Could a posterior cruciate ligament (pcl) heal itself over time?

Usually not. Pcl injuries, if complete, have zero healing potential. In partial injuries (sprains) depending on your age and other factors healing is possible.
Yes. The majority of people with PCL tears do not have surgery. There are three grades of PCL tears 1, 2, 3. The general rule is that surgery can improve your grade by one notch. Thus if you are a grade 1 or 2, then surgery probably not needed. If you are not super active and do not have symptoms then surgery not needed. Good rehab focusing on quad strength will go a long way in this injury.

Related Questions

What could cause posterior cruciate ligament (pcl) injury?

Force! The PCL is probably the strongest ligament in the knee. It requires a significant amount of force or energy to cause it to tear. Pcl tears are far less common than anterior cruciate ligament (acl) tears.
Accidents and falls. Pcl injuries are typically caused by knee dislocations, car accidents when the knee hits a dashboard, and falls directly onto the bent knee. Anything that would case the leg (tibia) to move backwards from a directly blow could cause a PCL injury.

How can you prevent posterior cruciate ligament (pcl) injury?

You can't :- (Tears of the PCL will occur if a significant amount of energy is placed across the knee and in the right direction. Like if your knee hits the dashboard in car accident. That will push your shin backwards and potentially tear your pcl. Pcl tears can not be prevented.
Strong knee. Pcl injuries are somewhat rare and they usually occur by trauma such as car accidents and falls. Thus being safe is good prevention. Having very strong knee musculature and quads can help prevent PCL injury as well. Other than that it is not like the acl injury where there is a high rate of noncontact or pivoting causes of injury.

What are the common symptoms of posterior cruciate ligament (pcl) injuries?

Varies, usually none. Symptoms of a PCL rupture can vary. It may be associated with pain, swelling and a feeling of unsteadiness, but more often than not they may have no noticeable symptoms. Some report a feeling of unsteadyness or insecurity, others pain around the knee cap. Some report pain when running, especially slowing down/stopping, going up/down stairs or ramps, or squatting/kneeling.
Pain instability. Acute injuries will cause swelling of the knee and possible bruising behind the knee. Once it has settled down the main symptoms are instability of the knee or feeling like it will give out.

What is the definition or description of: posterior cruciate ligament?

Main knee stabilizer. The posterior cruciate ligament (pcl) is one of the main central ligaments within the knee that originates on the femur and inserts on the back of the tibia. The PCL prevents the tibia from displacing posteriorly.

How serious is a posterior cruciate ligament tear?

It serious. While a posterior cruciate ligament injury generally causes less pain, disability and knee instability than does an acl tear, it can still sideline you for several weeks or months.
PCL tear. An isolated PCL tear depending on degree can allow a person to function fairly well. A high grade or complete PCL may hasten patello-femoral arthritis. Often time a PCL tear is associated with posterolateral (pl) or posteromedial (pm) instability which warrants PCL reconstruction with pl or pm reconstruction.

Is surgery the best option for a torn posterior cruciate ligament?

Not Necessarily. This is a hard question to answer without more information. The answer depends on the left of physical activity. If you participate in sports, or any activities that require you to shift the direction you are moving in, very quickly then surgery is the best option. For normal activities such as walking and even occasional running PCL is not necessary. At best you might need a brace for running.
It depends. This depends on the degree of the tear, associated injuries, and the type of activity that you desire to return to. Generally, partial and low-grade isolated PCL injuries can be rehabbed and braced. High-grade or complete PCL injuries or lower-grade injuries which result in persistent instability may be better treated with surgical reconstruction. Talk to your orthopedist regarding your situation.
Not Necessarily. Often a PCL injury can be treated with bracing and physical therapy. It depends upon other pathology within your knee, and your functional requirements.

Please explain what happens with a posterior cruciate ligament tear?

Instability. The posterior cruciate ligament (pcl) is the ligament that keeps the tibia (shin bone) in line with the femur (thigh bone), and keeps it from dropping back behind. When it tears, the body tries to heal the tear but in a looser position. Sometimes this is loose enough to cause instability (where the knee sags back and is unable to maintain a normal position. This can cause other tears or disability.
