What is the expected duration of relief for cortisone versus gel injections?

✓ Accepted answer

Corticosteroid (cortisone) injections typically provide pain relief for 6 to 12 weeks, while hyaluronic acid gel injections usually last between 6 and 12 months. This significant difference in longevity dictates the frequency of repeat treatments and long-term management strategies for joint pain.

• Onset of Action: Cortisone works rapidly, with patients often feeling better within 24 to 72 hours. In contrast, gel injections require 4 to 6 weeks to reach full therapeutic benefit as the viscous fluid integrates into the joint structure.
• Treatment Frequency: You are generally limited to 3 to 4 cortisone injections per year to avoid side effects. Gel injections are administered as a series of 1 to 5 shots and are typically repeated every 6 months, offering more sustainable coverage.
• Mechanism and Long-Term Health: Cortisone reduces acute inflammation but may accelerate cartilage loss with repeated use. Gel injections lubricate and cushion the joint, having neutral to protective effects on cartilage preservation over time.
• Cost and Coverage: In the US, a cortisone injection typically costs $20 to $75 with insurance, while a gel series ranges from $60 to $150. Both are generally covered by Medicare, though gel therapy requires specific documentation of diagnosis and prior treatment failures.
