Knee injuries are often a result of a twisting or a direct impact injury to your leg. The severity of the injury can vary but loss of bending in the knee is common after an injury. An inability to straighten and bend your knee is a sign you have been injured badly.

Here is a look at the top reasons why you are unable to straighten your knee after an injury.

Swelling

Swelling is common after injuries that cause bleeding, inflammation and pain, making it too painful to straighten the knee.

Tendon Injuries

Injuries to the quadriceps or patella tendon do not allow you to straighten the knee and also cause significant weakness. Such injuries are more common in professional sports.

Meniscus Tear

A tear in which the torn piece of meniscus flips into the center of the knee joint, can lock your knee and prevent it from straightening.

ACL Tear

ACL tear do not cause the knee to be locked but it hurts too much to straighten it. Within a few days, the swelling will reduce and you may be able to straighten your knee. But sometimes ACL tear is accompanied by a meniscus tear. In such cases, it will be hard to straighten the knee and you should see an orthopedic surgeon.
