Injections for Arthritic Knees – Viscosupplementation

  • Osteoarthritic synovial fluid has reduced elasticity and viscosity, reduced molecular weight and reduced hyaluronan concentration.
  • Viscosupplementation with Hyaluronan replaces and replenishes diseased synovial fluid with a temporary synovial fluid prosthesis that has long-term clinical benefits.
