The noncemented collared stem had a significant reduction in periprosthetic femur fracture incidence compared to collarless stems.
Cumulative revision incidence was notably lower for the noncemented collared stem at 1.32%, compared to cemented and collarless cohorts.
Patients using the noncemented collared stem showed equivalent periprosthetic femur fracture rates compared to cemented alternatives.
Analysis utilized data from the American Joint Replacement Registry linked with Medicare claims, covering over 90,000 cases.
