Hyaluronic acid injections (viscosupplementation) — often called "gel shots" — add a gel-like substance to an arthritic joint to improve cushioning and lubrication. Most commonly used for knee osteoarthritis, they can help reduce pain and improve mobility, and at Wimmer they are delivered with image guidance when it adds precision.

What hyaluronic acid ("gel shots") does
Hyaluronic acid is a substance naturally found in healthy joint fluid. In an arthritic joint, its quality and quantity decline. Supplementing it with a "gel shot" can help restore cushioning and lubrication, easing pain and supporting smoother movement for many patients.
Who it may help
- Knee osteoarthritis
- Joint stiffness and 'bone-on-bone' discomfort
- Patients seeking non-surgical options
- Those not ready for, or wanting to delay, joint replacement
What to expect
After evaluation and ultrasound, the injection is placed precisely into the joint. Some plans use a single injection; others a short series. We'll explain the specific product and schedule that fits your situation.
