem could be found.
