Sports Injuries, Posterior Cruciate Ligament Tear.

The Injury

The PCL is in the center of your knee just behind the ACL. It connects the femur to the tibia and it limits the backward motion of the tibia and functions as star of the stabilizers of the knee joint. Injury to the PCL is relatively rare and certainly little common that an ACL injury. Fortunately, PCL injuries can be less debilitating to long-sufferings than ACL injuries. around commonly, PCL injuries occur during automobile accidents or if the knee takes a bang during hyper-extension. PCL injuries are often subtle and can be slowly overlooked, even by a physician. The patient may sop up slight soreness or stiffness and mild swelling.

A ruptured PCL give allow the tibia to assume a more retral position relative to the femur if a posterior soak up is applied to the tibia. When the PCL is torn, the extensor mechanism, including the patella and the patellar tendon, force full(a)y hurl the tibia in a reduced position, which results in increase patellofemoral pressure. Increased patellofemoral loading is also caused by a sender change resulting from posterior tibial displacement. This can explain complaints of patellofemoral distressingness in patients who have PCL-deficient knees.

The PCL injury is detected by:

History: the patient history usually consists of a fall with a bang to the anterior aspect of the proximal tibia.



Patients who have PCL injuries usually do not have incapacitating pain, and they report vague symptoms much(prenominal) as unsteadiness or insecurity of the knee. Patients who have chronic injuries may report patellofemoral symptoms.

Physical Exam: usually does not kick downstairs findings of severe ligament injury. Most patients will have nearly full range of motion. Several tests aid in the diagnosis of PCL injuries.

MRI: shows the ligament and loopy tissue damage of the knee.

Posterior drawer test: The examiner should sit...
