Abstract

Sleep disturbance after total knee arthroplasty (TKA) has not been studied 6 months after surgery. A prospective study was conducted on 34 primary, unilateral TKA patients preoperatively until 6 months postoperatively. Sleep quality was measured using the Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale. Pain was measured on a visual analog scale. Sleep quality worsened from baseline during the first 6 weeks postoperatively (P = .03), but improved at 3 and 6 months (P = .003). Pain scores decreased from baseline over all time points, and there was no correlation between sleep quality and pain. The Epworth Sleepiness Scale did not change over time. This study can be used to counsel TKA patients to expect initial sleep disturbances that improve by 3 months.
