Osteoarthritis or Other Joint Problems: Some people call it “wear and tear” arthritis or degenerative joint disease. There are numerous risk factors including age, weight, prior injury and genetics.
Knee Stiffness or Loss of Motion: Common symptoms of arthritis include morning stiffness, swelling, reduced range of motion, pain when walking or getting up/down from a chair, pain with activity, cracking and popping of the knee.
Knee pain: You may not even realize you have arthritis because it tends to sneak up on patients slowly over time. Early detection is key to effective non-surgical treatment options.

Lubrication: Synovial fluid forms a thin, slippery layer over the cartilage, allowing the bones in your knee to glide effortlessly against each other with minimal friction.
Shock Absorption: It acts as a cushion, absorbing the impact and stress from daily activities like walking, standing, getting up/down from a chair, kneeling, running, and jumping.
Nutrient Supply: Cartilage does not have its own blood supply, so it relies on synovial fluid to deliver vital oxygen and nutrients to keep it healthy and functioning properly.



Living with knee osteoarthritis can feel like driving on a worn-out tire – the protective cartilage in your joint thins, leading to painful friction and reduced natural lubrication.
Viscosupplementation is a treatment designed to restore cushioning and lubrication to your arthritic knee. We gently inject a natural, gel-like substance – similar to your body's own healthy joint fluid (hyaluronic acid) – directly into the knee.
Think of it as adding a "viscous" (thick and slippery) "supplement" right where your knee needs it most.
Lubricates: The gel helps your joint surfaces glide more smoothly, reducing painful rubbing and grinding.
Cushions: It acts like a shock absorber, protecting your knee from impact.
Restores Comfort: By improving lubrication and cushioning, many patients experience significant pain relief and improved mobility.
Precision Matters: X-Ray Guided Injections
To ensure the gel reaches the precise area within your joint for maximum effectiveness, all our viscosupplementation injections are performed under X-ray guidance. This helps us deliver the relief you're looking for without any guesswork.
