Overview

Retrospective analysis shows the link between tibial component rotation and patient outcomes in TKA, suggesting alignment matters.

Key Points

  • Externally rotated tibial components correlate with improved walking and standing scores at two years.
  • Patients exhibited an average external rotation of 6.2 degrees postoperatively, influencing clinical outcomes.
  • The study employed a retrospective cross-sectional design, evaluating correlations using CT and outcome scores.
  • Modified tibial alignment can enhance patient-reported outcomes, highlighting the need for precise surgical techniques.
