Mindfulness Meditation Intervention Study

This study will investigate the effect of a preoperative mindfulness meditation intervention (MMI) on outcomes for total knee arthroplasty (TKA) patients at the Hospital for Special Surgery in a randomized controlled trial. Mindfulness meditation is a practice well-known to psychology research based on sustained attention on the present and a non-judgment of one's current situation. It has been used for numerous psychological issues including stress, anxiety, and depression. This intervention group will be compared against a waitlist control group (patients will be told they are on a waitlist to receive the mindfulness intervention, which will occur after data collection has finished for their group). This control has been utilized in several mindfulness meditation studies. Measures of anxiety, depression, resilience, pain and pain unpleasantness, and overall physical and mental health will be taken after randomization, but before the intervention (or being told they are on the waitlist). Overall physical and mental health measures will also be taken on the day of surgery and final surveys will be collected at 90 days post-op. 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.
