Core tip: Over the last decades, the number of total knee arthroplasty procedures performed has increasing dramatically. This very successful intervention, however, is associated with significant postoperative pain, and adequate postoperative analgesia is mandatory in order to allow for successful rehabilitation and recovery. The use of regional anesthesia and peripheral nerve blocks has facilitated and improved this goal. In contrast to patient controlled analgesia using opioids, patients with a regional anesthetic technique suffer from fewer adverse events and show higher patient satisfaction. This review provides a short overview of currently used regional anesthetic and analgesic techniques focusing related implications, considerations and outcomes.
