U2™ Knee System
The Spirit of U2 Knee - Preciseness, Safety and Durability The intercondylar removal volume of U2 PS knee is as low as 5.7 cm3
(size 6). The 30% reduced volume and the narrow 18 mm intercondylar
width preserve the bone stock. This design also prevents from the
periprosthetic distal condyle fracture.
prepare the precise box space, the intercondylar notch is made by
reaming instead of cutting. The stopper on the reamer minimizes the risk
of tibial damage.
knee achieves 155° ROM with resection thickness of 9 mm in distal and
posterior condyles. The ROM fulfills daily activities of patients with
high standard of motion safety.
Enhanced Axial Rotation
matched “round to round” spine and box contact mechanism avoids corner
impingement while rotating. The ±12.5° I / E rotation conforms to the
Jumping Distance Safety
A refined spine and cam mechanism minimizes the risk of dislocation at maximum ROM.
PS Notch Width Consistency
The consistent 18 mm intercondylar width provides full interchangeability between femoral and tibial sizes.
Tibial Insert Design
The built-in 5° posterior slope of the insert enhances the ROM and restores the natural morphology of tibial plateau.
