U2 MB™

PTG mobile-bearing posterior stabilised

The U2 Knee™ System, designed by the United Orthopedic, is a complete range of 1st line treatment PTGs: Fixed and mobile CR, fixed and mobile PS and PSA revision with constrained insert.

The fixed tibial baseplate is commonly used in fixed cruciate-retaining (U2 CMA™) and posterior stabilised (U2 PS™) fixed inserts.

The mobile tibial baseplate is commonly used in cruciate-retaining (U2 MBC™) and posterior stabilised (U2 MB™) mobile inserts

Description

The PTG U2 MB™ is a posterior stabilised rotating femoral prosthesis with a fixed PS insert.

The posterior stabilised femur has a multi-radius design with a “patella friendly” trochlear groove that promotes flexion and stability.
