A major joint injection delivers anti-inflammatory steroid or lubricating viscosupplement medication directly into a large joint — such as the knee, hip, or shoulder — to ease arthritis pain and improve day-to-day movement.
OVERVIEW
What a major joint injection is and how it works
A major joint injection is a targeted, minimally invasive procedure used to treat pain and stiffness in the body’s largest weight-bearing and high-mobility joints. Using image guidance, one of our physicians places medication precisely inside the joint capsule, where it can act on the source of inflammation rather than the surrounding muscle or soft tissue.
Two main types of medication are used, and your physician will recommend the option best suited to your diagnosis:
- Corticosteroid: a strong anti-inflammatory medication, often combined with a local anesthetic, that calms the swelling and irritation driving joint pain.
- Viscosupplement (hyaluronic acid): a gel-like fluid that supplements the joint’s natural lubrication. It is FDA-approved for knee osteoarthritis and is most commonly used in the knee.
CONDITIONS
What a major joint injection commonly treats
This procedure targets pain originating within the large joints, frequently from degenerative or inflammatory conditions affecting the knee, hip, or shoulder.
Commonly treats
Major joint injections are often considered when oral medications, activity modification, and physical therapy have not provided enough relief, or as part of a broader plan to keep you active.

YOUR VISIT
What to expect
Before
Your physician reviews your history, imaging, and prior treatments to confirm the injection is appropriate. Let us know about blood thinners, allergies, diabetes, or any active infection, as these may affect timing or medication choice. The procedure requires little preparation. Whether you can drive yourself home depends on the joint treated and whether any sedation is used, so our team will let you know in advance.
During
After cleaning the skin and applying a local anesthetic, your physician uses image guidance — typically ultrasound or fluoroscopy (live X-ray) — to direct the needle precisely into the joint. Guidance improves accuracy, especially in deeper joints like the hip. The medication is then injected. The injection itself usually takes only a few minutes, with the full appointment often under 30 minutes.
After
You may feel relief from the anesthetic within hours, though this can fade before the steroid or viscosupplement takes fuller effect over several days. Mild soreness at the injection site is common and usually settles with rest and ice. Many people return to normal activities the next day while avoiding strenuous use of the joint for a short period.
Results and follow-up
Because the medication is placed directly in the joint, the degree and duration of relief vary from person to person and by condition. Your physician will discuss realistic expectations and whether the injection may be repeated as part of your ongoing care.
QUESTIONS
Frequently asked questions
How long does relief from a major joint injection last?
Duration varies widely depending on the joint, the underlying condition, and the medication used. Some patients experience relief lasting weeks to several months, while others respond less predictably. Because individual results differ, your physician will set expectations specific to your situation and monitor how you respond.
What is the difference between a steroid and a viscosupplement injection?
A steroid injection reduces inflammation and can be used across many joints, while a viscosupplement (hyaluronic acid) injection supplements the joint’s natural lubrication and is FDA-approved for knee osteoarthritis. Your physician will recommend the option that best matches your diagnosis and goals.
Is the injection painful?
A local anesthetic is used to numb the skin first, so most patients feel only brief pressure or a pinch. Image guidance helps the needle reach the joint efficiently, which can minimize discomfort during the procedure.
How often can a major joint injection be repeated?
Steroid injections into the same joint are generally spaced out rather than given frequently, and your physician will recommend an interval that balances relief with joint health. Viscosupplement is often given as a single injection or a short series. We tailor the plan to your response and overall treatment goals.
