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.
