Joint injections of cortisone may not be safe

The extremely common procedure of injection of cortisone into joints has until recently been considered safe if not overused. New evidence is showing that may not be true. A new study in the journal Radiology showed that 8% of patients who had injections in the hips or knees had complications that worsened the state of the joint. Recent studies show little or no benefit. The American Academy of Orthopedic Surgeons do not recommend them.
