Mindfulness Meditation Intervention Study

The goal of this pilot study is to develop a randomized control trial study with sufficient power to definitely address if a preop mindfulness meditation intervention can improve post-total knee arthroplasty mental well-being or physical health compared to controls, and if a preop mindfulness meditation intervention can train resilience. The main questions it aims to answer are: 1. Is this preoperative mindfulness meditation study feasible at Hospital for Special Surgery? 2. Can we estimate a control and intervention group central tendency and variability to be used to determine sample size in future study? 3. Does a preoperative mindfulness meditation interventions improve post-total knee arthroplasty mental well-being or physical health compared to controls? Can preoperative a mindfulness meditation intervention train resilience (as measured by increased resilience score)? Participants will be randomly assigned to be in the intervention group or the waitlist control group. The intervention group gets the mindfulness mediation intervention prior to their day of surgery, and the control group will be given the mindfulness meditation intervention 90 days after their day of surgery. The waitlist control group allows for comparison between those who got the mindfulness meditation intervention prior to surgery and those who did not while still offering the potential benefits of the intervention after 90 days.
