Background: Knee osteoarthritis (OA) causes pain and long-term
disability with annual healthcare costs exceeding $185 billion in the United States.
Few medical remedies effectively influence the course of the disease. Finding
effective treatments to maintain function and quality of life in patients with knee
OA is one of the national prio... read morerities identified by the Institute of Medicine. We are
currently conducting the first comparative effectiveness and cost-effectiveness
randomized trial of Tai Chi versus a physical-therapy regimen in a sample of patients
with symptomatic and radiographically confirmed knee OA. This article describes the
design and conduct of this trial.
