This study sought to determine whether using 1500/1200 mg of glucosamine hydrochloride and chondroitin sulfate (GH/CS) is effective, both separately and combined with exercise, compared to a placebo plus exercise program in improving physical function, pain, strength, balance, and mobility in older adults with knee osteoarthritis (OA). 89 subjects were randomized to either GH/CS or placebo group. Phase I was a 6-month trial comparing the effects of assignment to either GH/CS or placebo. Phase II added 6 months of exercise for both groups. The results showed that GH/CS group was not superior to the placebo group in function, pain, or mobility after both phases of the intervention.
