Knee & Leg

KneeThe knee is the largest joint in the body and is vital to its motion. Because we use our knees so much, they are especially vulnerable to injury. And because it is comprised of so many parts, many things with the knee can go wrong.

More information about the knee and leg is available from the Academy of Orthopaedic Surgeons, of which YOA is a member. Visit the Academy links below to learn more.
