Summary
Currently, continuous adductor canal and popliteal-sciatic nerve blocks are used commonly for
lower extremity post-operative pain control, specifically for total knee arthroplasty and
foot/ankle surgery, respectively. A perineural catheter used to infuse local anesthetic for
postoperative analgesia may be placed at various locations along the target nerves.
Investigations of single-injection peripheral nerve blocks suggest that the onset of the
block might be faster with one location over the other; but, the success rates are
equivalent. However, remaining unknown is whether there is an optimal location to place a
perineural catheter as part of a continuous peripheral nerve block.
