A 37-year-old member asked:

what diffuses the tear of the anterior cruciate ligament with posterior displacement within the intercondylar?

Nothing: There is nothing that would "diffuse" a tear of the anterior cruciate ligament (acl). Acl is one of only few ligaments in our body that is entirely intra-articular which means it is not within soft tissues but is sitting inside the joint space with some surrounding joint fluid. This atmosphere makes it impossible for the ACL to heal (which I am assuming what you meant by diffuse).

A 25-year-old member asked:

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.

What are some good exercises that someone can do at home for a torn acl?

Knee motion & quads: Most ACL tears may require reconstruction. Early home therapy is routinely geared toward preparing your lower extremity for surgery. Quadriceps exercises are excellent. Simple repeated bending and straightening your knee once tolerable also helps decrease swelling, keeps the joint from getting stiff, and keeps the cartilage or joint lining healthy. The default position at rest is full extension.

With expert guidance: Appropriate treatment of a torn ligament depends a variety of factors including which ligament is injured, how badly it is injured, what other structures are injured, what the functional demands of the patient are, how much instability the injury causes, how old the patient is, what other medical problems the patient has, etc., and is best determined in consultation with qualified physician.

A 37-year-old member asked:

Can you tell me the difference between a damaged tendon and a damaged ligament?

3 doctor answers10 doctors weighed in
Dr. Aileen Shieu
Hand Surgery 20 years experience
Yes: The tendons move your fingers and wrists. If it is damaged, you may lose the ability to bend or straighten the affected part. Ligaments support your joints, holding bones together. If that is damaged, you may have swelling to the region and instability to the joint. This means that it may hurt when you move the joint, or that it will move improperly.
