Osteoarthritis (OA), also referred to as degenerative joint disease, is the most common form of arthritis. Osteoarthritis breaks down the cartilage in joints and causes pain, swelling and reduced motion. It can occur in any joint, but usually it affects hands, knees, hips, spine or lower back. Dr. Hirsh, Dr. Singh, Dr. Kapelow, Javier Chiriboga, and Physician Assistant Evan Abramsky specialize in painless, safe injections to areas affected by OA, giving relief to many patients who are affected by this debilitating disease.
