Risk factors and predictive model for acute postoperative pain after hip and knee arthroplasty

This study identified several factors closely related to APP after hip and knee arthroplasty and provided a basis for postoperative pain management through the developed predictive model. The research underscores the importance of comprehensive preoperative assessment and the implementation of targeted pain prevention measures. Future studies are recommended to expand the sample size and include multiple centers to enhance the generalizability and practicality of these findings.
