Neuromuscular training improves lower limb mechanics
NSAID evidence
Short courses effective for pain management during flares
Chronic NSAID use not supported for long-term management
No evidence that NSAIDs alter natural history
Injection therapy evidence
Corticosteroid injections not recommended
No high-quality evidence supporting injection therapy for apophysitis
Risk of patellar tendon weakening and avulsion fracture
Platelet-rich plasma (PRP) emerging but unproven
Limited evidence in OSD specifically
Reserve for refractory cases under specialist guidance
Surgical considerations
Reserved for <10% of patients
Persistent symptomatic ossicle after physeal closure
Ossicle excision and tibial tubercle debridement effective
Excellent outcomes when performed after skeletal maturity
Patient Discharge Instructions

What is Osgood-Schlatter Disease?
Pain and swelling below the kneecap at the bony bump on the lower leg (tibial tubercle)
Caused by repetitive stress on a growth area during rapid growth in active adolescents
A self-limiting condition that heals as bones mature; full recovery expected
Activity modification
Reduce high-impact activities that cause pain: running, jumping, kneeling
Stay active with low-impact alternatives: swimming, cycling, walking
Return to sports gradually when pain allows; pain >3/10 during activity means slow down
Wear a patellar tendon strap or knee pad during sports if it helps
Ice and pain relief
Ice the tibial tubercle for 15-20 minutes after activity
Ibuprofen or naproxen for pain flares (take with food as directed)
Acetaminophen as an alternative
Do NOT have a cortisone injection into the knee for this condition
Stretching home program
Quadriceps stretch: stand, bend knee behind you, hold ankle 30-60 seconds each leg
Hamstring stretch: sitting, straighten one leg, reach toward toes, hold 30 seconds
Perform stretches twice daily
Warning signs to return to the emergency department
Sudden severe knee pain after a forceful jump or kick
Inability to straighten the knee actively
Significant swelling, warmth, or redness of the knee joint
Fever with knee pain
Pain at rest or night pain that wakes you from sleep
Pain not improving despite 6-8 weeks of conservative management
Follow-up
Family doctor or sports medicine clinic in 4-6 weeks
Physical therapy referral if stretching and strengthening not improving symptoms
Most patients recover fully in 3-6 months; symptoms always resolve when bones stop growing
Reassurance: the bony bump may remain but will stop being painful
