Torn Lateral Collateral Ligament, Anterior View

Description

Centered on the anterior knee, the distal femur overlies the proximal tibia with the patella seated anteriorly in the trochlear groove, while the tibial plateau and menisci form the articular interface below. Laterally, the fibular head and neck sit inferior and slightly posterior to the lateral tibial condyle, marking the distal attachment of the lateral collateral ligament (fibular collateral ligament) as it courses from the lateral femoral epicondyle. A discrete fiber discontinuity near the fibular head defines the tear, with the ligament ends separated along the lateral joint line. Cartilage caps the femoral condyles and tibial plateau, and the anterior soft tissue envelope frames the injury. Varus stress injuries rarely isolate the LCL, so a clear depiction of a distal LCL tear helps teach how lateral gapping relates to posterolateral corner involvement and why you should scrutinize adjacent stabilizers even when the cruciate ligaments are not in view from this anterior perspective. The fibular head attachment matters surgically because fixation, repair, or reconstruction tunnels are planned in close proximity to the common fibular (peroneal) nerve as it wraps around the fibular neck. Small space. Large consequences. Orthopaedic and sports medicine educators can pair this illustration with clinical exam teaching (varus stress testing at 0 and 30 degrees, dial test context) and with MRI correlation when discussing grading and management of lateral collateral ligament tears. It also fits operative technique chapters covering fibular-based reconstructions, lateral incision planning, and protection of the peroneal nerve during exposure around the fibular head.
