BACKGROUND: Sleep quality declines in the immediate postoperative period following total knee arthroplasty (TKA). No prior study has prospectively analyzed the impact of mindfulness meditation (MM) on sleep quality following TKA. The purpose of this study was to determine whether MM administered in conjunction with TKA results in any improvement in Pittsburgh Sleep Quality Index (PSQI) at 2, 6, or 12 weeks postoperatively.
METHODS: Patients undergoing primary unilateral TKA were prospectively enrolled and randomized into 3 cohorts. The perioperative MM cohort received MM at the preoperative visit, the day preceding surgery, 3 days postoperatively, and 2 weeks postoperatively. The preoperative MM group only received MM at the preoperative visit. Controls received no MM. MM consisted of a video of 2 licensed professional psychologists guiding viewers through a 15-minute MM. Demographic data were collected and questionnaires completed at 2, 6, and 12 weeks postoperatively. Patients were excluded on the basis of prior alcohol/drug dependence and inability to present to in-person visits. An a priori analysis required 75 patients per cohort to achieve 80% power.
RESULTS: Two hundred eighty-two patients were enrolled and randomized to 3 groups: control (n = 94), preoperative MM (n = 94), and perioperative MM (n = 94). There were no differences between cohorts in age (P = .24), sex (P = .77), body mass index (P = .18), American Society of Anesthesiologists (P = .17), or length of stay (P = .18). No differences between cohorts in preoperative PSQI scores were noted (8.4 ± 4.1 control, 7.9 ± 3.8 preoperative MM, 7.8 ± 4.3 perioperative MM; P = .58). Two weeks postoperatively, there remained no PSQI differences between groups (10.7 ± 4.3 control, 10.8 ± 4.4 preoperative MM, 9.9 ± 4.4 perioperative MM; P = .33). This persisted at 6 weeks (10.1 ± 4.2 control, 10.0 ± 3.9 preoperative MM, 9.5 ± 4.4 perioperative MM; P = .62). At 12 weeks, PSQI returned to preoperative levels and there remained no difference among cohorts (8.7 ± 4.4 control, 8.3 ± 4.2 preoperative MM, 7.8 ± 4.1 perioperative MM; P = .264).
CONCLUSIONS: Mindfulness training did not improve postoperative sleep quality at any time point following TKA. Further studies are warranted, as improving sleep quality may enhance TKA rehabilitation.
LEVEL OF EVIDENCE: Therapeutic Level II.
