Tibia tibia is most contracted in the lower third and the distal extremity is smaller than the proximal. The proximal or upper extremity of the tibia is expanded in the transverse plane with a medial and lateral condyle, which are both flattened in the horizontal plane. The medial condyle is the larger of the two and is better supported over the shaft. The upper surfaces of the condyles articulate with the femur to form the tibiofemoral joint, the weightbearing part of the kneejoint. The medial and lateral condyle are separated by the intercondylar area, where the cruciate ligaments and the menisci
Superior tibiofibular joint Superior tibiofibular joint The proximal tibiofibular articulation (also called superior tibiofibular joint) is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. The contiguous surfaces of the bones present flat, oval facets covered with cartilage and connected together by an articular capsule and by anterior and posterior ligaments. When the term "tibiofibular articulation" is used without a modifier, it refers to the proximal, not the distal (i.e., inferior) tibiofibular articulation. Injuries to the proximal tibiofibular joint are uncommon and usually associated with other injuries to the lower leg. Dislocations can be classified into
