Overview

Cross-sectional analysis found no significant link between femoral component rotation and patient-reported outcomes in functionally aligned total knee arthroplasty.

Key Points

  • Significant improvements in patient-reported outcomes were observed at one year postoperatively.
  • No notable correlation was found between femoral component rotation and the Knee injury and Osteoarthritis Outcome Score-12.
  • A weak negative correlation between external femoral component rotation and the EuroQol 5-Dimension-5-Level score was noted.
  • The absence of significant differences suggests flexible femoral component rotation is acceptable in functionally aligned total knee arthroplasty.
