Summary
Patients suffer from moderate to severe pain after TKA. Patients are asked to begin
functional exercise as early as possible after surgery, and that requires adequate control of
postoperative pain. Regional anesthesia divides into non-motor sparing peripheral nerve
blocks as femoral n. block and sciatic n. block and motor sparing peripheral nerve block as
adductor canal block and IPACK but these blocks have many drawbacks.
So new studies found that a modified 4 in-1 block blocks all these nerves and produces
adequate analgesia without sparing areas.
