The medial condyle is larger than the lateral (outer) condyle due to more weight bearing caused by the centre of mass being medial to the knee. On the posterior surface of the condyle the linea aspera (a ridge with two lips: medial and lateral; running down the posterior shaft of the femur) turns into the medial and lateral supracondylar ridges ...
The bony congruity of the medial knee consists of the opposing surfaces of the medial femoral condyle and the medial tibial plateau. On the medial femoral condyle there are three bony landmarks that are important: the medial epicondyle, adductor tubercle, and gastrocnemius tubercle. The medial epicondyle is the most distal and anterior prominence.
The lower extremity of femur (or distal extremity) is the lower end of the femur (thigh bone) in human and other animals, closer to the knee. It is larger than the upper extremity of femur, is somewhat cuboid in form, but its transverse diameter is greater than its antero-posterior; it consists of two oblong eminences known as the lateral condyle and medial condyle.
The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...
In this medial view of the flexed knee, the lateral femoral condyle has been removed to reveal the structure of the PCL. Because the anterolateral bundle is stretched and the posteromedial bundle relaxed during flexion, excessive flexion in the form of hyperflexion causes tensile stress, shown in red, on the anterolateral bundle of the PCL that leads to PCL injury.
The PCL is located within the knee joint where it stabilizes the articulating bones, particularly the femur and the tibia, during movement.It originates from the lateral edge of the medial femoral condyle and the roof of the intercondyle notch [2] then stretches, at a posterior and lateral angle, toward the posterior of the tibia just below its articular surface.
Lateral head: lateral aspect of lateral condyle of femur Medial head: popliteal surface of femur; superior to medial condyle: Posterior surface of calcaneus via calcaneal tendon: Tibial nerve (S1, S2) Plantarflexes ankle when knee is extended; raises heel during walking; flexes leg at knee joint Plantaris
It is an abductor and a weak flexor, and also helps maintain the arch of the foot. Lateral to the abductor hallucis is the flexor hallucis brevis, which originates from the medial cuneiform bone and from the tendon of the tibialis posterior. The flexor hallucis has a medial and a lateral head inserted laterally to the abductor hallucis.
