Ultrasound-guided Adductor Canal Block for Total Knee Replacement

Completed · Phase 4

Conditions studied: Complications; Arthroplasty, Knee Injuries

In brief

Total knee arthroplasty is associated with intense early postoperative pain. Fast track recovery programs including early therapy protocols and early hospital discharge are being implemented at various hospitals. The postoperative analgesic pain regimen should enhance functional recovery in addition to providing efficient analgesia with minimal side effects. Adductor canal blockade is commonly used to provide postoperative analgesia for total knee arthroplasty (TKA) surgery. The investigators hypothesize that an ultrasound guided adductor canal block will lower narcotic consumption and improved overall satisfaction compared to ultrasound guided sham block with normal saline (placebo) for patients undergoing minimally invasive TKA surgery.
