YOA has new COVID-19 protocols to protect our patients, guests, staff, doctors and communities. We are now offering Virtual Care.

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.

If you have a cast, click here for a downloadable PDF with directions for how to take proper care of it.

If you have questions about a knee replacement and would like to learn more about what to expect leading up to, during and after the joint replacement surgery, visit this link.

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.
