Is Cementless Acetabular Fixation an Improvement in Total Hip Arthroplasty Performed in Younger Patients?

Especially in the young patient, cemented acetabular fixation in the total hip arthroplasty (THA) construct has had limited long-term durability. For this reason, the 2 senior authors began using cementless acetabular components in 1986. The authors address the question, “Is the durability of cementless acetabular fixation greater than cemented fixation in younger patients (age 50 years and younger) at 10- to 18-year follow-up?”
