Kneecap Dislocations
Diagnosis of a Dislocated Kneecap
A doctor's evaluation X-rays to check for fractures A dislocated kneecap may slide back into place on its own before people can see a doctor. However, people should still see a doctor so that the doctor can check for fractures that may have occurred during the injury. If a kneecap moves out of place, people should see a doctor regardless of whether the kneecap slides back in place on its own. Doctors can diagnose a dislocated kneecap when they examine the knee. If the kneecap has already slid back in place, they may suspect that it was dislocated because they detect blood within the joint and the joint is tender. Doctors take x-rays from several angles to check for fractures.
