Help us better understand how mood and pain influence activity after knee replacement! As part of our research study being conducted at Northwestern University, patients will be asked to download a smartphone application and respond to 2 questions, 6 times per day for two nonconsecutive weeks after the knee replacement. Patients will also be asked to wear a physical activity monitor on their waist during these 2 week periods. Participants will receive $50 for completing each 1 week period, for a total of $100.
