Immediate Postoperative Ultrasound Assessment of Quadriceps Muscle and Femoral Nerve Morphology After Total Knee Arthroplasty: A Methodological Feasibility Study

This exploratory case series demonstrates the feasibility of early postoperative ultrasound assessment of quadriceps muscle and femoral nerve morphology following conventional and robot-assisted TKA. These descriptive findings provide preliminary data and a methodological basis for future longitudinal studies integrating functional and clinical outcomes.
