What is the initial treatment for rotator cuff tendinopathy?

Initial Treatment for Rotator Cuff Tendinopathy

Exercise therapy combined with NSAIDs should be the first-line treatment for rotator cuff tendinopathy. 1, 2

Conservative Management Approach

Exercise Therapy

• Exercise therapy has demonstrated beneficial effects in decreasing pain and improving function in patients with rotator cuff-related symptoms without full-thickness tears 1, 2
• Exercise programs should focus specifically on:
  • Rotator cuff strengthening exercises 1
  • Scapular stabilization exercises 1
  • Range of motion exercises 1
• Both supervised and home-based physical therapy programs can lead to improvements in outcomes, though evidence quality is limited 1, 2
• Exercise therapy should be active and task-oriented to effectively reduce pain and disability 3

Pharmacological Management

• NSAIDs are recommended as first-line pharmacological treatment to reduce pain and inflammation 1, 2
• A single injection of corticosteroid with local anesthetic may provide short-term improvement in both pain and function for patients with persistent shoulder pain 2, 1
• Caution should be exercised with corticosteroid injections as they may inhibit healing and reduce tendon tensile strength 1
• Acetaminophen may be used as an alternative pain management option 3

Other Conservative Modalities

• Limited evidence supports the use of hyaluronic acid injections in nonsurgical management 2, 4
• Limited evidence does not support routine use of platelet-rich plasma (PRP) for rotator cuff tendinopathy or partial tears 2, 4
• Evidence is inconclusive for the use of iontophoresis, phonophoresis, TENS, ice, heat, or massage 2, 1

Treatment Algorithm

Initial Phase (0-6 weeks)

1. Activity modification to avoid aggravating movements 1
2. NSAIDs for pain control 1, 2
3. Begin structured exercise program focusing on:
   • Rotator cuff strengthening 1
   • Scapular stabilization 1
   • Range of motion exercises 1

Secondary Phase (if inadequate response after 6 weeks)

1. Consider a single corticosteroid injection for short-term pain relief 2, 1
2. Intensify physical therapy program 1
3. Consider advanced imaging (MRI, ultrasound) to assess for full-thickness tears if symptoms persist 1, 3

Tertiary Phase (persistent symptoms despite conservative management)

1. Surgical consultation may be appropriate for patients with persistent pain and functional limitations 1, 5
2. Note that surgery has not consistently demonstrated superior outcomes compared to continued conservative management for many patients 5

Special Considerations

Age and Comorbidities

• Strong evidence indicates that older age is associated with higher failure rates and poorer outcomes after rotator cuff repair 2
• Moderate evidence supports the association of poorer outcomes in patients with comorbidities 2
• Patients with diabetes will have higher retear rates and poorer quality of life after rotator cuff repair 2

Common Pitfalls to Avoid

• Overreliance on corticosteroid injections may lead to tendon weakening and potential rupture 1
• Neglecting exercise therapy, which forms the cornerstone of conservative management 1, 6
• Premature surgical intervention before adequate trial of conservative management 5
• Failing to develop a return-to-work plan early in collaboration with the patient and other stakeholders 3
• Unnecessary diagnostic imaging in the absence of red flags or failure to respond to conservative treatment 3, 1
