What is Orthovisc?
Orthovisc (hyaluronan) is similar to the fluid that surrounds the joints in your body. This fluid acts as a lubricant and shock absorber for the joints.
Orthovisc is used to treat knee pain caused by osteoarthritis.
Orthovisc is usually given after other arthritis medications have been tried without success.
You should not receive Orthovisc if you have a bleeding disorder, certain allergies, or an infection in your knee or in the skin around your knee.

an infection in your knee or in the skin around your knee.
