Triple-Taper Collared Stem Morphology Influences Periprosthetic Femoral Fracture Risk: A Comparison of Single-, Dual-, Triple-, and Quadrangular-Taper Stems.

BACKGROUND: Stem morphology is an important contributor to periprosthetic femoral fracture (PFF) risk following total hip arthroplasty (THA). New-generation triple-taper collared stems may be associated with a lower risk of PFF. Our objective was to…
