Articular capsule of the knee joint are remnants of three embryonic septal divisions of the knee space called synovial plicae: Articular capsule of the knee joint The articular capsule of the knee joint (commonly referred to as capsular ligament) is wide and lax; thin in front and at the side; and contains the patella ("knee cap"), ligaments, menisci, and bursae. The capsule consists of a synovial and a fibrous membrane separated by fatty deposits anteriorly and posteriorly. Anteriorly, the reflection of the synovial membrane lies on the femur; located at some distance from the cartilage because of the presence of the suprapatellar bursa. Above, the reflection
Tibia lateral side of the tibia. The part of the ankle joint known as the talocrural joint, is a synovial hinge joint that connects the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus. The articulation between the tibia and the talus bears more weight than between the smaller fibula and the talus. The tibia is ossified from three centers; a primary center for the diaphysis (shaft) and a secondary center for each epiphysis (extremity). Ossification begins in the center of the body, about the seventh week of fetal life, and gradually
