Abstract Increasingly young and active patients are undergoing total hip arthroplasty, making hip prosthesis survival rates an important issue. Cementless total hip arthroplasty provides better prosthesis longevity than does cemented hip arthroplasty, especially in younger patients. Because there is growing support in the literature for tapered geometry in cementless femoral components, we evaluated short-term results for total hip arthroplasty using Cementless Spotorno (CLS) titanium stems. We performed 100 consecutive primary cementless total hip arthroplasties in 87 patients during a 9-year period using CLS stems. Outcome was assessed in terms of survival rate and Harris Hip Score.
The stem survival rate was 99%, and the average Harris Hip Score improved from 41 before surgery to 92 at a mean point of 5 years after surgery. Only 1 hip underwent stem revision for a periprosthetic shaft femur fracture caused by high-velocity trauma from a vehicle accident that occurred 6 months after the original surgery. The CLS stems have an excellent survival rate in the short term, especially in younger patients, but long-term studies are required to provide a fuller picture.
