Collared vs Collarless Femoral Stems for Hip Replacement Surgery
What You Need to Know Before You Apply
What is the purpose of this trial?
This is a prospective randomized control trial comparing two collared and collarless femoral implants used in primary total hip arthroplasty. The specific aims of this trial are to:
SA1: Prospectively assess clinical outcomes in patients undergoing primary total hip arthroplasty with a collared versus collarless femoral stem of the same design.
SA2: Evaluate serial radiographs to quantify differences in subsidence between collared and collarless implant groups.
SA3: Report and compare incidence rates of intraoperative and postoperative periprosthetic fractures and aseptic loosening following primary total hip arthroplasty with use of either a collared or collarless stem.
Hypothesis: The addition of a collar to the same designed triple-taper primary hip stem will lead to a reduction in subsidence and incidence of perioperative and periprosthetic femur fractures.

Trial Overview
The study compares two types of femoral implants: one with a collar and one without, in hip replacement surgeries. It aims to assess clinical outcomes, measure implant subsidence through X-rays, and track fracture rates post-surgery.
