[Long-term clinical and radiological results of entirely hydroxyapatite-coated femoral components].
OBJECTIVE
To evaluate the clinical and radiological results of entirely hydroxyapatite (HA)-coated femoral prosthesis.


METHODS
Thirty-five patients aged 59.7 (32 -79), underwent total hip arthroplasty using HA-coated femoral prosthesis, 32 of which were followed up for 10.2 (9.7-10.9) years. Harris scoring and X-ray examination were used to evaluate the clinical and radiological results.


RESULTS
The symptoms of all the patients were alleviated. One patient complained nonspecific discomfort in groin area, and 2 patients showed mild limp. One patient had to undergo pure repair of acetabulum 7 years later. No thigh pain was seen in other cases. The mean Harris score 10 year after operation was 87.70 +/- 7.73, significantly higher than that before operation (39.20 +/- 8.88, P < 0.05). No case of aseptic loosening was found. X-ray examination showed no osteolysis and radiolucent line. Subsidence of prosthesis was found in 3 cases; however, with a distance less than 2 mm. The 10-years survivorship of the entirely HA-coated prosthesis was 100%.


CONCLUSIONS
Entirely HA-coated total hip prosthesis has an excellent clinical and radiological long term results.
