Cracking, popping joints may foretell arthritis

Grating, cracking or popping sounds around joints may predict future arthritis, especially in the knees, according to a recent US study.

Among thousands of people with no knee pain who were followed for three years, a quarter of them had noisy knees.

Yet they made up three-quarters of the cases of symptomatic knee arthritis that emerged by the end of the study period, the researchers found."Many people who have signs of osteoarthritis on X-rays do not necessarily complain about pain," said lead study author Grace Lo of Baylor College of Medicine in Houston, Texas. - REUTERS
