Fibular Articular Facet Of The Tibia, Posterior View

Description

Fibular articular facet on the posterior aspect of the lateral tibial condyle occupies the center of this posterior knee view, its shallow, slightly grooved surface oriented inferolaterally toward the head of the fibula. Superior to the facet, the posterior margin of the lateral tibial condyle forms a rounded lip, while medially the posterior intercondylar area and intercondylar eminence lie closer to the midline of the proximal tibia. Inferiorly, the proximal tibial metaphysis continues into the posterior tibial surface, creating a broad bony backdrop that frames the proximal tibiofibular joint line. This bony contact surface matters because the proximal tibiofibular joint often becomes symptomatic in athletes and after knee trauma, and subtle malalignment or instability can present as posterolateral knee pain that is easy to confuse with lateral meniscal or posterolateral corner injury. A posterior perspective is also where the clinician mentally maps adjacent high-risk structures: the fibular head sits lateral to this facet, and the common fibular (peroneal) nerve then courses around the fibular neck, a relationship that explains neuropraxia after proximal tibiofibular dislocation or aggressive lateral exposure. Joint injections, surgical fixation of proximal fibular fractures, and approaches that work near the posterior proximal tibia all benefit from a precise understanding of where this facet sits relative to the condylar contours and the midline intercondylar landmarks. Small surface, big consequences. Use this illustration for gross anatomy teaching of the proximal tibia, orthopaedic and sports medicine texts discussing proximal tibiofibular instability, and surgical education on posterolateral knee anatomy where bony landmarks guide safe dissection.
