Total Knee Arthroplasty
Conditions
Keywords
a continuous proximal adductor canal block (ACB), continuous femoral nerve block (FNB)
Brief summary
The purpose of the study is to compare continuous femoral nerve block with continuous proximal adductor canal block for postoperative pain control and rehabilitation.
Detailed description
Patients meeting the criteria: American Society of Anesthesiologists (ASA) class I and II, that are scheduled for elective total knee arthroplasty, will be recruited into the study. Subjects will be randomized into 2 groups: those who will receive a continuous proximal adductor canal block (ACB) and those who will receive a continuous femoral nerve block (FNB).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Motor effects | 24 hours (postoperatively) | Subjects' change in motor effects will be assessed as maximum voluntary isometric contraction (MVIC) in the quadriceps muscle. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pain score | On average between 6 and 8 hours postoperatively | Subjects' pain will be assessed using a numerical pain score, where 10 is the greatest amount of pain. |
| Opioid consumption | On average between 6 and 8 hours postoperatively | Subjects' pain will be assessed by tracking opioid consumption postoperatively. |
| Motor effects | On average between 6 and 8 hours postoperatively | Subjects' change in motor effects will be assessed as maximum voluntary isometric contraction (MVIC) in the quadriceps muscle. |
