Minimum clinical and roentgenographic follow- up was five years and averaged 5.9 years. Three hips were revised for aseptic loosening of the femoral component.
All acetabular components remain stable.
Average Harris Hip Score of the surviving hips was 93 points at last follow-up. Three characteristic patterns of femoral bone remodeling were observed, indicating favorable adaptation of the femur to a proximally porous-coated implant.
