    Mechanical alignment (MA) remains the preferred method for total knee arthroplasty, achieving good survival rates but leaving some patients dissatisfied.

  • 2

    New alignment strategies like phenotype alignment and kinematic alignment aim to restore pre-arthritic knee kinematics for improved functional outcomes.

  • 3

    A simulation study assessed how coronal limb alignment affects bone cuts in neutral knee phenotypes, emphasizing the need for personalized approaches.

  • 4

    The study identified that one alignment strategy does not fit all, particularly highlighting the variability in knee phenotypes among patients.

  • 5

    Four common neutral knee phenotypes were analyzed, revealing significant differences in joint line obliquities and their implications for surgical alignment.
