Osteoarthritis (OA) is a chronic condition and the world’s most common degenerative joint disease that affects the joints – primarily the hands, knees, and hips – resulting in pain, limited mobility, daily activity and quality of life.

Osteoarthritis and joint degeneration

Osteoarthritis is very common in people over 45 years of age, people with an active lifestyle, active athletes and leisure sportsmen. Osteoarthritic joints have a lower concentration of synovial fluid (or: hyaluronic acid) in their joint fluid. As the principal role of hyaluronic acid is to reduce friction between the articular cartilage of synovial joints during movement, low concentration of this substance may accelerate the joint degeneration process.

Supplementing the joint fluid’s natural viscosity with viscosupplementation, by adding hyaluronic acid to the existing joint fluid, is a proven effective treatment to:

  • improve the shock-absorbing properties of the body’s own synovial fluid
  • reduce pain over several months, increase mobility, and improve joint movement
  • provide a clinically effective alternative to anti-inflammatory/anti-rheumatic drugs
  • potentially slow OAprogression
