Cementless acetabular components in total hip arthroplasty offer superior radiographic performance. Newer porous metal surfaces show promise for enhanced bone ingrowth and implant durability.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Biomedical Engineering

Background:

  • Aseptic loosening is the primary cause for revision total hip arthroplasty (THA).
  • Cementless acetabular components, relying on biologic fixation, gained popularity over cemented options due to better radiographic outcomes.
  • Optimal acetabular fixation methods for THA remain a subject of ongoing research and debate.

Purpose of the Study:

  • To review and compare various cementless acetabular fixation surfaces used in total hip arthroplasty.
  • To evaluate the bone ingrowth potential and long-term durability of different implant materials.
  • To highlight emerging porous metal technologies for acetabular component fixation.

Main Methods:

  • Review of existing literature on cementless acetabular component fixation in THA.

Published on: September 7, 2022

  • Comparison of commonly used surface treatments: fibermesh, sintered beads, and plasma spray coatings.
  • Analysis of emerging porous metal technologies, including porous tantalum and Tritanium.

    • Main Results:

    • Titanium fibermesh shows a 1% mechanical failure rate at 10-15 years.
    • Sintered bead fixation demonstrates long-term durability.
    • Titanium plasma spray exhibits durability, even with osteolysis.
    • Porous tantalum and Tritanium show potential for enhanced bone ingrowth and mechanical strength.

    Conclusions:

    • Cementless acetabular components require initial stability for bone ingrowth and long-term prosthesis durability.
    • Various surface treatments, including fibermesh, sintered beads, and plasma spray, offer different levels of bone ingrowth and fixation.
    • Emerging porous metal technologies like porous tantalum and Tritanium present promising advancements in acetabular component design for improved biologic fixation and mechanical performance in THA.
