Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients undergoing bilateral TKRA are recruited. The time interval between the surgery of each leg is within 2 weeks. Before each surgery, patients will be asked to conduct questionnaires of Hospital Anxiety and Depression Scale(HADS) and Pain Catastrophizing Scale(PCS). In addition, the patients will have their preoperative knee pain(measured by Knee injury and Osteoarthritis Outcome Score), preoperative pain in other sites, expectation of postoperative pain(measured by Numerical Rating Scale), and morbidity of diabetic neuropathy recorded. Demographic factors including age, sex, and BMI of patients will be collected. Twenty four and forty eight hours after completion of the surgery, each patient will be asked to report thier acute postoperative pain on Numerical Rating Scale.

This study aims to find out risk factors of acute postoperative pain, including identical surgical history within 2 weeks, in patients undergoing bilateral TKRA.
