title: 5- to 8-year results of the Freeman press-fit hip arthroplasty without HA coating: a clinicoradiologic study.
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.
