Knee fat pad hurt
Hoffa syndrome refers to what can happen if the kneecap recieves a direct blow.
Underneath the patella (kneecap) and the tendon connecting it to the lower leg is a fat pad. It can get pinched between the patella and the thigh bone. This can be very painful. Usually it gets better with rest, ice/heat and time. At times the fat pad can be so injured that surgery is needed.
