Lospa Knee® System Features Shape for a Cruciate Retaining (CR) to a Posterior Stabilized (PS) Knee Within a Single System

Corentec America, Inc.

“Corentec America has successfully completed a number of cases in the U.S. using the Lospa Knee System,” said Michael Y. Son, vice president, Corentec America, Inc. “The feedback from leading surgeons has been outstanding, exactly as we expected."

Corentec America, Inc., a wholly-owned subsidiary of Seoul-based Corentec Co., Ltd., has announced that the Company has received FDA clearance to market the its novel Lospa Knee System® in the United States. The innovative Knee Joint Replacement System is available now, along with the currently available Total Hip Replacement System, and a Pedicle Screw System for spine. Product extensions for the Company’s already cleared Bencox THR® System and Spinal Implants are in the process of FDA clearance, or in the development pipeline for the U.S. market.

“Corentec America has successfully completed a number of cases in the U.S. using the Lospa Knee System,” said Michael Y. Son, vice president, Corentec America, Inc. “The feedback from leading surgeons has been outstanding, exactly as we expected. 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.” Mr. Son added, “Corentec is now poised to enter the next roll-out phase for the Lospa Knee System by reaching more distributors and surgeons.” 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.”

State of the Art Design

Manufactured in state-of-the-art facilities located in South Korea, the Lospa Knee System offers an anatomically featured shape for both a cruciate retaining (CR) and a posterior stabilized (PS) knee within a single system. This ensures successful patient outcomes with natural knee range of motion and increased longevity of the implant.

Femoral Component

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

Tibial Insert (Fixed Type)

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. The Rotated articular track for 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.

Tibial Baseplate

The Tibial Baseplate, 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 Tibial Baseplate allows for full peripheral capture to reduce micromotion. The ground finish of the Tibial Baseplate insert mating plane is designed for decreased backside wear.

Patellar Component

The 30mm Patellar Component Dome is available in six sizes (26mm, 28mm, 30mm, 32mm, 34mm, and 36mm). Three fixation pegs are uniform for all sizes. Cement pockets provide an optimal condition for cemented fixation. The cement pocket is 1mm in depth, but is not deep enough to compromise the strength of the component. There is reinforcement in the center of the pocket and peripheral rim, also with a 1mm thickness.

Size Combinations

Corentec offers six Tibial inset sizes (Fixed Bearing Couple), in combination with 16 Femoral component sizes. There are six CR Type, and six PS Fixed Type size combinations. For additional information, visit
