Overview
A joint injection delivers medication, most often a corticosteroid with a numbing medicine, directly into a joint such as the knee, hip or shoulder.
Joint injections can reduce inflammation and pain from arthritis and related conditions. They are often used alongside exercise and physical therapy.

How it works
The clinician cleans the skin and uses landmarks, ultrasound or X-ray guidance to place the needle into the joint and inject the medication.
Who it may be for
- Osteoarthritis or inflammatory arthritis
- Joint pain that has not improved with other measures

Your exam and imaging decide whether this treatment is appropriate for you.
What to expect

- During: a short procedure, often in the office.
- After: rest the joint for a day or two.
