| Research Abstract |
Pelvic bone adaptation around the acetabular component (cup) after cementless total hip arthroplasty was evaluated using quantitative computed tomography technique. Acetabular cancellous bone around the cup decreased as much as -36% at one year after operation. On the other hand, the decrease was moderate betweenone-year and two-year evaluation. In contrast, there was tiny bone density change in the cortical bone. We observed neither osteolytic lesion nor loosening of the cup at two years after operation. The changes of load transfer pattern may affect the remodeling of pelvic bone around the cup after total hip arthroplasty.
