Randomized Controlled Trial Comparative Study
Preemptive Femoral Nerve Block Could Reduce the Rebound Pain After Periarticular Injection in Total Knee Arthroplasty.
We evaluated the effectiveness of postoperative pain management using intraoperative periarticular injection (PAI) and/or electromyography-guided preoperative femoral nerve block (FNB) in knees undergoing total knee arthroplasty (TKA). ⋯ PAI was more effective than FNB during the early (0-8 hours) postoperative period after TKA. Patients treated with PAI, however, experienced rebound pain at 24 hours. The combination of PAI and FNB may provide greater postoperative pain management than either alone for the first 24 hours after TKA.
