Cingal (Hyaluronic Acid)

CINGAL® Hyaluronic Acid Injections for Knee Osteoarthritis

CINGAL® is a single-injection treatment designed to relieve pain and improve joint function in patients with knee osteoarthritis (OA).

It combines a corticosteroid with a high-concentration, cross-linked hyaluronic acid to restore the cushioning and lubricating properties of the knee. This can help reduce pain for up to 6-9 months.

CINGAL® offers a safe, effective, and convenient option for managing knee osteoarthritis and improving quality of life without surgery.

What is it used for?

Used in knee Osteoarthritis.

Arthritic knees tend to produce lower concentrations of hyaluronic acid which is used to lubricate the knee.

Without HA the knee is less shock absorbing and can be a cause of pain.

If you are not ready for surgery and over-the-counter and prescription pain medications no longer provide pain relief, talk to Dr Ibrahim about hyaluronic acid injections as an option for managing your knee pain.
