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.
There are two menisci in the knee. They sit between the thigh bone and the shin bone. While the ends of the thigh bone and the shin bone have a thin covering of soft hyaline cartilage, the menisci are made of tough fibrocartilage and conform to the surfaces of the bones they rest on. One meniscus rests on the medial tibial plateau; this is the ...
Injuries to the PLC often occur in combination with other ligamentous injuries to the knee; most commonly the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). [2] As with any injury , an understanding of the anatomy and functional interactions of the posterolateral corner is important to diagnosing and treating the injury.
Then, the new ligament is attached to the bone of the thigh and lower leg with screws to hold it in place. [19] Surgery to repair the posterior cruciate ligament is controversial due to its placement and technical difficulty. [20] It is possible for the PCL to heal on its own without surgery when it is a Grade I or Grade II injury.
A soft tissue injury is the damage of muscles, ligaments and tendons throughout the body. Common soft tissue injuries usually occur from a sprain, strain, a one-off blow resulting in a contusion or overuse of a particular part of the body. Soft tissue injuries can result in pain, swelling, bruising and loss of function. [1]
MRI can also show associated bone bruises on the lateral side of the knee, which one study shows, happen in almost half of medial knee injuries. [ 19 ] Knee MRIs should be avoided for knee pain without mechanical symptoms or effusion, and upon non-successful results from a functional rehabilitation program.
X-ray and MRI after luxation of the patella. There is a fragment and bone bruise at the medial surface of the patella and in the corresponding surface of the lateral condyle of the femur. The medial retinaculum of the patella is disrupted. Two types of treatment options are typically available: Surgery
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
