The goal was to determine if glucosamine and/or can Drayton treats pain related to OA of the knee and could help prevent structural damage. The study found no benefit for pain relief for the study group compared with the placebo group.

The researchers included only studies that were – blind, placebo-controlled, randomized trials of at least four weeks duration and tested glucosamine’s effectiveness in treating 0A and the knee or hip. 15 studies were included in the analysis and the investigators applied a statistical formula to evaluate these studies, giving the larger studies more weight.
