Primary uncemented total hip arthroplasty in patients <40 years old: 10- to 14-year results using first-generation proximally porous-coated implants.

Eighty-two consecutive primary first-generation uncemented total hip arthroplasties (72 patients) performed in patients <40 years old were reviewed with minimum follow-up of 10 years. Of 82 hips, 24 (29.3%) have been revised to date. The estimated survival free of aseptic revision or radiographic failure was 81.3% at 10 years for the acetabular components. The estimated survival free of aseptic revision or radiographic failure was 84.9% at 10 years for the femoral component. In this exclusively young patient cohort, there was a high failure rate of the acetabular component and the femoral component. The data in this report can serve as a baseline for comparison of newer implants and operative methods.
