Osteoarthritis is the most common form of arthritis. It is more common in women than in men, with incidence increasing sharply around the age of 50. And it can cause complications - including the inability to perform activities of daily living and spinal stenosis in cervical and lumbar osteoarthritis. So it is vital that we get the diagnosis and management of this condition right. In this BMJ Best Practice podcast on osteoarthritis, Kieran Walsh talks to Fadi Badlissi, Assistant Professor at Harvard Medical School and Director of the Musculoskeletal Medicine Unit at Beth Israel Deaconess Medical Center in Boston.
