Lateral Collateral Ligament, Posterior View

Description

Posteriorly, the fibular (lateral) collateral ligament (ligamentum collaterale fibulare) is shown as a cordlike band running inferolaterally from the lateral epicondyle of the distal femur to the lateral surface of the fibular head. The ligament sits lateral to the posterolateral corner structures and remains extracapsular, separated from the lateral meniscus by the tendon of the popliteus as it courses from the posterior tibia toward the femoral condyle. Adjacent osseous landmarks include the lateral femoral condyle superiorly and the proximal tibia and fibula inferiorly, with the fibula positioned posterolateral to the tibia in anatomical alignment. Clear spatial relationships. Clinical relevance centers on lateral knee stability against varus stress and posterolateral rotatory instability, where injury to the LCL often travels with damage to the biceps femoris tendon, popliteofibular ligament, or the common fibular (peroneal) nerve as it wraps around the fibular neck. A posterior perspective is the one surgeons want when planning or reviewing a posterolateral corner reconstruction, and it also mirrors what you assess during stress examination and when reading MRI for discontinuity, edema, or avulsion at the fibular head. The included knee arthroplasty components add a practical layer, because lateral-sided pain or instability after total knee replacement can reflect soft-tissue imbalance or unrecognized lateral ligament insufficiency. Orthopedic and sports medicine curricula can use this artwork to teach the distinction between the fibular collateral ligament and the lateral capsular complex, and to orient learners to femoral and fibular attachment sites before cadaver lab or arthroscopy simulation. It also fits operative technique manuals, preoperative counseling materials, and journal figures discussing varus laxity, posterolateral corner injury patterns, or instability after knee arthroplasty.
