1 Luminus Flex Total Knee System (Fixed Type) The Innovative Technology for Knee Replacement

2 Intro The Luminus-Flex Total Knee system takes its name from the English word "Luminous" An adjective meaning radiating, shining or illuminating to describe the Gold Tin Ceramic coating. In combination with the latin root word "Flexus", meaning to bend, emphasises the full range of motion and smooth bending provided with the system. Advantages of L-F Total Knee System Deeper and wider proximal trochlear groove for the optimal patella tracking and more generous movement in both hyperflexion and rotation. Lengthened trochlear groove having shorter notch height supports the patella and quadriceps tendon in hyperflexion. Multi-axis design of femoral component with 9.5mm and 9mm of posterior and distal condyles thickness, allows minimum bone resection and enhancement in range of motion up to 150. Lengthened width of posterior condyles and unique posterior cam design assure a safe jump distance which reduces the risk of dislocation and contact stress on tibial insert in hyperflexion. Reduction in weight and risk for metal allergy by using titanium material, and enhancement in gravimetric wear rate on tibial insert and backside wear by applying Ceramic Titanium Nitride(TiN) coating. Deeper patella tendon relief minimizes the contract stress and patella impingement in hyperflexion. 3 of posterior Tibia Base Plate allowing hyperflexion for initial implant stability and reduction of the risk of anterior cortex impingement. 02

3 Advanced Bio-compatible Technology Weight Reduction in Titanium and TiN-Coating and Sanding Surface Treatments Titanium is used for Reduction of weight up to 50% compared to the weight of Total Knee Replacement system made by Co-Cr. The weight of L-F Femroal Component is similar to the bone resection weight that is removed from a patient during surgery. Moreover, unlike Co- Cr material there is no risk of metal allergy in titanium Nitride(TiN) coating and it provides better wear rate with UHMWPE Tibial Insert. In addition, the sanding surface treatment was applied to the inner surface of femoral component to provide better adhesion and integration with bone and cement material.

4 Luminus Flex Total Knee System (Fixed Type) Advanced Bio-compatible Technology L-F Femoral Component Lengthened Width of Posterior Condyles Enhancement in Posterior Cam Design Wider Proximal Trochlear Groove Deeper Trochlear Groove Longer Proximal Trochlear Groove Multi-axis for Bionic Profile Optimization in Tibia-Femoral Articulation 04

5 Deeper Trochlear Groove and Anterior Flange Geometry L-F Femoral Component has anterior flange shape for the optimal patella tracking and performance. This unique geometry supports more generous patella movement during both flexion and rotation. Reduction of Notch Height and Longer Trochlear Groove L-F Femoral Component (Size 3) 35mm (58.3%) L-F Femoral Component has a shorter notch height leading to lengthened trochlear groove to support the patella and quadriceps tendon in hyperflexion. Fixed Type 05

6 Luminus Flex Total Knee System (Fixed Type) Wider Proximal Trochlear Groove 0 ~15 L-F Femoral Component provides balance in patella performance through a widened trochelar floor to reduce constraining forces and shear stresses in extension. These features provide excellent patellar tracking regardless of the patient's Q-angle. Sagittal Geometry Features with Multi-axis for Bionic Profile L-F Femoral Component has multi-axis design concept to accomodate bionic profile for articular stability and smoothness with flexion and enhancement in range of motion. The thickness of the posterior and distal condyles are 9.5mm and 9mm, respectively and the anterior flange angle is 4 degrees. These allow for less femoral bone resection. 06

7 Coronal Geometry Features L-F Femoral Component has fully congruent, spherical shaped, articular surface to reduce contact stress with tibial insert and to improve stability in physiological motion. The profile of lengthened width of posterior condyles provides increased contact area. Increased Range of Motion (150 ) L-F Femoral Component has increased posterior condyle thickness design to allow and oblige for patients to have up to 150 degrees of hyperflexion without the need of additional posterior condyles resection and patella impingement. Fixed Type 07

8 Luminus Flex Total Knee System (Fixed Type) Proportional of Femoral Component Sizes L-F Femoral Component posterior condyles size increases arithmetically with 2.5mm difference in size and this provides implant interchangeability within 2 sizes and better bone coverage. Enhancement in Posterior Cam Design L-F Femoral Component has intercondylar and unique posterior cam design of posterior stabilized total knee replacement to reduce the risk of dislocation and contact stress with tibial insert in Hyperflexion. 08

13 Sagittal and Coronal Geometry Features 3 35/40mm L-F Tibial Baseplate has a stem with keel which has 3 degrees of posterior slope for enhanced initial implant stability and reduced anterior cortex impingement. It also provides the potential for deep flexion. Length of stem and thinckness of plate are 35mm and 6.5mm respectively. Prosthesis Strength Verification using Fatigue Testing Experiment Fatigue testings of tibial baseplates were performed with frequency of 10Hz at 10.0 million cycles in ambient air conditions. All products successfully completed 10 million cycles and showed no indications of fracture or failure. Moreover, there was no backside wear or any defeat due to Tin Coating. Fixed Type 13
