Viscosupplementation for OA

Viscosupplementation Injections
Osteoarthritis (OA)


  • 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.

  • It is worth noting that viscosupplementation injections can also be used in other musculoskeletal conditions (e.g. tenosynovitis, bursitis)- its use is not just limited to OA.
