5 Key Takeaways

• 1

  Kinematic alignment (KA) did not show significant differences in knee kinematics compared to mechanical alignment (MA) one year post-total knee arthroplasty.

• 2

  Patients with CPAK type 1 alignment showed smaller kinematic deviations from healthy controls with KA compared to MA, despite no significant direct kinematic differences.

• 3

  Mean Forgotten Joint Score (FJS) was higher in the KA group (65) than in the MA group (52) at one year, indicating better patient-reported outcomes with KA.

• 4

  Preoperative range of motion (ROM) positively correlated with postoperative FJS in the KA group, while a negative correlation was observed in the MA group.

• 5

  The study faced limitations including a smaller sample size due to COVID-19 and restricted eligibility, affecting the generalizability of the findings.
