Medicine, Vol. 164, February 1999.

Sixteen-week randomised, double-blind, placebo-controlled crossover study design was implemented. Thirty-four males from the US Navy diving and special warfare community with pain and radiographic cartilage degeneration of the knee or low back were randomised into two groups, intervention (Cosamin®DS) and placebo. A summary score incorporated results of pain and functional questionnaires, physical examination scores and running times. Changes were presented as a percentage of the patient's average score. The authors reported significant improvement among patients in the knee intervention group in comparison the placebo group.
