Cushion the Joint.
Walk with Ease.
Are you suffering from 'bone-on-bone' knee pain but terrified of a total knee replacement? Our precision, ultrasound-guided Hyaluronic Acid (gel) injections lubricate dry, arthritic joints—acting like a shock absorber so you can return to the life you love.
Greasing the Rusty Hinge
A healthy knee joint is surrounded by a thick, slippery liquid called synovial fluid. This fluid acts exactly like motor oil in a car engine, preventing the cartilage and bones from grinding together when you walk or climb stairs. However, if you have Knee Osteoarthritis, this fluid dries up and becomes watery. Without that essential 'oil,' your joint becomes a rusty hinge. The cartilage wears away, leading to agonizing 'bone-on-bone' friction, severe stiffness in the morning, and the inability to walk long distances.
Popping daily pain pills (NSAIDs) only hides the pain; it does nothing to fix the dry, grinding joint. Viscosupplementation is the mechanical solution. Dr. Rabara injects a premium, highly concentrated Hyaluronic Acid (gel) directly into the joint capsule. This thick gel instantly replenishes your body's natural 'motor oil.' It coats the damaged cartilage, restores the shock-absorbing cushion, and allows the knee to glide smoothly again, frequently delaying the need for a total knee replacement for years.
Joint Conditions Treated with Gel Injections
Is Hyaluronic Acid Right For You?
Ideal indications
You have chronic knee OA with daily stiffness, grinding, or popping.
You have tried steroids, but the pain returned too quickly.
Your stomach cannot tolerate daily NSAIDs due to ulcers or kidney issues.
You want to delay knee replacement surgery as long as possible.
Clinical precautions
You have an active, hot, red skin infection over the knee.
You have severe avian (bird/egg) allergies (non-avian options available).
Steroids vs. Gel: Which Do You Need?
Corticosteroids (Steroids)
Powerful anti-inflammatory that stops acute swelling and pain rapidly.
Hyaluronic Acid (Gel)
Thick gel that physically cushions the joint and protects remaining cartilage.
Replacement (Surgery)
Highly invasive overhaul of bone and metal hardware.
What to Expect After Your Gel Injection
The Rest Phase
Your knee will feel full and tight. Avoid heavy lifting or vigorous exercise for 48 hours to allow the gel to settle.
The Lubrication Phase
The gel coats the joint. You will notice a decrease in grinding and stiffness when using stairs.
Maximum Protection
Provides 6-12 months of relief. Pairing this with Physical Therapy extends the life of the injection even further.
Clinical Science & Technical Details
For our medical colleagues and highly analytical patients, we provide these transparent technical details on the pathophysiology and interventional protocols.
Explore the Clinical Science: Rheological Properties of Hyaluronic Acid
The pathophysiology of Osteoarthritis (OA) involves both the mechanical degradation of articular cartilage and the severe depletion of endogenous Hyaluronic Acid (HA) within the synovial fluid. In a healthy knee, HA molecules provide critical elastoviscous properties: acting as a viscous lubricant during slow, low-impact movements, and transforming into an elastic shock absorber during rapid movements.
In an osteoarthritic knee, the HA concentration is reduced. Viscosupplementation introduces exogenous HA (such as Synvisc) directly into the joint. This restores mechanical viscoelasticity and triggers an analgesic effect by coating nociceptors, potentially stimulating endogenous HA production over time.
Detailed Diagnostic Pathways & Kellgren-Lawrence Grading
Dr. Rabara utilizes the Kellgren-Lawrence (KL) grading system to stage OA via X-rays. High efficacy is observed in KL Grade 2 and 3. While KL Grade 4 ("bone-on-bone") still benefits from palliative pain relief, HA injections serve as a vital "bridge therapy" for these severe cases to delay surgery.
The Synovial Environment: Managing Effusion & Inflammation
Ensuring the joint environment is primed is critical. Dr. Rabara screens via Ultrasound. If severe effusion ("water on the knee") exists, the inflammatory fluid will degrade the gel. In these cases, Dr. Rabara performs a two-step intervention: aspiration and steroids first, followed by HA gel once the inflammation subsides.
Inside the Procedure: Sonographic Accuracy Rates vs. Blind Palpation
"Blind" injections have an accuracy rate of 65-80%. Missing the capsule means the expensive gel is wasted in fat tissue. At our Vigan clinic, Dr. Rabara utilizes live High-Frequency Ultrasound to guarantee 100% intra-articular delivery, ensuring maximum return on your medical investment.
Molecular Degradation and Repeat Intervention Timelines
While the gel is metabolized over months, the functional benefits last longer by breaking the inflammatory cycle. HA injections are repeatable every 6-12 months to defer knee replacement surgery indefinitely.

Don't Waste Expensive Medicine: The Ultrasound Advantage
The MSK Ultrasound Diagnosis
Dr. Rabara uses live Diagnostic Ultrasound to look inside your knee first, ensuring the joint capsule is accurately identified before the injection.
Precision Image-Guided Injection
While watching the ultrasound screen in real-time, Dr. Rabara guides the needle precisely into the joint space, ensuring 100% medication delivery.
Joint Mobilization & Protection
Immediately after, we gently move the knee to evenly distribute the gel throughout the joint capsule, allowing you to walk out the same day.
