Influence of Femoral Component Flexion on Outcomes After Primary Total Knee Arthroplasty.

ABSTRACT:

Background

Total knee arthroplasty (TKA) improves pain relief and function in end-stage arthritis. While coronal alignment has been well studied, the impact of femoral component flexion in the sagittal plane on outcomes remains underexplored. This study examines the effect of femoral component flexion on patellofemoral outcomes, using the Kujala anterior knee pain scale, and overall functional results after robotic-assisted TKA.

Methods

A retrospective review was conducted on 285 patients who underwent primary robotic-assisted TKA between January 2022 and January 2023. Femoral component flexion was classified as low (0°-2.5°), medium (2.6°-5.5°), and high (5.6°-8°). Outcomes were assessed preoperatively and 12 months postoperatively using the Kujala score, Oxford Knee Score
