201 hips with the Harris-Galante Porous (HGP) system and 41 hips with Hybrid system were compared both clinically and radiographically. According to the radiogram taken at follow-up, radiopaque lines around the stem, which is called "clear zones", were frequently seen in zone 4, 10, 11 or 12. It was likely that the patients did not have thigh pain when these clear zones appeared exclusively in zone 4, 10, 11, or 12. On the other hand, however, the patients seemed to have thigh pain when the clear zones also appeared in other areas and zone 4, 10, 11, or 12. Thirty-six patients (23%) with osteoarthritis who had HGP system complained of thigh pain. In the group with Hybrid system, only two patients (6%) had thigh pain. However, this thigh pain in the HGP group had a tendancy to disappear gradually and remained in only two patients (6%). Sinking and micromovement of the stem may be one of the causes of the thigh pain.An optimal method for fixation of the femoral component has not been established. The results obtained from our short-term follow-up showed that smaller number of patients had thigh pain in the group of HGP system in comparison with previous reports. However, long-term follow-up study may be still necessary to draw some definite conclusion upon this matter.
