Analgesic Efficacy of Preemptive Stepwise Infiltration Anesthesia for Perioperative Analgesia After TKA

This is a single-center prospective cohort study in which patients were evaluated by inclusion and exclusion criteria before total knee arthroplasty (TKA). Eligible patients will be included in this study after signing the informed consent form. Before TKA, the patients will be randomly assigned to either a preemptive stepwise infiltration anaesthesia (PSIA) group or a postoperative local infiltration analgesia (PLIA) group and administered different pain management protocols during surgery. Clinical evaluation will be conducted at baseline, before surgery, and at 6, 12, 24, 48, and 72 hours postoperatively, as well as during follow-up visits at 3 weeks, 6 weeks and 6 months postoperatively. All patients voluntarily participated in the study and signed informed consent. During the treatment period, all prospective patients underwent clinical evaluation at the end of total knee arthroplasty and 6, 12, 24, 48, 72, and 96 weeks later, aimed at comparing the postoperative pain and inflammatory response between PSIA and PLIA, to explore the optimal perioperative analgesic modality for TKA.
