"The Effect of Adductor Canal Block Performed With Postoperative Thigh Tourniquet Application on Pain After Total Knee Arthroplasty"
Turkey (Türkiye)60 participantsStarted 2026-03-01
Plain-language summary
The biggest fear for patients undergoing knee replacement surgery is that persistent pain felt at the back of the knee postoperatively. While regional anesthesia is generally successful at numbing the front of the knee, managing pain in the posterior (back) area is not always easy. In this study, we tested a new method designed to alleviate pain in the back of the knee and improve patient comfort.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria Patients aged 40-85 years, with a BMI of 18-35 kg/m², and an ASA physical status of I-III who underwent total knee arthroplasty (TKA) under spinal anesthesia were included. Eligible participants were those who volunteered to participate and provided written informed consent.
Exclusion Criteria
To ensure methodological standardization, the following cases were excluded:
Patients undergoing revision surgery.
Those undergoing unicompartmental (unicondylar) knee replacement, as the severity of surgical trauma differs from total replacement.
Bilateral cases, to prevent potential bias in assessing postoperative opioid consumption and pain scores.
Additionally, patients were excluded if:
The surgical duration exceeded 180 minutes.
There was a known history of coagulopathy, peripheral neuropathy, or allergy to local anesthetics.
The spinal anesthesia was insufficient, requiring a conversion to general anesthesia.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
