Routine patellar resurfacing in total knee arthroplasty (TKA) shows similar anterior knee pain rates compared to unresurfaced patellas. However, resurfacing significantly reduces reoperation rates when performed with proper surgical technique.

Area of Science:

  • Orthopedic surgery
  • Biomedical engineering

Background:

  • Anterior knee pain is a common concern following total knee arthroplasty (TKA).
  • The decision to resurface the patella during TKA remains a topic of clinical debate.
  • Existing literature presents conflicting data regarding the efficacy of patellar resurfacing.

Purpose of the Study:

  • To evaluate the impact of routine patellar resurfacing on anterior knee pain after TKA.
  • To compare complication and reoperation rates between resurfaced and unresurfaced patellas in TKA.
  • To determine the optimal surgical approach for managing the patella during TKA.

Main Methods:

  • Literature review of studies comparing patellar resurfacing versus non-resurfacing in TKA.
  • Analysis of complication rates, specifically reoperation rates for patellar issues.

  • Assessment of anterior knee pain incidence in both surgical groups.

    • Main Results:

    • The incidence of anterior knee pain is comparable regardless of whether the patella is resurfaced or not.
    • Patients with an unresurfaced patella have a higher reoperation rate (approximately 10%).
    • Routine patellar resurfacing, when executed with correct surgical technique, results in negligible patellar complications.

    Conclusions:

    • Routine patellar resurfacing is associated with significantly lower reoperation rates compared to leaving the native patella.
    • Surgical technique is the most critical factor in minimizing patellar complications after TKA.
    • Properly performed routine patellar resurfacing yields the best overall outcomes in TKA.
