The Washington Post (11/15, Squires) reported research now indicates that approximately one in four “adults suffer from chronic knee pain.” For the most part, “knee pain is...caused by osteoarthritis, a chronic condition that afflicts an estimated 30 million Americans of all ages.” While knee replacement is an option, “experts say there is strong interest in nonsurgical alternatives to cut joint pain and provide more mobility and a better quality of life.” Patients can “strengthen leg, hip and core muscles, engage in low-impact aerobic exercise and neuromuscular education,” lose weight, take medications to “help counter joint pain by reducing inflammation.”
