Hello and welcome to the Zero to Finals podcast.

My name is Tom and in this episode I'm going to be going through Osgood Schlatter's disease.

And you can find written notes on this topic at zero definals.com slash Osgood Schlatters

or in the orthopaedic section of the zero to finals surgery book so let's get

straight into it oscudslatter disease is caused by inflammation at the tibial tuberosity where the

patella ligament or the patella tendon inserts.

It's a common cause of anterior knee pain in adolescence.

Osgood Schlatter disease typically occurs in patients aged 10 to 15 years old and is more common in

males.

Osgood Schlatter disease is usually unilateral,

affecting only one knee, but it can be bilateral.

Let's talk about the pathophysiology.

The betelar ligament or the betelat tendon inserts into the tibial tuberosity.

This is a small lump that you can feel just below the knee cap at the top of the lower leg.

In patients with Osgood Schlatter disease,

multiple minor evulsion fractures occur where the patella ligament pulls away tiny pieces of the bone.

This leads to growth of the tibial tuberosity, causing a visible lump

below the knee. Initially, this lump is tender due to active inflammation in the area. As the bone

heals and the inflammation settles, the lump becomes hard and non-tender. A hard, non-tender lump is then

permanently present at the tibial tuberosity. Let's talk about the presentation. Osgood-Shlatter

disease presents with a gradual onset of symptoms. And these symptoms are a visible or palpable, hard and tender lump at the tibial tuberosity,

pain in the anterior aspect of the knee, and the pain is exacerbated by physical activity,
