Abstract
Introduction: Total knee arthroplasty (TKA) is a common surgical procedure that replaces the knee joint with a synthetic prosthesis to relieve pain and restore function in patients with severe joint diseases. Effective postoperative pain management is critical for recovery. Traditionally, opioids have been used, but concerns about side effects have spurred the search for alternatives such as peripheral nerve blocks. Objective: This study analyzes the efficacy of femoral nerve block (FNB) in postoperative pain management following TKA. Methodology: A literature review from databases like PubMed, Scopus, and Web of Science focused on studies since 2014. Search terms included "femoral nerve block," "postoperative pain management," "total knee arthroplasty," and "opioids," addressing systematic reviews and clinical trials. Results: FNB was found effective in reducing postoperative pain and opioid use. While continuous FNB provided moderate pain relief, other studies noted muscle weakness. Comparisons showed that adductor canal block (ACB) offered similar analgesia with less muscle impact. Discussion: Although FNB efficiently alleviates pain and decreases opioid consumption, it poses risks such as quadriceps weakness, impacting mobility. Emerging techniques like ACB and iPACK offer similar analgesic benefits with potentially fewer complications. Conclusion: FNB is valuable in managing postoperative pain after TKA, though careful consideration is required regarding muscle weakness. Multimodal strategies incorporating various nerve blocks can enhance recovery and reduce complications, underscoring the need for continued research to refine these approaches.
