We present 251 Ring uncemented plastic on metal (UPM) hip replacements with a follow-up of 2-5 years. Judging the functional results by the Harris hip evaluation for the surviving 234 hips, 79.8% were good to excellent, 11.7% fair, and 8.5% poor at an average of 3 years. The mortality within one month of surgery was 0.79%. There were 4 cases of deep infection (1.59%), 3 of which required excision arthroplasty. At 3 years, 6 hips (2.39%) had required revision, all for aseptic femoral loosening, 2 of which also had acetabular loosening. Ring UPM hip is both safe and reliable in the hands of many surgeons outside Ring's unit.
