Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Medical Imaging

Background:

  • Patient-specific instrumentation (PSI) technology aims to enhance precision in uni- and bicompartmental knee replacements.
  • PSI utilizes virtual 3D joint models derived from MRI or CT scans for pre-operative planning.
  • The technology produces custom guides to translate surgical plans into operative procedures.

Purpose of the Study:

  • To describe the planning and surgical technique of MRI-based PSI in knee replacement.
  • To evaluate the efficacy of PSI compared to conventional techniques using own results and literature.
  • To assess outcomes including surgical time, component fit, and alignment.

Main Methods:

  • A prospective comparative study involving 88 patients undergoing total knee arthroplasty (TKA).
  • 44 patients received MRI-based PSI, while 44 received conventional techniques.
  • Key metrics compared: surgical trays, operating time, intraoperative modifications, and frontal alignment via full leg X-ray.

Main Results:

  • PSI allowed for precise detection of anatomical abnormalities preoperatively.
  • Reduced surgical tray requirements and improved predictability of component size were observed with PSI.
  • PSI demonstrated more precise alignment in the operated cases compared to conventional methods.

Conclusions:

  • The applied PSI technique is practicable and reliable, offering advantages in precise surgical planning.
  • While alignment results show promise, literature remains inconsistent, and soft tissue balancing requires further integration.
  • PSI technology is in its early developmental stages, with potential for future advancements.
