Lateral Femoral Epicondyle, Lateral View

Description

Lateral femoral epicondyle landmarks dominate the distal femur in lateral profile, with the roughened epicondylar prominence positioned superior and slightly posterior to the lateral femoral condyle’s articular surface. Inferior to the epicondyle, the convex lateral condyle curves toward the tibiofemoral joint line, while the nonarticular lateral surface transitions posteriorly toward the intercondylar region. Just distal and posterior to the epicondyle, the popliteus groove (sulcus for the popliteus tendon) is identifiable on the lateral condyle, separating the tendon’s track from the adjacent capsular attachments. Bony texture is explicit. For knee clinicians, the lateral femoral epicondyle is the femoral attachment site of the fibular (lateral) collateral ligament, a reference point when assessing posterolateral corner injury and planning anatomic LCL reconstruction tunnels. The popliteus groove matters in arthroscopy and open posterolateral approaches because the popliteus tendon enters the joint here, closely related to the lateral meniscus and capsule, and its position helps orient the surgeon when working near the lateral gutter and femoral condyle. A fixed lateral perspective makes the epicondyle-to-condyle relationship easier to teach than anterior or posterior projections, where the prominence can be visually crowded by the intercondylar notch and posterior condylar contours. Orthopaedic anatomy courses and sports medicine modules can pair this illustration with ligament and tendon overlays to explain varus instability patterns, Segond-type avulsion mechanisms, and graft placement geometry. It also fits operative technique manuals for lateral-sided knee reconstruction, arthroplasty landmark orientation, and radiology teaching files that correlate palpation points with CT or MRI bony morphology.
