The rotating-platform design permits motion between the femoral-polyethylene insert (articular surface) and polyethylene insert-tibial articulating surfaces (undersurface).

We report now a potential hindrance to the reduction of the articular surface that we have termed, the “trap door” effect. Clamp the lateral fragment ...

Fractures of the posterior articular surface of the tibia require ORIF when more than 25% of the articular surface is involved, since, at about that point, the posterior aspect of the tibial ...

Lospa knee system has improved joint performance and stability due to the same features offered by the modular tibial insert. Enhanced resistance ofdeformation and wear, by maintaining the PE ...
