Can you dislocate your knee without tearing ligaments?

As is the case with all other joints, ligamentous disruption or tearing occurs to allow the joint to dislocate. In the case of patellar dislocation, the ligaments on the inside of the knee are the most commonly injured as the kneecap slides laterally. While tearing of these ligaments is unfortunate, they do have the potential to heal.

Is it normal to have a dislocated knee? Knee dislocations are severe injuries with obvious deformities. About half the time, the bones move back into position by themselves and the joint looks normal. However, knee dislocations often occur along with fractures of the femur or tibia. There is also a high rate of artery, nerve, tendon and muscle damage.

How is a dislocated knee different from a broken kneecap? A dislocated knee is different than a dislocated kneecap. That occurs when the kneecap bone slips out of place.

Dislocation can damage several important ligaments, blood vessels, and nerves.

What kind of ligament is torn when knee comes out of joint? When the kneecap comes out of joint the first time, ligaments that were holding the kneecap in position are torn. The most important torn structure is called the medial patellofemoral ligament, or MPFL. This ligament secures the patella to the inside (medial) part of the knee.
