Description

INTRODUCTION:

Patients undergoing total knee arthroplasty (TKA) are often subjected to immediate postsurgical pain and disruption of sleep. Recent studies have explored the role of postoperative sleep disruption using subjective assessments, however the literature on objective markers of sleep quality remain sparse. The aim of this pilot study was to assess objective measures of sleep quality in the immediate postoperative period following TKA.

METHODS:

Patients undergoing primary unilateral TKA at a level two medical center were enrolled in a prospective study in which they wore wearable sleep tracking devices (WHOOP, USA) for at least a week prior to surgery and for three weeks postoperatively. Objective markers of sleep, including resting heart rate (RHR), heart rate variability (HRV), hours of sleep, number of sleep disturbances per hour, hours of deep sleep, hours of rapid eye movement (REM) sleep, and restorative sleep (deep and REM sleep combined) were recorded. The mean preoperative baseline values were compared to mean values over the first four postoperative weeks.

RESULTS:

A total of eight patients were enrolled in the study, with a mean age of 65±10 years. The mean hours of deep sleep (0.7 vs. 1.1; p=0.043) and restorative sleep (1.7 vs 2.3; p=0.043) were decreased in the first postoperative week compared to the fourth postoperative week. There were no other significant differences regarding any other outcomes.

CONCLUSION:

This pilot study suggests that patients undergoing TKA have disruptions in deep and restorative sleep in the immediate postoperative period. Further study is warranted with a greater sample size to further explore trends in postoperative sleep quality following TKA.
