Health Information For Teens
The knee is a joint that joins the thigh bone (femur) to the top of the shin bone (tibia). It is made up of bones,
, and tendons. These parts work together to make the legs bend, straighten, and swivel. A knee injury can damage one or more parts of the knee.
Teens may injure a knee in a fall or accident. Active and athletic teens might have overuse knee injuries. These happen when someone trains too much or makes repetitive motions involving the knee.
Common knee injuries in teens include:

The signs and symptoms of a knee injury depend on the cause. Most knee injuries cause pain. A knee injury may also lead to the knee feeling weak, “giving way,” or “locking.” Someone with a knee injury might not be able to fully bend or straighten the knee. The injured knee may be swollen or bruised.

If your knee hurts, it is important to know why. Go to a health care provider to find out what’s causing the pain and to get treatment.
Patellofemoral pain syndrome (or runner’s knee) is the most common overuse injury among runners, but it can also happen to other athletes who do activities that require a lot of knee bending.
Jumper’s knee is an overuse injury that happens when frequent jumping, running, and changing direction damages the patellar tendon.
ACL injuries can happen in active and athletic kids when excessive pressure is put on the knee joint, resulting in a torn ligament.
If you tore your ACL, you might need this surgery to fix it. Find out what’s involved.
MCL injuries happen when excessive pressure is put on the knee joint, causing a torn ligament.
The key to healing meniscus tears is not to get back into play too quickly. Find out what meniscus tears are and how to treat them.
Overuse (or repetitive stress) injuries happen when too much stress is placed on a part of the body, causing problems like swelling, pain, muscle strain, and tissue damage.
Osgood-Schlatter disease (OSD) is an overuse injury that can cause knee pain in teens, especially during growth spurts. Learn more.
Playing hard doesn’t have to mean getting hurt. The best way to ensure a long and injury-free athletic career is to play it safe from the start. Find out how.
Our bones, muscles, and joints form our musculoskeletal system and enable us to do everyday physical activities.
If the tendon just above your heel becomes swollen or irritated due to overuse, it can lead to a painful condition called Achilles tendonitis. Find out how to treat it – and prevent it.
Blount disease is a growth disorder that affects the bones of the lower leg. It causes bowing of the leg below the knee, which gets worse if it’s not treated.
