para-sartorial compartment block in knee surgery

Conditions: Knee Osteoarthritis; Knee Injuries; Knee Disease; Knee Arthritis

Summary: selective blockade of the saphenous nerve branches is among the regional anesthesia techniques in knee surgery. in this block, analgesia is provided without motor block and is an essential advantage in terms of early mobilization in the postoperative period. blockage of motor branches causes a delay in mobilization and increases the risk of falling. the vastus medialis and its medical femoral cutaneous branch are rich in the femoral triangle. effective postoperative analgesia is provided by a femoral triangle (triangle) blockade. the intermediate femoral cutaneous nerve courses over the sartorius muscle. anatomically, the femoral triangle follows a separate path. when the femoral triangle and the blockade of the intermediate femoral cutaneous nerve are combined, it is called pskb block. parasartorial compartment block (pskb); is based on the blockade of the branches of the saphenous nerve, the two largest sensory nerves from the femoral nerve to the knee, and is predicted to provide effective postoperative analgesia in knee arthroplasty.
