It is also among the most expensive condition to treat when joint replacement surgery is required. Future projections of the prevalence of OA predict an increase in prevalence, mainly due to the aging of the population and obesity.\n\nTotal knee replacement (TKR) is the end-stage solution for patients with knee OA.
