A fracture to the patella or knee cap can commonly come from direct impact from a fall or vehicle accident. Also, strong muscles in the thigh suddenly contracting can cause the knee cap to crack.
Using X-ray imaging is the prevalent method. Together with a doctor’s examination and check on injury history, these can identify the nature and severity of the fracture.
