ABSTRACT

Background: The success of hip arthroplasty is heavily influenced by the choice of femoral stem, with proximally coated and fully coated uncemented stems being common options. This study compares their clinical and radiographic outcomes to guide optimal selection. Methods: A retrospective analysis evaluated clinical scores (Modified Harris Hip Score, Oxford Hip Score, Forgotten Joint Score) and radiographic outcomes (porous interfaces, spot welds, interface deterioration) of patients with proximally vs. fully coated uncemented femoral stems over a midterm follow-up period. Results: Proximally coated stems demonstrated slightly higher functional scores and a longer mean survival time (4 years) compared to fully coated stems (3.056 years). Interface deterioration was more common in the fully coated group, suggesting potential long-term stability concerns. Conclusion: The study suggests proximally coated uncemented femoral stems may offer superior pain management, functional recovery, and longevity. The choice between stem types should consider individual patient needs and the potential for long-term challenges. Personalized selection is crucial for optimizing outcomes in hip arthroplasty.
