Total Knee Replacement can be performed under the combination of posterior lumbar plexus block plus sciatic nerve block. The investigators can have the same outcome by performing instead of posterior lumbar plexus block more peripheral nerve blocks. More specifically under the combination of sciatic nerve block plus femoral nerve block plus obturator nerve block.
