Hyaluronic Acid (HA) Injections

Hyaluronic Acid (HA) is a naturally occurring substance found in synovial joint fluid, where it acts as a lubricant and shock absorber. This procedure involves injecting a purified form of HA directly into the joint using CT guidance to help restore lubrication and improve joint function. It is commonly used to treat osteoarthritis.

The full treatment is performed over three appointments. Each injection must be two weeks apart. Each appointment will take approximately 15 minutes.

There is little to no downtime following injections. You should be able to return home immediately after your appointment and resume normal daily activities.

Benefits of this procedure may be experienced immediately, however can take up to 8 weeks from the initial appointment to take effect.

This procedure provides the following benefits:

  • Stimulates production of normal, non-inflamed joint fluid

  • Protects residual cartilage within the joint
