CONCLUSION: The COVID-19 lockdown had a significant impact on pain, joint function, physical function, and physical activity in patients with end-stage hip and knee OA. Since no study has yet investigated the development of clinical symptoms of patients with end-stage hip and knee osteoarthritis (OA) waiting for arthroplasty surgery, the purpose of this study was to investigate the course of (1) pain, (2) functional impairment, (3) mental health, and (4) daily activities during the course of COVID-19 lockdown. The present study hypothesized that the COVID-19 lockdown will limit physical activity, which will consequently increase clinical symptoms and decrease physical and mental function in patients with end-stage hip and knee OA.	./cache/cord-283843-qgpxauj1.txt	./txt/cord-283843-qgpxauj1.txt
