ABSTRACT: Objective: The primary objective of this investigation was to assess the survivorship of acetabular components in total hip arthroplasty in patients aged 50 and under when comparing cemented and uncemented implantation methods over a 10-year period. Patients and Methods: This prospective cohort study used data from a regional registry. The study identified all THRs performed on patients aged 50 and under, with 10-year postoperative follow-up data. Patients required a minimum 10-year follow-up, and the all-cause revision rate for the acetabular component was calculated. A follow-up rate of 92.6% was achieved. Results: A total of 364 THRs were identified from 2005 to 2010. The cases were categorised into two groups: those with cemented acetabular components (n = 93), and those with an uncemented acetabular component (n = 227). The observed revision rate of the cemented acetabular component THR was 5.4%, in contrast to the revision rate of the uncemented acetabular component, which was 4.4% (p > 0.05). The mean time to revision for these two groups was found to be 4.4 years and 4.6 years, respectively (p > 0.05). Conclusion: This study discerns no difference between cemented and uncemented methods in THRs conducted on patients aged 50 and under, with regard to all-cause revision rates for acetabular components.
