Abstract
Purpose: Ninety-six patients who underwent hydroxyapatite coated cementless total hip arthroplasty during the period from January 1992 to December 1994 were evaluated.
Patients and methods: Clinical assessment using Harris hip score showed that mean preoperative value was 42 points (range 21-79 points), while postoperative value at the last follow-up was 90 points (range 51-100 points). Radiographic analysis were based on DeLee and Charnley criteria for the acetabular component and Gruen criteria for the femoral component.
Results: Four acetabular component were revised during the follow-up period because of the aseptic loosening. There was no femoral osteolysis and no femoral component revision was performed until last follow-up. Thigh pain was percent in 14.2% of the hips and persisted up to 2 years.
Conclusion: At the last control, our clinical results were better than radiographic results and we concluded that hydroxyapatite coating is a good option for cementless hip prosthesis.
