LEGION™
Total Knee System
View list of all products
The LEGION◊ Total Knee System empowers you to address diverse surgical challenges with one A-P Resection, one system and one company such as:
-
Rheumatoid arthritis
-
Post-traumatic arthritis
-
Osteoarthritis
-
Degenerative arthritis in older patients whose age, weight and activity level are compatible with an adequate long-term result
-
Failed osteotomies
-
Unicompartmental replacement or total knee replacement
-
Patients in primary and revision surgery, where the anterior and posterior cruciate ligaments are incompetent and the collateral ligaments remain intact.
- Patients in primary and revision surgery, where the posterior cruciate ligament and one or both of the collateral ligaments (i.e. medical collateral and/or lateral collateral ligament) are absent or incompetent.
All LEGION◊ Femoral Components share the following features:
- OXINIUM◊ material and CoCr options
- Anatomic design
- Lateralized trochlear groove
- Common A-P Resection
| The LEGION◊ Revision Knees offer a larger selection of components, offsets, augments and stems. |

Minimized Bone Resection
The LEGION◊ constrained femoral components were designed with varying anterior chamfer angles to minimize bone resection and maximize the deepened patellar groove. The cam on the constrained femoral component has been positioned closer to the distal surface and more posteriorly resulting in a smaller box requiring less bone removal.
Stronger, Shorter Female Taper
Designed and sized to provide increased strength, the new female taper allows for a larger selection of stem sizes. The new taper has a shorter post compared to the GENESIS◊ II Total Knee System which allows surgeons a better metaphyseal offset fit. The taper also includes a secondary locking mechanism for postoperative security.
Proper Kinematics
The deepened and extended trochlear groove of the LEGION◊ constrained femoral component is the same lateralized design as the LEGION◊ CR and PS – which allows for added patellofemoral contact area and greater subluxation resistance.
Posterior condyles are tightly radiused to maximize flexion. |

- Be cause your patients come in different sizes, symmetrical shape provides better tibial coverage; medalized stem aligns with the center of the canal
- Proven locking mechanism with anterior and posterior dovetail
- Highly polished baseplate to reduce backside wear
