Accuracy of Sagittal Plane Component Alignment in Robotic-Assisted Total Knee Arthroplasty.

ABSTRACT:

Background

Robotic-assisted total knee arthroplasty (rTKA) is utilized to facilitate accurate and precise resection goals. Most literature has focused on postoperative limb and component alignment in the coronal plane. This study sought to evaluate the accuracy of 2 robotic systems in executing sagittal plane resections during rTKA.

Methods

This retrospective review analyzed 169 consecutive primary rTKAs at a single institution from January 2023 to January 2024. Surgeries were performed by two fellowship-trained arthroplasty surgeons, each using a different rTKA system (73 System 1 and 96 System 2). Femoral and tibial component sagittal alignment were measured on postoperative and compared to intraoperative plans.

Results

Both systems more frequently resulted in reduc
