Knee Osteoarthritis Disabling Pain Program for the Brazilian Unified Health System

This is a Randomized Clinical Trial to compare two interventions for reducing knee pain and improving knee function of patients with knee osteoarthritis. Sixty participants will be randomly allocated to one of the intervention groups, either a knee educational program or a combination of knee educational program and medical interventions. Participants will be assessed primarily on function and pain, as well as other secondary outcomes at baseline, at the end of the interventions, and three months after the end of the interventions.
