The Ultrasonographic Measurement of Quadriceps Muscle Thickness and the Shape of the Femoral Nerve in Patients Undergoing Total Knee Arthroplasty: an Observational Study
- Conditions
- Total Knee Arthroplasty
- Registration Number
- NCT05382507
- Lead Sponsor
- Yonsei University
- Brief Summary
For each individual, the femoral nerve shows various shapes and locations. This is because the femoral nerve is located on top of the iliacus muscle, so the shape and location of the femoral nerve seems to be related to the patient's muscle mass. Ultrasound of the quadriceps femoris could represent a widely available, non-invasive, affordable, and reliable tool to evaluate skeletal muscle. We aim to investigate the relationship between muscle mass and the shape of the femoral nerve through this observational study.

- Primary Outcome Measures
Name Time Method the thickness of rectus femoralis and vastus intermedius, the shape of the femoral nerve preoperative (about 10 minutes before entering the operating room) Assessment of quadriceps femoris thickness using ultrasound. Thickness of each muscle is measured from the femur to the inner edge of the vastus intermedius (VI) muscle, or from subcutaneous tissue to the inner edge of the rectus femoris (RF) muscle. The shape of the femoral nerve was measured by ultrasound.
