What happens when a kneecap dislocates

Knee dislocation can be caused by a sudden blow, such as taking a hard hit playing a contact sport like football or hockey, or by a chronic condition, such as a stretched ligament. Some people have a particular knee anatomy that makes it more common. In those cases, a dislocation could be caused by something as simple as normal walking or standing up from a chair. With chronic dislocation, it may feel as though your knee is buckling or giving way. There’s often no pattern or regular causes of the dislocations.
