    AbstractThis study examined the effects of sleep quality on early recovery after total knee arthroplasty. A total of 148 patients were randomized 1:1 to receive either zolpidem or placebo for 2 weeks. VAS pain scores (rest, ambulation and night), range of motion (ROM), total amount of opioid analgesics and antiemetics taken, postoperative nausea and vomiting (PONV), sleep efficacy and satisfaction were recorded. It was found that patients taking zolpidem achieved greater improvement in quality of life and reported better satisfaction. Patients in the intervention group had lower pain score and took less antiemetics. Moreover, a significant correlation between sleep quality and ROM was detected. These results demonstrated that improved sleep quality is beneficial to patients' post-TKA recovery.Copyright © 2015. Published by Elsevier Inc.
