Our knee is made up of the thighbone (femur), which has a bottom end made up of two rounded knobs (condyles), setting on the comparatively flat top end of the shinbone (tibia). The kneecap is a small, rounded bone that sits in the vertical groove between the two condyles and gives strength to the joint.
As the knee bends and straightens, the kneecap slides up and down in the groove. A tendon attaches the kneecap to the thigh muscles above, and a ligament connects it to the shinbone below. The kneecap acts like a pulley, increasing the power of the muscles attached to it.
Knee pain can be caused by a sudden injury, an overuse weariness/ injury, or by an underlying condition of the body , such as arthritis. Treatment can vary depending on the cause. Different symptoms of knee injury can include pain, swelling, and stiffness of joint etc.
