Abstract

Knee osteoarthritis is the most common form of joint disease and is a major cause of pain and physical disability among the elderly. Although, numerous treatments have been developed to treat osteoarthritis, no definitive treatments with high efficacy and low risk have been identified until now. In recent years, it has been reported that nutraceuticals may be good candidates for the management of knee osteoarthritis. This paper describes the efficacy of nutraceuticals for treating knee osteoarthritis in terms of pain and structural change. To accomplish this, this paper reports on the analysis of randomized, placebo-controlled, clinical trials that were published prior to December 2011.

Key words: Nutraceuticals, knee, osteoarthritis, pain.
