Dorsal Cortex Line Is More Reliable Than Transepicondylar Axis For Rotation In Revision Total Knee Arthroplasty With Severe Bone Loss

Description

In this episode of AI Talks with Bone and Joint, hosts Simon and Amy delve into the study "Dorsal cortex line is more reliable than transepicondylar axis for rotation and revision total knee arthroplasty with severe bone loss," authored by M. Saltzman et al. The discussion highlights the significance of identifying reliable landmarks for femoral component rotation in complex knee arthroplasties, especially in cases involving severe bone loss where conventional methods may fall short. The hosts explore the study's findings, which suggest that the Dorsal Cortex Line (DCL) offers a more dependable alternative compared to the traditional surgical transepicondylar axis (sTEA). The DCL demonstrated robust reliability, achieving high scores in intra- and inter-rater consistency among experienced surgeons analyzing CT scans. However, they note the presence of measurement outliers, underlining the need for careful intraoperative assessments. The episode emphasizes the promising role of the DCL in surgical practice, particularly for revision procedures where accurate alignment is critical.
