About this episode:
Accurate femoral component rotation is vital for a successful Total Knee Arthroplasty (TKA). In this Arthroplasty Focus video abstract, the authors investigate which anatomical reference—the Transepicondylar Axis (TEA) or the Posterior Condylar Axis (PCA)—offers better consistency between surgeons when using a robotic system.

Key Findings:
✅ Superior Consistency: The PCA was identified with significantly higher inter-surgeon reliability (ICC 0.943) compared to the TEA (ICC 0.761).
✅ Risk of Error: Over 26% of TEA measurements showed a difference greater than 2° between surgeons, compared to only 5.4% for PCA.
✅ Clinical Strategy: The study suggests that anatomical variations (like flat lateral condyles) make TEA harder to pinpoint, recommending a cross-referencing strategy for optimal accuracy.
