Key Points

  • Surgeon handedness does not significantly affect overall functional outcomes after total knee arthroplasty, indicating consistency in results.
  • The tibial component placement was notably more precise on the dominant side, with fewer positioning outliers observed during procedures.
  • This observational analysis suggests that surgeon handedness is less critical compared to surgical technique and planning accuracy, which are vital for effective outcomes.
  • The study emphasizes the importance of technique over handedness in knee arthroplasty outcomes, highlighting reliable surgical practices.

Abstract

The overall radiological and functional outcomes after primary TKA were unaffected by the surgeon's handedness; however, the placement of the tibial component was significantly more precise on the dominant side with fewer outliers.
