Does Restoration of Constitutional Alignment Improve Outcomes in Total Knee Arthroplasty?

ABSTRACT:

Background

While neutral mechanical alignment has been the gold standard for total knee arthroplasty (TKA), constitutional knee alignment is commonly nonneutral and varies widely among individuals. We aimed to determine if a bounded functional alignment strategy in robotic assisted TKA restored constitutional alignment and if this restoration resulted in superior patient-reported outcomes (PROs).

Methods

We retrospectively reviewed patients who underwent robotic TKA with a bounded functional alignment strategy at a single institution. Final intraoperative knee alignment was compared to calculated constitutional alignment, which was unknown to the surgeons during the procedure.
