Genicular Nerves Block, Total Knee Anthroplasty

Keywords
total knee arthroplasty, genicular block, postoperative pain
Brief summary
The aim of this study is to investigate the postoperative pain relieving effect of preoperative genicular block in total knee arthroplasty surgery. The main questions it aims to answer are: 1. Do visual analog scale (VAS) scores decrease in patients who underwent geniculate block? 2. Does opioid consumption decrease in patients who underwent geniculate block? Researchers will compare postoperative pain in patients who received genicular block with those who did not.One group of patients will be administered 0.25% bupivacaine with the geniculate block method. The other group will not undergo any intervention. Both groups will be administered intravenous morphine for postoperative analgesia.
Detailed description
Patients scheduled for knee arthroplasty will be randomly assigned into two groups. One group will receive a genicular nerve block prior to surgery , while the other group will not undergo any interventional procedure. The genicular nerve block will be administered in three quadrants around the knee, with each injection consisting of 5 mL of 0.25% Marcaine. All injections will be performed by investigator MA. Patient assessments will be conducted by investigator MO. Postoperative intravenous analgesia will be provided to both groups.
Interventions
DRUGGenicular blocks (bupivakain)
Genicular block is a regional analgesic technique performed with USG
DRUGPatient Control Analgesia (PCA) Morphine group
this group consists of the patients no any intervention preoperatively and they will be given morfin with PCA (Patient controlled analgesia) and paracetamol 3x1000 mg intravenous and diclofenac 75 mg intramuscular (if needed)
DRUGParacetamol (acetaminophen) + Diclofenac Sodium
All patients are given paracetamol (3x1000 mg) and diclofenac (if needed)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analog Scale Measure | 0-48 hours | VAS scores are assessed at 0th, 24th and 48th hours post operatively VAS score consists of 0-10 in numbers, the bigger the number the worse the pain |
| opioid consumption | 0-48 hours | Morphine consumption is assesed by PCA |
