Cemented Femoral Component Use in Hip Arthroplasty

Area of Science:

• Orthopedic Surgery
• Biomaterials Engineering
• Geriatric Medicine

Background:

• Elderly patients represent a growing demographic undergoing hip arthroplasty, increasing healthcare costs.
• National registries indicate a lower revision surgery risk for cemented femoral components in patients over 75.
• Despite evidence, cementless implants are increasingly used in elderly hip arthroplasty patients.

Purpose of the Study:

• To evaluate the comparative effectiveness of cemented versus cementless femoral components in elderly hip arthroplasty.
• To highlight the benefits of cemented fixation in challenging bone conditions.
• To emphasize the importance of surgical technique in achieving durable implant fixation.

Main Methods:

• Analysis of data from national joint replacement registries.
• Comparison of revision surgery rates between cemented and cementless femoral components in patients >75 years.
• Review of advancements in cementing techniques and cemented stem design.

Main Results:

• Cemented femoral components are associated with a lower risk of revision surgery in elderly patients (>75 years).
• Non-cemented components have a higher incidence of early periprosthetic femoral fracture.
• Decades of improvements in cementing techniques ensure reliable fixation even in poor bone quality.

Conclusions:

• Cemented femoral components remain a reliable option for hip arthroplasty in the elderly, particularly for revision risk reduction.
• Surgeons must possess a thorough understanding of cement properties, bone preparation, and stem design for successful cemented fixation.
• Optimizing cementing techniques is essential for achieving durable outcomes in hip arthroplasty for the aging population.
