Brief summary: Osteoarthritis (OA) is one of the most common joint disorders, affecting not only the joints but also the surrounding muscles, which become weak. Resistance exercise reduces pain and improves function in patients with OA of the knee. Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used by patients with OA to reduce pain and thereby maintain the ability to perform daily activities. However, there is accumulating evidence for a negative effect of NSAIDs, thus many patients with OA are treated with dietary supplementations such as glucosamine and chondroitin sulfate, and some studies show a beneficial effects on cartilage and pain. However, their effect on OA symptoms and cartilage remains controversial. On the other hand creatine supplementation has also been observed to show promising effects when combined with resistance training exercise in the elderly, but the evidence is limited in terms of knee osteoarthritis. For this reason the purpose of this study is to determine the effects of creatine supplementation as compared to glucosamine/chondroitin sulfate in the management of knee osteoarthritis when combined with resistance training exercise.
