How long does paediatric physiotherapy take to work for Osgood-Schlatter disease?

Osgood-Schlatter disease affects the growth area below the knee where the tendon attaches. Repeated running, jumping and rapid changes in training can keep loading this area. Physiotherapy cannot stop growth, so the aim is to improve tolerance while symptoms settle. Progress may mean less pain after sport, easier stairs, stronger thighs and hips, or completing drills with better control.

The plan may include thigh and hip strengthening, calf or thigh flexibility work, activity modification and a gradual return to impact. A visible bump below the knee can remain even when symptoms improve.

Follow the agreed activity limits and complete exercises with the technique taught by the therapist. Record which activities bring on pain and whether discomfort settles with rest. Increase running or jumping in stages rather than returning to the full training schedule at once. Tell the physiotherapist about tournaments, school sports and footwear so the plan fits real demands. Ice or other symptom measures should be used only as advised.

Contact the care team if pain is worsening, appears at rest or at night, causes a limp, or does not settle with the agreed reduction in load. Seek urgent care after a forceful injury if the child cannot bear weight, the knee suddenly swells, or there is severe pain or inability to straighten the leg.

What level of running and jumping is suitable now? Which symptom means the training load is too high? How will strength and readiness for sport be tested? Should both legs follow the same exercise plan? When should persistent pain prompt imaging or an orthopaedic review?
