Osgood-Schlatter

A painful lump just below the kneecap in teenagers, usually between thirteen and seventeen. The knee is where it hurts; the assessment looks at what is causing it.

What you notice

Symptomsand causes

If this sounds like your pain, there is a structural reason for it. The assessment is what finds it.

Common symptoms

  • A tender lump at the top of the shin bone, just below the kneecap
  • Pain at the front of the knee that is worse with running, jumping and stairs
  • Pain when kneeling
  • Often during a growth spurt, and more often in boys
  • Usually one knee, but it can be both

What causes it

At this age the top of the shin bone is still growing and is softer than the bone around it. The tendon from the kneecap attaches there. Where the shin is rotated — inwards or outwards — and the hip muscles tighten to compensate, a twist is created through the knee. The tendon then pulls on the growing area repeatedly, which inflames it and can pull it away from the bone, forming the lump. Bone and soft tissue growing at different rates is part of why it happens when it does.

How we diagnose it

The cause,not the sore spot

Osgood-Schlatter is diagnosed with the Najjarine Biomechanical Assessment, so treatment is prescribed against a finding rather than a symptom.

01

Assess

We assess the whole limb rather than only the knee, because the twist through the knee usually starts below it or above it.

02

Diagnose

We identify where the rotation is coming from — the shin, the hip, or the way the foot is loading — and explain what we found.

03

Treat

Treatment is prescribed against that finding, and staged around your teenager’s growth and sport.

Questions

Osgood-Schlatterquestions

The lump can remain after the pain settles. What the assessment addresses is the pulling that is causing it, and your podiatrist will explain what to expect.

Until they have been assessed, yes. Running and jumping keep pulling on the growing area below the kneecap. Once we know what is causing it, your podiatrist will tell you what they can return to and when.

Stretching the front of the thigh is often suggested for this condition. Where the tendon is already pulling on a growing area, our clinical approach is not to add more traction to it. Your podiatrist will explain what to do instead.

Because the shin rotates between the two. A twist that shows up as knee pain is often driven by how the foot is loading and how the hip is compensating, which is what the assessment measures.
