Overview
About Knee Lubrication Injection / Viscosupplementation
In knee osteoarthritis, the natural joint fluid (synovial fluid) loses its lubricating and shock-absorbing properties. Hyaluronic acid (HA) injections — known as viscosupplementation — replenish this fluid, restoring lubrication and cushioning within the knee joint. The procedure involves one or a series of weekly injections and is suitable for patients with mild to moderate knee arthritis seeking non-surgical relief.
Key Benefits
Restores natural joint lubrication lost due to arthritis
Pain relief lasting 6–12 months — much longer than steroid injections
Improves joint mobility and reduces stiffness
Non-surgical OPD procedure — no downtime or hospital admission
Can delay or avoid the need for knee replacement in suitable patients
Frequently Asked Questions
What is viscosupplementation made of?
Viscosupplementation uses hyaluronic acid, a naturally occurring substance found in healthy joint fluid. The injected HA supplements the depleted natural fluid in arthritic knees.
How many injections are needed?
Depending on the product used, treatment involves 1 single injection or a series of 3–5 weekly injections. Your doctor will recommend the best protocol for your condition.
How long does the relief last?
Most patients experience pain relief lasting 6–12 months. The treatment can be repeated as needed.
Who is the best candidate for viscosupplementation?
Patients with mild to moderate knee osteoarthritis who have not had adequate relief from physiotherapy and oral medications but are not yet ready for surgery are ideal candidates.
Is viscosupplementation different from a steroid injection?
Yes — steroid injections reduce inflammation and work faster (3–7 days) but last shorter (4–12 weeks). Viscosupplementation takes longer to work (2–4 weeks) but provides longer-lasting relief (6–12 months) and actually supplements the joint's natural lubrication.
