This study details a custom-made tibial implant for extensive bone defects, enabling total knee arthroplasty in a patient with severe knee instability. Future production may improve with PEEK materials.

Area of Science:

  • Orthopedic surgery
  • Biomedical engineering
  • Materials science

Background:

  • Psoriatic arthritis can lead to severe knee instability and bone destruction.
  • Extensive tibial defects often preclude the use of standard prosthetic components.
  • Custom-made implants offer a solution for complex bone reconstruction.

Observation:

  • A 65-year-old male patient presented with a 20-year history of psoriatic arthritis and severe right knee varus deformity.
  • Radiography revealed extensive destruction of the medial tibial condyle and involvement of the lateral condyle.
  • The defect size necessitated a custom implant, as commercial options were unsuitable.

Findings:

  • A custom-designed titanium tibial implant was developed using 3D modeling from CT scans.

The Use of Mixed Reality in Custom-Made Revision Hip Arthroplasty: A First Case Report

Published on: August 4, 2022

  • The implant's geometry was verified on a plastic model before manufacturing.
  • The custom implant was successfully used to complete a total knee arthroplasty.

    • Implications:

    • Custom implants provide a viable solution for extensive tibial defects in knee reconstruction.
    • Future advancements may involve using materials like poly-ether-ether-ketone (PEEK) to streamline production.
    • This approach enhances functional restoration for patients with complex orthopedic conditions.
