See also: Dislocation
Causes:
A dislocated kneecap most often occurs in women. It is usually a result of sudden direction changes while running. This puts the knee under stress.
Dislocation may also occur as a direct result of injury. When it is dislocated, the kneecap may slip sideways and around to the outside of the knee.
