From the Research
For adhesive capsulitis, corticosteroid injections are generally considered the best injectate option, particularly triamcinolone acetonide (20mg) mixed with local anesthetic, as it has been shown to be as effective as a 40mg dose 1. The injection should be delivered into the glenohumeral joint or subacromial space under ultrasound guidance when possible to ensure accurate placement.
- A single injection is often sufficient, though some patients may require a repeat injection after 6-8 weeks if symptoms persist.
- Corticosteroids work by reducing inflammation in the joint capsule, which helps decrease pain and improve range of motion during the painful freezing phase of the condition.
- This allows patients to more effectively participate in physical therapy, which remains essential for long-term recovery.
- Alternative injectates include hyaluronic acid and saline hydrodilatation (capsular distension), but these have shown less consistent results than corticosteroids 2, 3.
- Patients should be informed that improvement may not be immediate, with maximum benefit typically occurring 2-3 weeks post-injection, and should continue prescribed stretching exercises to maintain and improve mobility gains.
- Early injection may be considered to shorten the natural history of adhesive capsulitis, as it has been shown to improve outcomes at both short- and long-term follow-ups 4.
