A prospective study was done of the intermediate-term clinical and
radiographic results of 121 total hip arthroplasties in which a
Harris-Galante porous titanium-fiber-coated prosthesis was inserted without
cement in 110 patients. The average age at the time of the operation was
forty-nine years (range, twenty to seventy years). The average duration of
follow-up was sixty-seven months (range, fifty-five to seventy-nine
months). The average preoperative Harris hip score was 55 points, and the
average postoperative score was 93 points. One acetabular component was
revised due to recurrent dislocation. Eleven femoral implants were
unstable, and of these, four were revised. Cortical erosion was present
around the distal part of the femoral stem in nine patients (8 per cent)
who had stable implants, and one of these femoral implants was revised
because the erosion was extensive. Survivorship analysis at five years
revealed a 97 per cent chance of survival (95 per cent confidence limit,
0.937 to 1.0) of the Harris-Galante femoral-stem implant inserted without
cement.
