Area of Science:

  • Orthopedic Surgery
  • Biomechanical Engineering
  • Anatomy

Background:

  • Patellar resurfacing is a key component of total knee arthroplasty (TKA).
  • Current patellar resection techniques can lead to variability.
  • Standardized anatomical landmarks are needed for consistent resection.

Purpose of the Study:

  • To geometrically assess anatomically based patellar resection criteria for TKA.
  • To establish a simple, consistent, and reliable method for patellar resection.
  • To evaluate the geometric uniformity of resected patellae.

Main Methods:

  • Thirty-six patellae were used for geometric assessment.
  • Resection plane defined in the coronal plane using specific anatomical landmarks.
  • Depth of resection determined by ligament insertion points.

  • Geometrical characterization using a 2D Cartesian coordinate system.

    • Main Results:

    • Anatomically based resection yielded a simple, consistent, and reliable method.
    • Remaining patellar thickness was 65.6+/-5.3% of original.
    • Resected surface width-to-height ratio was approximately 1:1.
    • Resected portion thickness-to-diameter ratio was approximately 1:5.

    Conclusions:

    • Anatomically based patellar resection provides a uniform geometric outcome.
    • This method may reduce surgical variations in patellar resurfacing for TKA.
    • Applicable for dome-shaped prostheses in total knee arthroplasty.
