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 [5] then stretches, at a posterior and lateral angle, toward the posterior of the tibia just below its articular surface.
Even for other upper extremity joints – elbow and wrist, backward movement results in extension. The knee, ankle, and wrist are exceptions, where the distal end has to move in the anterior direction for it to be called extension. [13] [page needed] For the toes, flexion is curling them downward whereas extension is uncurling them or raising them.
Peroneal nerve is most commonly interrupted at the knee and possibly at the joint of hip and ankle. Most studies reported that about 30% of peroneal nerve palsy is followed from knee dislocations. [1] Peroneal nerve injury occurs when the knee is exposed to various stress. It occurs when the posterolateral corner structure of knee is injured.
Repetitive shoulder movements, overhead, swinging, throwing or circling movement can cause musculoskeletal injury. [16] Some cases can result in spinal cord damage at the C3-C5 levels, producing a myelopathy which can dramatically compromise overall movements in arm and legs as well as other fine motor functions .

Pronation at the forearm is a rotational movement at the radioulnar joint, or of the foot at the subtalar and talocalcaneonavicular joints. [ 11 ] [ 12 ] For the forearm, when standing in the anatomical position , pronation will move the palm of the hand from an anterior-facing position to a posterior-facing position without an associated ...
Patellofemoral pain syndrome is associated with pain in the knee and around the patella (kneecap). It is sometimes referred to as runner's knee, but this term is also used for other overuse injuries that involve knee pain. It can be caused by a single incident but is often the result of overuse or a sudden increase in physical activity.
A computertomographie of a 13-year-old child who was diaognised by "Trevor disease", which is an additional bone growth on the knee or ankle. Ankle problems occur frequently, having symptoms of pain or discomfort in the ankles. [1] [2] Mild ankle pain can often be cured by home treatments, although these may be slow to take effect.
Nearly 41% of knee dislocations have an associated fracture, with the majority of these fractures in one of the legs. [44] Nerve injury occurs in about 15.3% of knee dislocations, while major artery injury occurs in 7.8% of knee dislocations. [44] More than half (53.5%) of knee dislocations have an associated torn meniscus. [44]
