If your knee feels stiff, achy, or like it's grinding bone-on-bone after years of activity, you may be dealing with osteoarthritis, a condition where the cartilage cushioning your joint gradually wears down. Viscosupplementation is a non-surgical treatment that supplements the joint's natural lubricating fluid to help ease that friction and support smoother movement.
At Modern Edge Sports & Orthopedic Medicine, board-certified specialist Dr. Michael Wong, DO performs viscosupplementation injections under ultrasound guidance to help place the medication precisely within the joint space. As part of an entirely non-surgical practice, he'll walk you through whether this treatment, or another option, best fits your knee, hip, or shoulder osteoarthritis and your longer-term activity goals.
If joint stiffness is holding you back from the activities you enjoy, schedule an appointment with our team to talk through whether viscosupplementation could be part of your care plan and to learn more about the timeline you can realistically expect.
So what is viscosupplementation? It's a treatment in which a gel-like substance called hyaluronic acid, similar to the fluid that naturally lubricates a healthy joint, is injected directly into the joint space.
In a healthy joint, this fluid cushions movement and reduces friction between bones. Osteoarthritis breaks that fluid down over time, which is part of why the joint starts to feel stiff or grinds during movement. Hyaluronic acid injections work by supplementing this lubrication, and their effect builds over a longer, multi-week timeline as the joint responds, which is different from how a corticosteroid injection works.
Several FDA-approved formulations, such as Durolane, Euflexxa, and Orthovisc, are available for this kind of treatment, and Dr. Mike will help determine which formulation fits your joint and insurance plan. If you're comparing options, our corticosteroid injections page explains that treatment's faster-acting, anti-inflammatory mechanism in more detail.
Viscosupplementation is most commonly used for injections for knee joint osteoarthritis, though your provider may consider it for the hip or shoulder as well. In select cases, it is also used off-label in other joints, such as the ankle or the base of the thumb, known as the carpometacarpal (CMC) joint, for appropriate candidates.
Dr. Mike typically discusses this option with patients who have mild to moderate arthritis and want a non-surgical way to support their joint before considering more invasive procedures. Because a gel injection in the knee works gradually, it tends to suit patients looking for an ongoing part of their joint care rather than immediate relief from a sudden flare-up.
It's easy to confuse different joint injections, so it helps to keep their mechanisms separate. Corticosteroid injections calm inflammation quickly but the relief is usually temporary. Viscosupplementation instead supplements joint lubrication over a longer stretch of weeks to months. Regenerative options such as PRP therapy and BMAC injections work through a different mechanism altogether, using concentrated growth factors or cellular components from your own body.
One additional consideration for patients managing diabetes is that hyaluronic acid injections do not affect blood sugar the way corticosteroid injections sometimes can, which is a factor Dr. Mike may weigh alongside your diagnosis and goals. Dr. Mike can help you understand which mechanism, or combination, fits your situation, since no single option is right for every patient.
Because viscosupplementation cost and coverage depend on your specific insurance plan and diagnosis, our team will review your benefits and any self-pay pricing with you directly. Many major insurance plans cover medically appropriate viscosupplementation treatment for knee osteoarthritis, and transparent self-pay options are available for patients who prefer them. Your first step is a visit with Dr. Mike to confirm whether viscosupplementation is appropriate for your joint.
Viscosupplementation is used most often for knee osteoarthritis, though it can sometimes help hip or shoulder arthritis as well. By supplementing the joint's natural lubricating fluid, it aims to reduce friction and support easier movement for patients who want a non-surgical option before considering more invasive procedures.
Unlike a corticosteroid injection, which can relieve pain within days, viscosupplementation works gradually over a period of weeks as the hyaluronic acid integrates with the joint's fluid. Most patients are advised to give the treatment several weeks before judging how well it's working for their knee.
Many major insurance plans cover hyaluronic acid injections when they're medically appropriate for diagnosed osteoarthritis, though coverage details vary by plan. Our team will verify your specific benefits before your visit and discuss self-pay pricing if that's a better fit for you.
Corticosteroid injections work quickly, often easing pain within days, but that relief is typically temporary. Viscosupplementation takes longer to build effect, usually over several weeks, because it works by supplementing the joint's natural lubrication rather than calming inflammation directly.
You may hear these injections nicknamed “rooster comb shots,” a reference to how some early hyaluronic acid formulations were sourced; today's formulations are produced differently, and Dr. Mike can walk you through which type may be used for your treatment. Which approach makes sense for you depends on your goals, diagnosis, and how you've responded to treatment in the past, and Dr. Mike will help you weigh both during your visit.
