Viscosupplementation (Rooster Comb) Injections: These injections are a great treatment for knee pain. They are made from a natural substance called hyaluronic acid that has almost no side effects. They act like a lubricant in the knee and reduce both friction and pain. These injections can be seen advertised in the newspaper , and on TV. When they are used, they can sometimes delay or prevent a knee replacement. These injections are done in a series of 3 shots, and have no down time. This is also a same day procedure that is done in the office, rather than in the hospital.
Cingal™ is a mixture of hyaluronan combined with a steroid. Hyaluronan is a natural chemical found in high amounts in your joint tissues and in the fluid that fills your joints. When you have knee OA, there may not be enough hyaluronan in your knee joint and the quality may be lower than normal. Cingal™ adds hyaluronan to your knee joint, acting as a lubricant and shock absorber in the joint. Cingal™ also contains a steroid, triamcinolone hexacetonide, which provides short-term and long-lasting pain relief by reducing inflammation.
Arthrocentesis – Also called joint fluid aspiration, arthrocentesis is removal of joint fluid through a hollow needle inserted into the joint space of the knee. Although the purpose of removing joint fluid from the knee is usually so that it can be tested in the lab, removing excess fluid can also quickly ease pain and swelling. Often after withdrawing fluid, doctors use the same puncture site where the fluid was removed to inject a corticosteroid preparation and/or anesthetic into the knee joint to further relieve pain and inflammation.
