PACE participants will begin up to 6 weeks prior to their scheduled TKR and continue until 12 weeks after their TKR. Participants will be given personalized weight, dietary, and physical activity goals. Participants will be encouraged to monitor their dietary intake and physical activity using their preferred method of self-monitoring. Participants will have regular contact with their coaches either in-person or over the telephone on a weekly or bi-weekly basis, based on preference during the first 14 weeks (from up to 6 weeks pre-op to 12 weeks post-op). Further, participants may opt to receive regular text messages or emails from coaches if they prefer. At 12 weeks, PACE participants will enter a maintenance period and not have any contact with coaches.
