A Lateral View Of The Lateral Femoral Epicondyle

Description

Rotating through a lateral perspective of the distal femur, the animation centers on the lateral femoral epicondyle as it rises from the lateral surface of the lateral femoral condyle. The lateral supracondylar ridge tracks proximally along the lateral shaft, while the articular contour of the condyle curves inferiorly toward the tibiofemoral joint line. Just posterior and slightly inferior to the epicondyle, the popliteus groove (sulcus for the popliteus tendon) becomes apparent as a shallow channel on the lateral condyle. Bony relief is the point. Orthopedic teaching often blurs the distinction between the lateral epicondyle, the lateral collateral ligament attachment on the epicondylar region, and the popliteus tendon’s relationship to the condyle; this sequence separates them by showing how the groove sits posterior to the epicondylar prominence rather than on its apex. That spatial clarification matters in posterolateral corner injury patterns, where avulsion fragments and marrow edema can be misread on radiographs, CT, or MRI if the viewer does not have a firm 3D map. The progressive rotation also supports surgical orientation for a lateral approach to the knee, where palpable bony landmarks guide safe dissection planes before the soft tissues are even visible. Use it in lower limb anatomy labs, orthopedic residency lectures on knee ligament and posterolateral corner reconstruction, and as an atlas insert for MSK imaging chapters discussing distal femoral landmarks and the popliteus tendon sulcus on axial MR. It also fits preoperative patient education when explaining why pain localizes to the lateral femoral condyle region. Anatomical accuracy verified by SciePro's Medical Advisory Board.
