The Health Impact of Mindfulness Based Stress Reduction on Total Knee Arthroplasty

The Health Impact of Mindfulness Based Stress Reduction on Total Knee Arthroplasty: A Pilot Study

Despite surgical success of total knee arthroplasty (TKA), reports of dissatisfaction and poor outcomes including increased pain, reduced function for daily activities, and compromised psychological health are common. Interventions to improve TKA outcomes are primarily education-focused, however there is little support for efficacy. Evidence suggests that mindfulness based stress reduction (MBSR) is effective for improving both physical and mental health, which are factors implicated in negative post-operative TKA outcomes. The efficacy of this empirically supported intervention on TKA outcomes has not been assessed. The proposed pilot study will conduct a randomized controlled trial to evaluate the feasibility and efficacy of pre-surgical MBSR on post-surgical outcomes. Post-operative pain (severity and catastrophizing), functioning (interference and illness impact), quality of life, emotional distress (anxiety and depression) and sleep will be assessed in pre-surgical MBSR and compared to treatment as usual. This pilot will provide an opportunity for TKA patients to receive an intervention that may improve outcomes. Further, it will provide insight into the relationship between pre-surgical MBSR and post-operative TKA outcomes, which will assist in the development of MBSR adaptations to less time intensive, and potentially more accessible, future offerings.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Forty-five participants on the waitlist for a TKA will be recruited from Concordia Hospital Hip and Knee Institute - a facility that performs 800 TKA's per year. Participants will be divided into two groups: the pre-operative MBSR group (30 participants, divided into two MBSR groups), and the treatment-as-usual (TAU;15 participants). The individuals in the pre-operative MBSR group will receive a pre-operative 8-week community-based MBSR course taught by a certified instructor, which includes group classes lasting 2.5 hours a week, 45-minutes of home practice 6 days per week, a 1-hour orientation session at the beginning, and a full-day silent retreat at the end. During the orientation, participants will complete the study measures for this study. Two weeks prior to the surgery at the pre-anesthesia clinic, all patients will receive another set of short self-reported questionnaires. All patients will subsequently receive post-operative questionnaires at the following regularly scheduled post-operative appointments: 6-8 weeks after surgery, and at 6 month and 1 year follow-ups. Clinic personnel, who are blinded to assignment, will administer these measures with all other regularly distributed clinical measures. Clinic personnel will also review the chart to inform researchers as to what physical condition contributed to the need for a TKA. The TAU group will have the opportunity to enroll in an MBSR course following the completion of the study (after approximately 1 year), at no cost.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: pre-operative MBSR
Pre-operative MBSR is a condition where individuals will receive a pre-operative 8-week community-based MBSR course, which includes group classes lasting 2.5 hours a week, 45-minutes of home practice 6 days per week, a 1-hour orientation session at the beginning, and a full-day silent retreat at the end. During the orientation, participants will complete the study measures for this study.
Behavioral: Pre-operative MBSR
A MBSR program typically consists of 8 weekly 2.5 hour sessions, home practice (typically 45 minutes per day, 6 days per week), and one day retreat. During the program, participants engage in a number of mindfulness practices (e.g., body scan, mindful movement, meditation) and discussions of their experiences, with the aim enhancing awareness to moment-to-moment experiences in a non-judging and accepting manner.
Other Names:
  • mindfulness based stress reduction
No Intervention: treatment-as-usual (TAU)
The individuals in the TAU group will receive their treatment as usual.
