Patellar resurfacing in total knee replacement is debated. This study found the inset technique to be a simple and safe method for patellar resurfacing, with minimal changes in patellar thickness.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Arthroplasty Research

Background:

  • Patellar management in total knee arthroplasty (TKA) remains a controversial topic.
  • The decision to resurface the patella during primary TKA is not universally agreed upon.
  • Existing literature presents varied outcomes and techniques for patellar resurfacing.

Purpose of the Study:

  • To evaluate the safety and efficacy of the inset technique for routine patellar resurfacing in primary total knee arthroplasty.
  • To assess the impact of the inset technique on patellar thickness.
  • To determine the complication rate associated with this specific patellar resurfacing method.

Main Methods:

  • A consecutive series of 220 primary total knee replacements performed by a single surgeon were reviewed.

Athymic Rat Model for Evaluation of Engineered Anterior Cruciate Ligament Grafts

  • The patella was routinely resurfaced using the inset technique in all cases.
  • Patellar thickness was measured pre- and post-operatively to assess changes.

    • Main Results:

    • Patellar thickness was unchanged in 54.5% of cases.
    • In 97.2% of cases, patellar thickness was altered by no more than 2 mm from the original.
    • No significant complications related to patellar resurfacing were reported.

    Conclusions:

    • The inset technique for patellar resurfacing in total knee replacement is a straightforward and safe procedure.
    • This technique demonstrates minimal alteration of patellar thickness, suggesting good preservation of native anatomy.
    • Routine patellar resurfacing using the inset technique can be considered a viable option in primary TKA.
