About this study
Official title: Dual Subsartorial Block Versus Adductor Canal Block Versus Femoral Nerve Block for Postoperative Analgesia in Patients Undergoing Total Knee Arthroplasty: A Randomized Clinical Trial
This study aims to compare the effect of dual subsartorial block (DSB), adductor canal block (ACB), and femoral nerve block (FNB) for postoperative analgesia in patients undergoing total knee arthroplasty (TKA).
Read the detailed description
Total knee arthroplasty (TKA) offers increased joint mobility and painless ambulation to patients. Femoral nerve block (FNB) is commonly used to relieve postoperative pain and opioid consumption.
Adductor canal block (ACB) is a common analgesic intervention for postoperative pain control following TKA. The dual subsartorial block (DSB) is a novel procedure-specific and motor-sparing regional analgesia (RA) technique that may reduce overall postoperative opioid consumption when used in conjunction with multimodal analgesia.

What is being measured
The primary outcome is the main question the study is designed to answer.
Time to the 1st rescue analgesia
Time to the first request for the rescue analgesia (time from the end of surgery to first dose of morphine administrated).
Measured: 24 hours postoperatively
Secondary outcomes (4)
Intraoperative fentanyl consumption
Additional fentanyl bolus dosages of 1 µg/kg IV will be administered if heart rate or mean arterial blood pressure elevated more than 20% of the baseline (after exclusion of other causes than pain).
Measured: Intraoperatively
Degree of pain
Each patient will be instructed about postoperative pain assessment with the visual analog scale (VAS). VAS (0 represents "no pain" while 10 represents "the worst pain imaginable"). VAS will be assessed at PACU, 2, 4, 6, 8, 12, 18 and 24 h postoperatively.
Measured: 24 hours postoperatively
Degree of patient satisfaction
Degree of patient satisfaction will be assessed on a 5-point Likert scale patient satisfaction (1, extremely dissatisfied; 2, unsatisfied; 3, neutral; 4, satisfied; 5, extremely satisfied).
Measured: 24 hours postoperatively
Incidence of adverse events
Incidence of adverse events such as bradycardia, hypotension, nausea, vomiting, respiratory depression, pruritus, or any other complication.
Measured: 24 hours postoperatively

This study aims to compare the effect of dual subsartorial block (DSB), adductor canal block (ACB), and femoral nerve block (FNB) for postoperative analgesia in patients undergoing total knee arthroplasty (TKA).
Detailed description
Total knee arthroplasty (TKA) offers increased joint mobility and painless ambulation to patients. Femoral nerve block (FNB) is commonly used to relieve postoperative pain and opioid consumption.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jun 2026; AzTrials last refreshed its copy on 8 Nov 2026.
