Viscosupplement (Hyaluronic Acid) Injections for Knee Arthritis
If knee arthritis pain is slowing you down and you’re not ready for surgery, viscosupplement injections—often called hyaluronic acid or “gel” injections—may help. These injections are designed to improve joint lubrication and cushioning, potentially reducing pain and helping you move more comfortably.
Viscosupplementation is an injection of hyaluronic acid, a naturally occurring substance found in healthy joint fluid. In people with osteoarthritis, the joint fluid can become thinner and less effective at cushioning. These injections aim to restore some of that “shock absorber” effect.
You may be a candidate if you:
Have knee osteoarthritis diagnosed by an orthopedic provider
Have pain or stiffness that affects walking, stairs, work, exercise, or sleep
Haven’t gotten enough relief from activity modification, physical therapy, weight management, bracing, anti-inflammatory medications, or previous injections
Want to delay or avoid knee replacement (when appropriate)
Your provider will help confirm whether viscosupplementation makes sense for your specific knee and goals.
The injection is performed in-office and typically takes only a few minutes.
Your provider cleans the skin and injects the medication into the knee joint.
Some patients feel mild pressure; discomfort is usually brief.
Depending on the product, you may receive one injection or a short series.
After the injection:
You can usually return to normal activities the same day.
Avoid high-impact activity for 24–48 hours.
Mild soreness or swelling can occur and usually resolves quickly.
Some patients notice improvement within a few days, while others see the best results after several weeks. Relief can last several months for some people, but results vary.
Viscosupplementation is not a cure for arthritis. It’s a tool to help manage symptoms and keep you moving.
No. Cortisone is a steroid used to reduce inflammation. Viscosupplementation is hyaluronic acid designed to improve joint lubrication.
Coverage varies by plan and product. Our team can help verify benefits and pre-authorization requirements when needed.
Often yes, depending on your knee and diagnosis. Your provider will advise.
