AL 129-1 a monkey, and decided to collect it. While he was writing it up, he noticed a few yards away a distal femur, the lower end of a thighbone. This was split between the condyles, or lumps making the knee joint. The other condyle lay next to it, and when he fitted them together and to the proximal tibia, the angle that the femur and tibia formed at the knee joint clearly showed that this was an upright walking hominid. This angular joint was in contrast to an ape, which has the femur and tibia forming a straight line. Tom Gray
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
