Background:

• Osteoarthritis of the joints is common.
  
• This can give rise to symptoms of pain, swelling and reduced range of movement.
  
• Patients' symptoms can range from mild to severe.
  

• One of the non-surgical options for treating this is known generally as Viscosupplementation injections. 
  
• This involves injecting a gel-like fluid known as Hyaluronic Acid (HA) into the affected joint.
  

• The goal of this treatment is to reduce pain, inflammation and restore function of the affected joint. 
  

• HA is a naturally occurring substance found in the synovial fluid of joints. 
  
• It behaves as a lubricant to allow bones to articulate smoothly over each other and has a mild anti-inflammatory effect.
  
• It is also a shock absorber for joints during loading and weight bearing. 
  

• People with OA have lower than normal concentrations of HA in their affected joints.

• There are several commercial HA preparations available.
  
• Most doctors will choose to use the preparation that they are most familiar with.
