Total knee arthroplasty and its postoperative period can be very painful. Usually patients undergoing locoregional or general anesthetic techniques to which peripheral nerve blocks are associated for postoperative analgesia, within which femoral nerve block is the most widespread an adequate analgesic quality of the anterior compartment of the knee. It is widely described in the literature that blockage of the adductor canal or Hunter confers an analgesic quality similar to that achieved with the femoral block without objectifying that motor block that can limit its use for rapid rehabilitation. Recently also described in the literature, the blockade that is defined as IPACK (Infiltration between Popliteal Artery and Capsule Knee) or SPANK (Posterior Articular Sensory Nerves of the Knee) achieves an adequate analgesia of the posterior compartment of the knee. We believe that the combination of these two peripheral nerve blocks associated with the usual anesthetic technique may result in better analgesic quality in our patients and a lower consumption of opioids in the form of rescue.
