What Is Osgood-Schlatters?

Osgood-Schlatters is the disease of the tendon from the kneecap ( called the patella tendon ) that is connected to the shinbone ( called the tibia ), gets irritated when doing lots of physical activity and causes an inflammation.

The Body Systems Involved...

The systems involved are the muscular and skeletal. This disease is in the tendon but it also affects your bones.

How The Body System Works Normally And Differently With This Disease

Normally: The tendon from the kneecap ( patella ) is not inflamed, red, and swollen when doing physical activity.

Differently: The tendon from the kneecap ( patella ) is red, swollen during physical activity and that's whats causes this disease (inflammation).

Note: The role of the tendon is that it attaches the bottom of the kneecap to the top of the shinbone.

Target Population

  • Kids who play sports get this 20% more often then kids who don't
  • This disease can also run in the family; if a child has it it is 30% more likely that the sibling will to
  • Both girls and boys affected
  • Boys are affected between ages 13-15
  • Girls are affected between ages 10-11

How Does This Condition Arise?

This condition can arise from growing to fast. It can also arise from repetitive movement.

How Is This Condition Diagnosed?

This condition is diagnosed by having a bump or swollen area below the kneecap. Also your growth plates can be soft and weak. Limping after physical activity can be a very strong sign of this disease.

What Are The Signs And Symptoms Of This Disease?

The signs and symptoms of this disease are that your muscles and tendons can be tight, their will mostly likely be a bump/swollen area below the kneecap, your growth plates can be soft and weak, limping after physical activity, and when your doing activity the pain can feel worse.

What Can You Do To Treat This Disease?

To treat this disease the best thing you can do is take a break from physical activity. There are many other ways to though. My favorite is called R.I.C.E. It stands for, R rest from all physical activity, I Ice the knee, C compress the area, and E elevate the knee.


Stretching is a great way to help get rid of this disease and release some of the pain in your knees. One great stretch to do is lie face down and pull your foot gently toward you're buttock with your hand.


You can not die from this disease, but it does last a few years. For girls it is proven to last between ages 10-11. For boys this disease is proven to last between ages 13-15.


I know several people with this disease. Two of my friends and myself. It’s a very painful experience but the hardest part was taking a break for sports. I had to rest during the summer for about a month and do physical therapy for three months. I should have rested longer because now my knees still hurt from it. If I had rested and done stretches then the pain would be all gone, but now it will last longer. I chose this topic because I had a personal connection and I knew that some of my peers have it. Also it is a very interesting topic with many details that I wanted to know.
