The proposed study has three objectives:
Objective 1. Develop KOA microsimulation model: To develop and validate a Knee-OA population-based microsimulation model (POHEM-KOA) using the previously developed POHEM-OA model.
Objective 2. Perform cost-effectiveness analysis of non-pharmacological therapies for KOA: To use POHEM-KOA in conducting a cost-effectiveness analysis of treatment strategies, including exercise therapy and weight reduction, targeted at obese and overweight early OA patients in Canada over the next 20 years [2013, 2033].
