Abstract:
BACKGROUND:Pain is the main reason for the recovery of knee function after total knee arthroplasty. OBJECTIVE:To explore and analyze the influencing factors of pain after total knee arthroplasty.METHODS:160 patients with knee osteoarthritis underwent total knee arthroplasty. At 12, 24 and 48 hours after total knee arthroplasty, patients were evaluated with visual analogue scale (VAS) and knee function was assessed with KSS score preoperatively and 90 days postoperatively. Factors, including operation time, age, gender, body mass index, anesthesia method, and preoperative score of KSS were analyzed by Pearson correlation and multiple linear regression. These statistics method also was used to analyze the relationship between the postoperative 90 days score of KSS and postoperative VAS score at each time point. RESULTS AND CONCLUSION:(1) Pearson correlation analysis and multiple linear regression analysis showed that operation time, gender, and body mass index had been correlated positively with VAS score at 12, 24 and 48 hours postoperatively. (2) Patient age had been correlated negatively with VAS score at 12, 24 and 48 hours postoperatively. (3) VAS score at 12, 24 and 48 hours postoperatively had been correlated negatively with KSS score at 90 days postoperatively. (4) Gender, operation time, body mass index and age are al the influencing factors of the pain after total knee arthroplasty. Pain after total knee arthroplasty affects the recovery of knee function.
