Quick Answer

Rooster injections, also known as hyaluronan injections, relieve osteoarthritis pain in the knees by providing extra lubrication in the joint, states WebMD. The solution is similar to the knee's natural fluid, making it a safe supplement for those with mild-to-moderate arthritis symptoms. Several different hyaluronic acid medications are available, with the typical dosage varying between medications. Some require only a single injection. Others require a weekly injection for three to five weeks.

Doctors recommend hyaluronan injections for osteoarthritis patients who do not respond well to oral pain medications or physical therapy, maintains WebMD. After an initial injection, it takes four to 12 weeks for patients to experience pain relief. Common side effects for the treatment include joint swelling and pain. Most of the hyaluronan medications are not safe for patients with allergies to eggs or chicken products.
