title: Thirteen year results of total hip arthroplasty using a tapered titanium femoral component inserted without cement in patients with type C bone.
abstract: Although cementless arthroplasty with a tapered titanium femoral component has proven reliable in young patients with excellent bone quality, studies involving patients with poor bone quality are lacking. The present study evaluates the results of total hip arthroplasty (THA) using such a femoral component in patients with Type C femoral bone. Ninety-two THAs were performed in 81 patients aged 65 years and older using a tapered titanium cementless femoral component. Follow-up in 62 patients (72 hips) averaged 13.2 years (minimum, 10 years); 19 patients were lost to follow-up. According to Door's criteria, 20 femora were classified as Type A, 19 as Type B, and 33 as Type C. No stem was revised because of stem instability, thigh pain, or osteolysis. One stem was removed because of sepsis. Six acetabula were revised because of polyethylene wear and periacetabular osteolysis. Four patients reported mild thigh pain. Radiologic signs of osseous integration for cylindrical extensively porous coated cobalt-chrome femoral components are not valid for tapered titanium designs.
