Initial Management of Patellar Tendinitis in Children

Introduction to Patellar Tendinitis

  • The American Academy of Pediatrics and other medical societies recommend beginning treatment with relative rest, scheduled NSAIDs, and eccentric strengthening exercises for a child with patellar tendinitis 1

First-Line Conservative Management

  • Implement relative rest by avoiding activities that reproduce pain while maintaining general activity to prevent deconditioning and muscle atrophy 1
  • Complete immobilization should be avoided as it leads to muscular weakness 1
  • Use scheduled NSAIDs (oral or topical) for pain relief during the acute phase, particularly to allow participation in physical therapy 1
  • Topical NSAIDs eliminate the gastrointestinal hemorrhage risk associated with oral formulations, making them preferable in pediatric patients 1
  • Eccentric strengthening exercises form the cornerstone of rehabilitation, reducing symptoms, increasing strength, and promoting tendon healing 1

Treatment Duration and Expectations

  • Continue conservative management for 3-6 months before considering any advanced interventions 1, 5
  • Most patients (approximately 80%) achieve full recovery within this timeframe with appropriate conservative treatment 6

Diagnostic Considerations

  • Ensure proper diagnosis: patellar tendinitis is uncommon at age 7; consider alternative diagnoses including apophysitis or inflammatory conditions 2, 3

Advanced Interventions

  • Extracorporeal shock wave therapy is safe and noninvasive for chronic cases unresponsive to initial management 1
  • Corticosteroid injections should be used with extreme caution in children, as they may inhibit healing, reduce tensile strength, and predispose to spontaneous rupture 1
  • Surgery is reserved only for cases failing 3-6 months of conservative therapy and involves excision of abnormal tissue and longitudinal tenotomies 1, 5
