Viscosupplementation (Monovisc, Orthovisc)

Viscosupplementation, such as Monovisc or Orthovisc, is the injection of a clear gel-like substance containing hyaluronic acid into the knee. Hyaluronic acid is a naturally occurring substance found in the synovial fluid of the knee joint. The injection of hyaluronic acid into the joint is thought to lubricate the cartilage (much like oil lubricates an engine), thereby reducing pain. A single injection of Monovisc can help alleviate OA knee pain for up to 6 months.

These injections usually provide 9-12 months of relief (will vary per patient). 

* a portion of hyaluronic acid products may be covered under your private insurance plan. Contact your insurance provider to check if you have coverage
