Between November 1984 and December 1989, 318 non‐cemented Porous Coated Anatomic (PCA; How‐medica, Rutherford, New Jersey) total hip replacements were performed by the authors. A follow‐up of 1 to 6 years was allowed. The average age was 53.1 years (from 17 to 71 years). The distribution of right‐to‐left was approximately equal. There were 192 hip replacements for primary and post‐traumatic osteo‐arthritis, 42 for rheumatoid arthritis, 40 for avascular necrosis, 29 for congenital dislocation or hip dysplasia with secondary osteo‐arthritis, 6 for Perthes disease, 5 for previous sepsis, 2 of whom had had a Girdlestone procedure, 2 for revision of a painful cup arthroplasty, and 1 for conversion of a previously fused hip. All patients were evaluated on a one hundred point Harrington Arthritis Research Centre Scale. Points were awarded for pain (0–35), function (0–35), motion (0–10), deformity (0–10) and gait (0–10). Pre‐operative total scores averaged 45.5 (9–71) and postoperative scores averaged 83.9 (55–98). The overall results were excellent 20.5% (90–100), good 59.8% (80–90), fair 16.4% (70–80), and poor 3.3%. Postoperative radiographs were evaluated using zonal analysis. There was no deterioration on the radiographs after two years.
