Abstract
Sixty-one consecutive patients (68 hips) with an average age of 49.7 years (range, 21–72 years) had the Freeman uncemented hip arthroplasty without HA coating performed in the Southern General Hospital between 1987 and 1990. These patients were reviewed retrospectively for a mean duration of 66 months (range, 3–103 months). A high incidence of significant thigh pain (40.4%) at 5 to 8 years was noted in this series. The average 5- to 8-year femoral subsidence was 5.4 mm (range, 0–16.1 mm) in 45 hips. Seventeen hips (29.3%) required revision at the time of analysis. Nine hips (15.5%) were revised for aseptic loosening at an average duration of 54 months after the index operation. The conclusion drawn from this series is that the Freeman press- fit hip produced unsatisfactory medium-term results.
