Sugary drinks linked to arthritis of the knee

(WTVR) -  Sugary soft drinks are being linked to an unexpected ailment osteoarthritis of the knee.

Researchers followed more than 2,000 patients with arthritis in their knees.

X-rays show that patients who drink soda regularly, have a more narrow joint-space in their knees, especially men, and the results held whether or not the patients were overweight.

Researchers believe something in soft drinks may damage the knee-joint directly by limiting the amount of calcium absorption.
