About this study
Official title: Comparison of Epidural Analgesia With Intra-Articular Infiltration Analgesia for Postoperative Total Knee Arthroplasty Analgesia: A Prospective, Randomized Controlled Trial
The results of combining infiltrative analgesia applied by orthopedists with epidural analgesia applied by anesthesiologists after knee replacement surgery will be compared.
It aims to compare epidural analgesia with the maximum reduction of postoperative pain in patients, as well as in terms of both analgesic and complications.
The study will include patients who have undergone knee replacement surgery for six months. In the study, we will compare the results of painkillers applied to the patient from the waist or knee after the waist numbing anesthesia, which includes some of the routinely applied protocols of your knee replacement surgery. It is a condition that will be monitored after surgery. The study aims to reduce maximum pain with two painkiller methods applied in small amounts or together. No interventional application will be made to the patient who will undergo surgery other than routine application. After the surgery, you will be asked verbally about your pain level and side effects at certain hours after the surgery and the amount of painkillers used and the amount of painkillers will be determined according to the follow-up hours (1st, 2nd, 6th, 12th, 24th and 48th hours after the surgery). In addition to these, complications will also be monitored. The results of patients who can be fully followed up at the end of 6 months will be presented as a scientific study.

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06872528, which also lists 2 linked publications.
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.
