BACKGROUNDUse of popliteal nerve blocks (PNBs) as an alternative or adjunctive therapy to traditional methods of pain control (e.g., systemic or spinal anesthesia and opioids) is increasingly popular in foot and ankle surgery. METHODSWe reviewed online databases for literature on PNBs in foot and ankle surgery to analyze the various techniques and positioning used, the influence of drugs on their efficacy, and possible complications associated with their use. Thirty articles were identified with a predefined search criteria, followed by a review process for relevance. RESULTSPatient demographics, procedure specifics, and block techniques, such as anesthetic used, can impact the duration and success of a PNB. Administration with ultrasound guidance proved superior to nerve stimulation, and preoperative administration was superior to postoperative administration. CONCLUSIONSPNBs are an effective method to control postoperative pain with minimal complications, leading to decreased analgesic use, earlier discharge, and higher patient satisfaction.
