AI Technical Summary
Conventional mechanical alignment approaches in total knee arthroplasty (TKA) fail to consider the natural kinematics of the knee, leading to issues such as altered gait patterns, increased ligament strain, improper load distribution, and patellofemoral complications, resulting in patient dissatisfaction and instability.
A tibial osteotomy system that guides tibial cutting based on kinematic alignment, using a trial member mounted to the distal femur and a cutting guide that replicates the natural kinematics of the knee, ensuring accurate bone cutting and alignment by considering the tension of medial and lateral collateral ligaments.
Improves patient satisfaction and ensures long-term implant stability by respecting the natural kinematics of the knee, reducing human error, and providing better surgical outcomes, especially for less experienced surgeons.
