Does regional anesthesia increase the risk of perioperative nerve injury in patients undergoing total knee arthroplasty?
Regional anesthesia techniques can be used in TKA without increasing the risk of perioperative nerve injury, though recovery from such injuries may be impaired.
Risk for PNI after TKA was unchanged by the use of RA techniques. This finding supports the notion that the known benefits of RA for patients undergoing TKA can be achieved without increasing risk of neurologic injury. However, in rare situations when PNI occurs, complete recovery may be less likely if it develops after peripheral nerve blockade.
