What is Osgood Schlatter Disease?
Osgood–Schlatter disease is a common overuse condition affecting the growth plate (tibial tubercle) located just below the kneecap. It typically occurs in active children and adolescents during growth spurts, particularly when participating in sports that involve running, jumping, and rapid changes in direction.
What happens in Osgood–Schlatter disease?
The patellar tendon connects the kneecap to the shinbone. Repeated pulling from the quadriceps muscle can irritate the growth area where the tendon attaches to the tibia. This causes:
- Pain below the kneecap
- Swelling or a bony bump at the top of the shin
- Tenderness with kneeling or activity
- Tight thigh muscles
It is most common between:
- Boys: ~12–15 years
- Girls: ~10–13 years
Common symptoms
- Pain during or after sport
- Limping after exercise
- Pain when squatting, jumping, or climbing stairs
- Tight hamstrings or quadriceps
- A prominent bump below the knee
Symptoms often fluctuate depending on activity levels.
Physiotherapy management at Cumberland Physio Parramatta
1. Activity modification
The goal is usually load management, not complete rest.
Reduce activities that strongly aggravate symptoms:
- Repeated jumping
- Sprinting
- Deep squats
- High training volumes
Pain during sport is often acceptable if it stays mild and settles within 24 hours.
2. Stretching
Tight muscles increase tension on the tendon attachment.
Common stretches:
- Quadriceps stretch
- Hamstring stretch
- Calf stretch
- Hip flexor stretch
3. Strengthening
Progressive strengthening helps improve load tolerance.
Typical exercises:
- Straight-leg raises
- Wall sits
- Step-ups
- Glute strengthening
- Controlled squats
4. Tendon loading progression
Physios often progress through:
- Isometric exercises
- Slow resistance exercises
- Plyometrics
- Return-to-sport drills
5. Pain management
Helpful options may include:
- Ice after activity
- Patellar tendon strap
- Relative rest
- Temporary reduction in training load
Recovery time
Most cases improve gradually over:
- Several months to 1–2 years during growth
The condition usually resolves once growth plates mature, though the bump may remain permanently.
When to seek medical review
See a healthcare professional if:
- Pain is severe or constant
- There is major swelling/redness
- The knee locks or gives way
- Symptoms occur at rest/night
- There was a significant traumatic injury
Typical goals at Cumberland Physiotherapy Parramatta
- Keep the child active safely
- Reduce pain flare-ups
- Maintain strength and flexibility
- Gradually return to full sport participation
Good evidence supports exercise-based management and load modification rather than complete immobilisation in most cases.
