About this study
Official title: Comparison of the Effects of Femoral Nerve Block and Adductor Canal Block on Postoperative Analgesia in Patients Undergoing Unilateral Total Knee Arthroplasty
The frequency of femoral nerve block and adductor canal block for analgesia after TKA(total knee arthroplasty) increases with the use of ultrasonography in regional anesthesia. In this study, we aimed to compare the effects of femoral nerve block and adductor canal block on postoperative analgesia in patients undergoing unilateral knee arthroplasty.

What is being measured
The primary outcome is the main question the study is designed to answer.
Tramadol consumption
Postoperative tramadol consumption with patient controlled analgesia
Measured: 24 hours after operation

VAS(visual analogue scale) score (0-10, 0 is no pain, 10 is the most severe pain) is less than four is adequate analgesia
Measured: 24 hours after operation
Rescue analgesic requirement
If VAS(visual analogue scale) score (0-10, 0 is no pain, 10 is the most severe pain) is is four or more, paracetamol 1000 mg is administered
Measured: 24 hours after operation
Secondary outcomes (1)
Postoperative nausea and vomiting
Frequency of postoperative nausea and vomiting

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Bupivacaine Injection in people with Knee Replacement, Total and Pain, Postoperative, run by Sisli Hamidiye Etfal Training and Research Hospital at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Tramadol consumption (time frame: 24 hours after operation). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
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 13 Mar 2020.
