Viscosupplementation knee joint therapy is a medical procedure during which
lubricating fluid is injected into a knee joint. As its name implies,
viscosupplementation artificially supplements the joint fluid's natural
viscosity. By injecting a man-made hyaluronan into the knee,
doctors hope to temporarily lubricate the knee joint, thereby improving
function and perhaps even slowing the degeneration process.
It is a painless procedure and no admission is required.
viscosupplementation a small amount of hyaluronic acid, 2 mL- 8 ml, is injected directly into knee
joint capsule by orthopaedician with proper anitiseptic and aseptic
precautions. No anesthesia is required and patient goes home walking within 10
The Science- Why is it necessary?
healthy knee joint has up to 4 mL of joint fluid within the joint capsule.. Hyaluronic acid is a key component of the joint fluid. It
gives the joint fluid its viscous, slippery quality, which enables the bones'
cartilage-covered surfaces to glide against each other, thereby reducing joint
friction and adds cushion to protect joints during impact (e.g. weight-bearing
affected by osteoarthritis typically have a lower concentration of hyaluronic
acid in their joint fluid than healthy joints, and therefore less protection
against joint friction and impact.
Opinion of the specialist:
his experience of more than 100 such knee visscosupplementation injection patients.

Which patients benefit from this therapy?
candidates for viscosupplementation are people with knee osteoarthritis who
have failed to improve with other non-surgical treatments.
