Researchers are evaluating the effectiveness of two types of nerve blocks—Adductor Canal Block alone and Adductor Canal Block combined with the IPACK block—in reducing pain and the need for pain medicine after knee surgery, specifically total knee arthroplasty. This study aims to find out which method provides better postoperative pain relief using ultrasound-guided techniques. Participants are divided into two groups: one receives a single-shot Adductor Canal Block before surgery, and the other receives both the Adductor Canal Block and an IPACK block, also before surgery. Both groups will have access to a patient-controlled intravenous morphine device after surgery to manage pain. The study compares these two approaches to assess their impact on pain and opioid use. During the study, researchers will measure opioid consumption and pain scores at rest and during movement within the first 24 hours after surgery. They will also monitor side effects like nausea and vomiting during this period. Participants will be followed starting from the preoperative phase through at least 24 hours postoperatively to evaluate pain control and adverse effects.

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Day of surgery and immediate postoperative period
Participants receive either a preoperative adductor canal block alone or combined with an iPACK block under ultrasound guidance before knee surgery. Postoperative pain is managed with intravenous patient-controlled analgesia containing morphine.
1 preoperative visit and 1 postoperative visit (in-person)
Duration - 24 hours after surgery
Participants are assessed for opioid consumption, pain scores, and adverse effects during the first 24 hours after surgery.
1 follow-up visit within 24 hours post-surgery
