Management of Tendinitis
The cornerstone of tendinitis management is relative rest combined with eccentric strengthening exercises and cryotherapy, while NSAIDs provide short-term pain relief but do not improve long-term outcomes. 1
Initial Conservative Management (First-Line Treatment)
Activity Modification
- Continue activities that do not worsen pain - complete immobilization should be avoided to prevent muscle atrophy and deconditioning 1
- Reduce repetitive loading of the affected tendon
- No clear evidence exists for optimal rest duration, but most patients recover within 3-6 months 1
Cryotherapy
- Apply ice through a wet towel for 10-minute periods - this is the most effective method based on systematic review evidence 1
- Provides short-term pain relief by reducing tissue metabolism and blunting inflammatory response
- Particularly effective in acute inflammatory tendinopathies
Eccentric Strengthening Exercises
- This is the most evidence-based intervention for reversing degenerative changes 1
- Proven beneficial in Achilles and patellar tendinopathy, likely helpful in other tendinopathies 1
- Tensile loading stimulates collagen production and guides proper alignment of newly formed collagen fibers
- Stretching exercises are widely accepted as helpful adjuncts
Pharmacologic Management
NSAIDs
- Effective for short-term pain relief only - no long-term benefit 1
- Topical NSAIDs are preferred as they reduce pain while eliminating gastrointestinal hemorrhage risk associated with systemic NSAIDs 1
- Cannot be recommended over other analgesics based on current evidence
- Most useful in acute inflammatory tendinitis; less clear benefit in chronic degenerative tendinopathy
Corticosteroid Injections
- Use with significant caution - may provide acute pain relief but do not alter long-term outcomes 1
- Critical pitfall: Injecting into tendon substance causes deleterious effects including reduced tensile strength and predisposition to spontaneous rupture 1
- Peritendinous injections have unknown effects and should be used cautiously
- May be more effective than oral NSAIDs for acute-phase pain relief, but this advantage is temporary 1
Adjunctive Therapies
Orthotics and Braces
- Safe and widely used (tennis elbow bands, shoe orthotics) 1
- Helpful for correcting biomechanical problems like excessive foot pronation
- Limited data supporting effectiveness, but clinical experience and patient preference should guide use 1
Advanced Modalities
- Extracorporeal shock wave therapy (ESWT): Appears safe and effective but expensive; further research needed 1
- High-volume injections: Emerging evidence shows promise for pain reduction 2
- Therapeutic ultrasonography, iontophoresis, phonophoresis: Uncertain benefit with weak evidence 1
When to Consider Surgery
Reserve surgery for patients who fail 3-6 months of conservative therapy 1
- Surgery is effective in carefully selected patients
- Typically involves excision of abnormal tendon tissue and longitudinal tenotomies
- Mechanism of surgical healing promotion not entirely understood
Important Clinical Pearls
Terminology Matters
Most patients presenting to primary care have chronic degenerative tendinopathy ("tendinosus"), not acute inflammatory "tendinitis" 1. This distinction is critical because anti-inflammatory treatments may not address the underlying degenerative pathology.
Natural History
Approximately 80% of patients fully recover within 3-6 months with conservative management 1
Diagnostic Imaging
- Plain radiography: Limited utility for soft tissue but may reveal bony abnormalities 1
- Ultrasonography: Useful for showing tendon thickening and decreased echogenicity
- MRI: Most sensitive and specific for detecting chronic degenerative changes
- Reserve imaging for unclear diagnoses - most cases are clinical diagnoses 3
Common Pitfalls to Avoid
- Do not inject corticosteroids directly into tendon substance - risk of rupture 1
- Avoid complete immobilization - leads to atrophy and deconditioning 1
- Do not rely on NSAIDs for long-term management - they provide only temporary symptom relief 1
- Recognize that most "tendinitis" is actually degenerative tendinopathy requiring different treatment approach 1
