A commonly used drug may prevent osteoarthritis in people who suffer severe joint injuries. About 27 million Americans suffer from arthritis, and more than three million of those cases result from a joint injury, often in the knee, that provokes slow and steady cartilage deterioration. A new study from MIT suggests that a steroid drug currently used to treat inflammatory diseases could also prevent osteoarthritis from ever developing in those people, if given soon after the injury.
