Osgood-Schlatter Disease
Osgood-Schlatter disease is pain and swelling just below the kneecap, where the tendon attaches to a growth area on the shin bone. At Modern Physio we focus on understanding the root-cause of your problem & personalizing your treatment for lasting results.
Understanding Osgood-Schlatter Disease
Osgood-Schlatter disease is pain and swelling just below the kneecap, where the tendon attaches to a growth area on the shin bone. It occurs in growing children and adolescents, typically those playing a lot of sport, during a growth spurt when bones lengthen faster than muscles adapt. The name sounds alarming and the word "disease" is misleading — it is a self-limiting condition of growth rather than a disease process, and it settles once growth completes. That does not mean nothing should be done: sensible load management and strengthening let most young athletes keep playing while it runs its course, instead of stopping sport for months.
Common Symptoms
- Pain and tenderness just below the kneecap, over a bony bump on the shin
- A visible or palpable lump at that point
- Pain that worsens with running, jumping and stairs
- Pain that eases with rest and returns on resuming sport
- Swelling over the painful area
- Discomfort kneeling
- Often affecting both knees, though usually one more than the other
How Common Is It?
Osgood-Schlatter is one of the most common causes of knee pain in physically active adolescents, and typically occurs during the growth spurt years. Symptoms resolve as skeletal growth completes, though a painless bony bump often remains.
Causes & Risk Factors
- Rapid bone growth during an adolescent growth spurt
- Repetitive pull of the quadriceps tendon on the growth area
- High volumes of running and jumping sport
- A sudden increase in training load
- Tight quadriceps and hamstring muscles
- Relative weakness in the hip and thigh muscles
Our Diagnosis Process
- History of the pain, sport involved, and any recent increase in training
- Locating the tenderness precisely — its position over the growth area is characteristic
- Assessment of quadriceps and hamstring flexibility
- Assessment of hip and thigh strength and jump-landing mechanics
- Screening for other causes of adolescent knee pain, with referral where the picture does not fit
Our Treatment Approach
- Load management rather than complete rest: adjusting training volume so the knee settles while sport continues where possible
- Quadriceps and hamstring flexibility work
- Strengthening the hip and thigh muscles to reduce the pull on the growth area
- Improving jump and landing technique
- Ice after activity for symptom control
- A staged return to full training as symptoms settle
Recovery & Prevention Tips
- Adjust training volume rather than stopping entirely — complete rest tends to mean deconditioning and a harder return
- Stretch the quadriceps and hamstrings consistently, particularly through growth spurts
- Use a knee pad for kneeling if that is painful
- Expect symptoms to fluctuate with growth and training load
- Tell the coach; managing this well needs the training plan to change, not just the exercises

Frequently Asked Questions
Does my child have to stop playing sport?
Usually not entirely. Most young athletes manage with adjusted training volume, strengthening and flexibility work. Complete rest often makes the return harder, because the muscles deconditioned in the meantime.
Will the lump go away?
The bony bump often remains permanently, but it is usually painless once growth completes. Its presence afterwards is not a problem.
How long does it last?
It typically settles as skeletal growth finishes, which can mean months rather than weeks, with symptoms fluctuating in the meantime. Management is about keeping your child playing comfortably through that period.
Is it causing lasting damage?
It is a self-limiting condition of the growth area rather than a damaging process. Pain that is severe, present at rest or at night, or accompanied by systemic symptoms is a different picture and needs medical assessment.
Do knee straps help?
Some young athletes find a patellar strap reduces symptoms during activity. It is worth trialling, but it manages symptoms rather than addressing the load and strength issues underneath.
