Emergency Room Treatment of Achilles Tendon Injury

Initial Management

The American Academy of Orthopaedic Surgeons recommends applying a protective splint or boot that limits dorsiflexion to protect the tendon, allowing protected weight-bearing, and arranging urgent orthopedic consultation within 2 weeks 1, 2
Early protected weight-bearing (within ≤2 weeks) with dorsiflexion limitation is recommended rather than complete non-weight-bearing, as suggested by the American Academy of Orthopaedic Surgeons 1

For partial tears or tendinopathy, the American Academy of Orthopaedic Surgeons suggests beginning activity modification, ice application, protected weight-bearing with heel lift, and NSAIDs for pain control 2
Apply ice through a wet towel for 10-minute periods to reduce inflammation and provide short-term pain relief, as recommended by the American Academy of Orthopaedic Surgeons 2
Prescribe NSAIDs for pain relief (topical formulations can avoid gastrointestinal side effects), as suggested by the American Academy of Orthopaedic Surgeons 2

Early mobilization (by 2-4 weeks) with protective devices allows quicker return to activities during the first 6 months compared to traditional casting, according to the American Academy of Orthopaedic Surgeons 1
For conservative management, if no improvement occurs after 6 weeks of initial treatment, referral to a podiatric foot and ankle surgeon is recommended, as suggested by the American Academy of Orthopaedic Surgeons 2

Never inject corticosteroids into or around the Achilles tendon in the acute setting, as recommended by the American Academy of Orthopaedic Surgeons 3, 2
Local corticosteroid injections can inhibit healing, reduce tensile strength, and significantly increase rupture risk, according to the American Academy of Orthopaedic Surgeons 3, 2

Emphasize the importance of compliance with the protective device and activity restrictions, as suggested by the American Academy of Orthopaedic Surgeons 1
Patient compliance to protocol is critical to prevent re-rupture, particularly with early weight-bearing programs, according to the American Academy of Orthopaedic Surgeons 1
Approximately 80% of patients with tendinopathy fully recover within 3-6 months with conservative outpatient treatment, as reported by the American Academy of Orthopaedic Surgeons 3
