What are cartilage modifying agents?
This group of compounds is defined by several characteristics: • These compounds either occur naturally in joint tissues, or are structurally similar to compounds occurring naturally in joint tissues • These compounds are not only structural building blocks of joint tissue, but also have a recognisable, reproducible effect on the metabolism of joint tissues. They do not mask joint problems, but instead have overall beneficial effects on cartilage, helping to slow the progression of joint cartilage breakdown. Cartilage modifying agents are available in both injectable and oral forms. Examples of oral cartilage modifying agents include glucosamine and chondroitin sulfate. An example of an injectable chondroprotective agent is hyaluronic acid administered directly into the joint by an orthopaedic specialist.
