How to Tap a Kneecap

The American Academy of Family Physicians estimates that knee stress is the cause of one-third of all musculoskeletal problems in the country. Proper diagnosis of knee problems requires an understanding of the different parts of the knee and how they work together. Doctors tap your kneecap to test your knee's reflexes which helps them to make a diagnosis. Tapping your knee cap can be done at home, but diagnosis will be difficult without medical expertise.
