If all is well with the joint, then the fluid should be clear. However, if the joint's infected, the fluid will appear cloudy because of increased protein and abnormal cells in the joint fluid. Ultrasound detects thickened joint capsules and chip fractures. Once joint disease has been detected the question is how to treat or care for the horse. Another treatment of joint disease is hyaluronic acid, sold under brand names such as Legend .
Hyaluronic acid helps the joints produce good joint fluid.
Transferring fluid from a non-infected to the affected joint, once a common practice, is no longer required. Corticosteroid use is another treatment option. By reducing water movement in and out of the joint, corticosteroids help preserve the joint during the healing process. This is extremely helpful in repairing damaged cartilage, according to White. Other treatments for joint disease include arthroscopic exploration with diagnostic tools, flushing the joint, immobilization, and rest.
