Anatomical Total Knee System Provides Smoother Motion

The femoral component is designed with a single axis concept for articular stability, and with flexion for improved range of motion. The anterior flange shape and dimension provides optimal patella tracking, while the intercondylar cam design of the PS type is designed to prevent dislocation in deep flexion. The sphere-shaped articular surface design ensures reduced contact stress and improved stability.

A curved-on-curved tibial insert is designed to provide high conformity at the frontal plane to maximize contact area. Double radius at the sagittal plane ensures anterior stability and deep flexion, while the rotated articular track for both CR and PS versions allows optimal rotation of the femoral component. In the case of PS type, the tibial post is designed to reduce edge loading. The tibial insert also allows for improved anterior relief for deep flexion.

The tibial baseplate component for fixed-CR and Fixed-PS features a stem with a keel for improved initial implant stability; the stem has a posterior slope to avoid anterior cortex impingement. A precision ground finish on the baseplate allows full peripheral capture to reduce micromotion. The ground finish of the tibial baseplate insert-mating plane is designed for decreased backside wear. The patellar component dome is available in six sizes, with three fixation pegs that are uniform for all sizes. Cement pockets provide an optimal condition for cemented fixation. The Lospa Knee System is a product of Corentec (Seoul, South Korea), and has been approved by the US Food and Drug Administration (FDA).

“Surgeons have commented on the positive attributes of the Lospa Knee System, including the wide range of options allowing for patient variables, and in particular, surgeons have made affirmative comments as to the ease-of-use, and intuitiveness of our instrumentation,” said Michael Y. Son, vice president of Corentec America. “The Lospa Knee System is available with a robust catalog of instruments designed to ensure ease-of-use in the OR, and a more efficient surgical procedure.”
