What is Osgood Schlatter Disease?

To understand our Osgood-Schlatter Disease (OSD) training program, you first need to understand the problem.

What causes Osgood Schlatter Disease?

Put simply, Osgood Schlatters Disease occurs when the thigh bone (femur) grows too fast for the longest quad muscle (rectus femoris) to keep up. This means with every step the athlete takes the muscle is pulling at its attachment site below the knee cap (the tibial tuberosity).

Below is an isolated picture of the femur and the rec fem as well as a closer view of the knee. The shiny thing in the middle is the prepatellar bursa which sits in front of the kneecap itself (the patellar). As you can see the tendon goes from the quad above and then down to its attachment site at the top of the shin bone (tibia).


Looking at this it is pretty easy to understand that a tight quad (rec fem) that can’t keep up with a rapidly growing femur is going to cause drama at the tibial tuberosity. It’s as though the bones are literally tearing the tendon off its attachment site at the top of the shin.

As if that isn’t bad enough, this is also compounded by the fact that the attachment sights are not fully bonded, as they need to stay like semi-set glue to allow for further growth and skeletal maturation. Add in tall kids with no glutes, terrible running techniquer and a 48-week season on a hard surface and it’s easy to see plenty of Osgood drama in basketball, tennis and netball.

What does osgood schlatter disease feel like?

The exact feeling can vary between people, but typically

So that’s it: Osgood occurs when the bones grow too fast for tight quad muscles to keep up resulting in soft developing attachment points getting angry. The good news is you can take action and strengthen your way out of pain, our seven week training program provides the solution to help.
