Osgood-Schlatter Disease
Osgood-Schlatter disease is a common cause of knee pain in growing adolescents, typically affecting those between 9 and 14 years old who are active in running and jumping sports. It is not actually a disease but an overuse injury: repeated stress at the point where the patellar tendon attaches to the tibial tuberosity (a bony prominence just below the kneecap) causes inflammation and micro-injury at the growth plate. In severe or prolonged cases, a separate ossicle (bone fragment) can form at the attachment site. It usually resolves on its own once growth plates close, but can be painful enough to limit sports participation for months.

Symptoms
- Pain and tenderness directly at the bony bump below the kneecap
- Swelling at the tibial tuberosity
- Pain that worsens with running, jumping, kneeling, or going up stairs
- A visible bony prominence that may become permanently enlarged
- Pain typically in one knee, though bilateral in 20–30% of cases
- Symptoms that flare with activity and improve with rest
When to See a Doctor
See a paediatrician, sports medicine physician, or paediatric orthopaedic surgeon if your child has persistent knee pain that is limiting sports participation, if the pain is severe enough to cause a limp, or if symptoms have lasted more than 6 weeks without improvement. Most cases are straightforward to diagnose clinically without imaging.
Treatment Options
Activity modification and rest
The foundational treatment. Reducing or temporarily stopping activities that aggravate the tibial tuberosity (running, jumping, squatting) gives the growth plate time to recover. Complete rest from all sports is rarely necessary.
Ice and anti-inflammatory medication
Ice after activity and NSAIDs (ibuprofen, naproxen) help control pain and inflammation during flares. Not a cure, but useful for managing symptoms so the child can continue modified activity.
Physical therapy
Stretching the quadriceps and hamstrings reduces tension on the patellar tendon attachment. Strengthening exercises address muscle imbalances. A patellar tendon strap or knee sleeve can provide symptomatic relief during activity.
Watchful waiting
Most cases resolve completely once the growth plate closes (typically by age 14–16 in girls, 16–18 in boys). The permanent bony prominence, when present, is cosmetic and rarely causes problems in adulthood.
Surgery
Very rarely needed. Excision of a painful residual ossicle may be considered in skeletally mature patients who have persistent pain into adulthood after growth plate closure. Not appropriate during active growth.
Recovery Timeline
Mild cases: symptoms improve with 4–6 weeks of activity modification. Moderate to severe cases: 3–6 months of management, with periodic flares during growth spurts. The condition is self-limiting—virtually all patients are pain-free once skeletal maturity is reached, though the tibial tuberosity bump may remain.
Frequently Asked Questions
Will Osgood-Schlatter disease cause permanent damage?
In the vast majority of cases, no. The condition is self-limiting and resolves when the growth plate closes. A small minority of patients have a persistent ossicle that causes pain into adulthood, which can be addressed surgically if needed. The bony prominence at the tibial tuberosity often remains visible but is usually not painful.
Should my child stop all sports?
Usually not. Complete rest from sports is rarely required and often counterproductive—kids who stop entirely tend to lose conditioning and find it harder to return. The goal is relative rest: reduce intensity and volume to a pain-tolerable level. High-impact activities (basketball, soccer, track) may need more modification than swimming or cycling.
What type of doctor treats Osgood-Schlatter disease?
Paediatricians or primary care sports medicine physicians can manage most cases. A paediatric orthopaedic surgeon or sports medicine specialist is appropriate if symptoms are severe, if the diagnosis is unclear, or if the child is not improving with basic treatment.
