degenerative joint disease (including osteoarthritis, traumatic arthritis, or avascular

necrosis), rheumatoid arthritis or post-traumatic arthritis .

• Post-traumatic loss of knee joint configuration and function .

• Moderate varus, valgus, or flexion deformity in which the ligamentous structures

can be returned to adequate function and stability .

• Revision of previous unsuccessful knee replacement or other procedure .

• Fracture of the distal femur and/or proximal tibia that cannot be stabilized by

standard fracture management techniques .

Additional Indications for Posterior Stabilized (PS) Components:

• Ligamentous instability requiring implant bearing surface geometries with

increased constraint .

• Absent or non-functioning posterior cruciate ligament .

• Severe anteroposterior instability of the knee joint .

The Triathlon Total Knee System beaded and beaded with Peri-Apatite components

are intended for uncemented use only .

The Triathlon Tritanium Tibial Baseplate and Tritanium Metal-Backed Patella
