Effect of nighttime total knee arthroplasty on prognosis / 中国组织工程研究

ABSTRACT

BACKGROUND: Whether nighttime surgery will affect the safety and prognosis of patients has been controversial. OBJECTIVE: To compare the safety and prognosis of daytime surgery versus nighttime surgery in patients receiving total knee arthroplasty. METHODS: Data of 712 patients who received unilateral total knee arthroplasty from January 2015 to January 2018 in the Binzhou Medical University Hospital were retrospectively analyzed. Of the patients, 615 cases were treated by total knee arthroplasty during daytime hours (800-1800) and the other 97 patients were treated by total knee arthroplasty during nighttime hours (1801-759). The perioperative and postoperative conditions of the two groups of patients were compared. This study was approved by the Medical Ethics Committee of Binzhou Medical University Hospital, China (approval No. LW2016013). RESULTS AND CONCLUSION: (1) Perioperative period The operation time in the nighttime surgery group was shorter than that in the daytime surgery group (P 0.05). (2) Prognosis There was no significant difference in motion range and knee joint function KSS score between the two groups (P > 0.05). (3) The results showed that nighttime surgery did not increase the incidence of adverse reactions after total knee arthroplasty, and did not affect the prognosis of patients.
