Femoral component rotational alignment in robotic-assisted total knee arthroplasty with functional knee positioning varies across knee phenotypes without affecting clinical outcomes.

ABSTRACT:

Purpose

This retrospective, observational study aimed to investigate the distribution of femoral component rotational alignment among different knee phenotypes and assess the clinical relevance of femoral component rotation variability in patients undergoing image-based robotic-assisted total knee arthroplasty (RA-TKA) performed with functional knee positioning (FP). It was hypothesized that femoral component rotational alignment can change based on preoperative knee phenotypes, without affecting clinical outcomes.

Methods

A total of 256 patients who underwent image-based RA-TKA with the Mako robotic system at a single centre from February 2020 to March 2022 were included. Preoperative robotic-derived computed tomography (CT) data were gathered to determine the Coronal Plane
