Area of Science:

  • Orthopedic surgery
  • Biomaterials science
  • Medical device analysis

Background:

  • Total ankle replacement (TAR) offers satisfactory outcomes, but the Ankle Evolutive System (AES) implant has a high revision rate.
  • Periprosthetic osteolysis, characterized by cortical lesions and bone cysts, is a primary cause of AES TAR failure.
  • Histological analysis reveals foreign particles in peri-implant tissues, suggesting material wear contributes to adverse reactions.

Purpose of the Study:

  • To investigate the wear mechanisms of the Ankle Evolutive System (AES) total ankle replacement (TAR) implant.
  • To identify the most stressed components of the AES implant.
  • To characterize the nature and size of foreign body particles generated by the implant.

Main Methods:

  • Retrospective analysis of 10 retrieved Ankle Evolutive System (AES) total ankle replacement (TAR) implants.
  • Microstructural analysis of implant components.
  • Tomographic analysis of implant parts and periprosthetic tissues.

Main Results:

  • Identification of specific wear patterns on AES implant components.
  • Characterization of foreign particle morphology and size distribution.
  • Correlation between implant wear, particle generation, and periprosthetic osteolysis.

Conclusions:

  • Understanding implant wear and particle generation is crucial for explaining the in vivo behavior of the AES TAR.
  • Findings provide insights into friction mechanisms and material degradation.
  • This research can inform the design of future, more durable ankle prostheses.
