简要总结
This study aims to predict risk factors of acute postoperative pain of the patients undergoing Total Knee Replacement Arthroplasty(TKRA).
详细描述
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.

结局指标
主要结局
Consumption of analgesics
时间窗: 48 hours
Cumulative consumption of Patient-Controlled Analgesia(PCA) and rescue analgesics is recorded.
Acute post operative pain
时间窗: 48 hours
Acute post operative pain is recorded on NRS(a pain scale ranging from 0 to 10. the higher number means the higher pain) at rest in an attempt to bent knee.
次要结局
- Preoperative anxiety and depression(one day before the surgery: 20 hours before the surgery)
- Diabetic neuropathy(one day before the surgery: 20 hours before the surgery)
- Pain expectation of acute postoperative pain(one day before the surgery: 20 hours before the surgery)
- Pain catastrophizing level(one day before the surgery: 20 hours before the surgery)
- Preoperative knee pain(one day before the surgery: 20 hours before the surgery)
- Demographic data(one day before the surgery: 20 hours before the surgery)
- Preoperative pain in other sites(one day before the surgery: 20 hours before the surgery)
