5-to 8-year results of the Freeman press-fit hip arthroplasty without HA coating - A clinicoradiologic study

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 mont hs (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 femora l 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 revise d 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.
