Single-injection Modified 4 in 1 Block as Postoperative Analgesia in Total Knee Arthroplasty

• Target enrollment: 0
• Participant gender: All

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.
