Hyaluronic Acid Knee Injections (Gel Shots) in Lighthouse Point, FL

Hyaluronic acid joint injections, also called viscosupplementation or knee "gel shots," place a lubricating gel directly into an arthritic knee to ease pain and stiffness. At Rebuild Regen Medical Clinic in Lighthouse Point, they are one of several non-surgical options we consider for knee osteoarthritis, alongside PRP injections, knee decompression and regenerative biologics.
The treatment manages symptoms. It does not regrow cartilage or reverse arthritis, and we say so up front. For the right patient it can make walking, stairs and sleep more comfortable for a period of months, with a quick in-office visit and little downtime.
What Hyaluronic Acid Does in a Healthy Knee
Hyaluronic acid is a natural component of synovial fluid, the fluid that fills the joint capsule. It gives that fluid its thick, slippery quality, so it cushions the joint under load and lets the cartilage surfaces glide. In osteoarthritis, the concentration and quality of hyaluronic acid in the joint fall, and the fluid becomes thinner and less protective.
An injection supplements that fluid with a purified hyaluronic acid gel. Beyond lubrication, laboratory research suggests hyaluronic acid may also have anti-inflammatory effects inside the joint, which is one reason relief can outlast the time the gel itself stays in the knee.
Who Is a Good Candidate
Hyaluronic acid products in the United States are approved by the FDA for pain from osteoarthritis of the knee in patients who have not found enough relief from conservative care such as exercise, physical therapy, weight management and simple pain relievers. You may be a candidate if you have:
- Knee osteoarthritis confirmed by examination and imaging
- Pain and stiffness that limit walking, stairs or standing
- Mild to moderate joint-space narrowing rather than bone-on-bone collapse
- Not enough relief from exercise, therapy or oral medication, or a reason to avoid long-term anti-inflammatory pills
- A wish to delay or avoid knee replacement surgery
Hyaluronic acid is generally not the right choice for an acute injury, a knee that is hot and swollen from infection or gout, or advanced arthritis where the joint has fully collapsed. Use in the hip, shoulder or other joints is off-label, and we discuss it case by case. If your knee pain comes from a meniscus tear, tendon or ligament instead of arthritis, a different treatment usually fits better; see knee pain for how we sort that out.
What a Visit Looks Like
Evaluation first. We review your symptoms, history, prior treatments, medications and any X-rays or MRI. If you do not have recent imaging, we will tell you whether it is needed before treatment.
The injection. The skin is cleaned and may be numbed. If the knee is swollen, excess fluid may be drawn off first. The hyaluronic acid is then injected into the joint space. The injection itself takes a few minutes, and most patients walk out of the office on their own.
Afterward. We usually advise avoiding strenuous activity, long standing and heavy lifting for about 48 hours. Ice can help with any soreness at the injection site.
Single Injection or a Series?
Hyaluronic acid products differ in their concentration and molecular weight, so the schedule depends on the product chosen. Some are given as a single injection; others are given as a series of three to five injections spaced about a week apart. Your provider will explain which product is being recommended and why.
When Relief Starts and How Long It Lasts
Unlike a cortisone shot, hyaluronic acid does not work overnight. Patients who respond typically notice improvement over several weeks, and in published studies relief has often lasted several months, sometimes up to about six. Some patients do not respond. If a course helps, it can be repeated when symptoms return, commonly no sooner than about six months later.
How Hyaluronic Acid Compares With Cortisone and PRP
| Cortisone (steroid) | Hyaluronic acid | PRP | |
|---|---|---|---|
| What it is | Anti-inflammatory steroid | Lubricating gel that supplements joint fluid | Concentrated platelets from your own blood |
| How fast it works | Days | Several weeks | Gradual, over weeks |
| Typical duration | Weeks to a few months | Several months in responders | Often 6 to 12 months in trials |
| Main limitation | Repeated use may affect cartilage | Mixed evidence; symptom relief only | Usually not covered by insurance |
Randomized trials comparing the three for knee osteoarthritis have generally favored PRP at six and twelve months, which is why PRP is often our first suggestion for early to moderate arthritis. Hyaluronic acid remains a reasonable option for patients who want an FDA-approved device, have insurance coverage for it, or have not responded to other care.

What the Evidence Says
The research on hyaluronic acid is genuinely mixed. Some trials and reviews show modest improvements in pain and function, especially in patients with milder arthritis; others find results close to placebo. The American Academy of Orthopaedic Surgeons' 2021 knee osteoarthritis guideline does not recommend it for routine use, while other specialty groups still consider it an option for selected patients. We share that picture honestly and help you decide whether it is worth trying for your knee.
Risks and Side Effects
Hyaluronic acid injections are generally well tolerated. The most common effects are temporary pain, warmth, swelling or stiffness in the knee for a day or two. Less commonly, a stronger inflammatory flare can occur. As with any joint injection, there is a small risk of infection or bleeding, which is why we use sterile technique and review blood thinners beforehand. Tell us if you have allergies to bird proteins, feathers or eggs, since some products are derived from rooster combs.

Frequently Asked Questions
Are hyaluronic acid injections the same as knee gel shots?
Yes. "Gel shots," "rooster shots" and viscosupplementation all refer to hyaluronic acid injections into the knee joint to supplement the natural lubricating fluid.
Do hyaluronic acid injections hurt?
Most patients feel pressure and a brief sting. The skin can be numbed first, and any soreness afterward usually settles within a day or two.
How soon will I feel better after a hyaluronic acid injection?
Hyaluronic acid works gradually. Patients who respond usually notice less pain and stiffness over several weeks rather than days.
How long do hyaluronic acid knee injections last?
In patients who respond, relief often lasts several months, sometimes up to about six. A course can be repeated when symptoms return.
Are hyaluronic acid injections covered by insurance?
Many insurance plans, including Medicare, cover hyaluronic acid injections for knee osteoarthritis when specific criteria are met, such as documented arthritis and failure of earlier treatments. Coverage depends on your plan, so call (954) 953-4208 to ask how your visit would be handled.
Is hyaluronic acid or PRP better for knee arthritis?
Trials comparing them have generally favored PRP at six and twelve months, but hyaluronic acid is FDA-approved for knee osteoarthritis and may be covered by insurance. Your provider will help you weigh the two for your knee.
Can hyaluronic acid be injected into the hip or shoulder?
Hyaluronic acid products are FDA-approved for the knee. Use in other joints is off-label and is considered case by case after an evaluation.
