Both osseous defects and soft tissue dysfunctions can be treated with Columbus Revision.

Functional description

The AS Columbus REV F Tibia is a fixed bearing tibial component made from CoCrMo with a multi-layer CrN-CrCN-ZrN coating, which prevents the release of metal ions. The device is compatible with all Columbus Revision Gliding Surfaces with the option for stem extensions and spacers to compensate for bone defects. A mechanism is integrated in the REV F tibia plateau to provide +/- 4mm for size 0 and for the other sizes +/- 6mm medial/lateral off-set of the attachable tibia stems.
