What Kind of Joint Injections Treat Osteoarthritis?

I have an elderly friend who has severe arthritis in her knee. What type of injections are given to treat arthritis?

For degenerative arthritis (osteoarthritis), cortisone injections and hyaluronic acid injection (Synvisc Hyalgan, Euflexxa, Supartz, Orthovisc, and others) are used. For inflammatory arthritis (such as rheumatoid arthritis), cortisone injections are used.

For more information, see Osteoarthritis and/or Rheumatoid Arthritis.

Thank you for your question.
