Total Knee Joint Replacement Stability

In order to achieve joint stability, your physician is concerned with issues such as proper implant fit, range-of-motion/flexion, patella tracking, and joint articulation.

Implant Fit and Articulation

Fundamental to the design of the NexGen System is our belief that your physician should be empowered to create knee replacement solutions that are specific to your needs---as no cases are alike. The NexGen System, with a comprehensive offering of implant sizes, support devices, and surgical instrumentation, provides flexibility to deal with issues such as quality of bone stock and the condition/function of your muscles and ligaments. Improper fit of the joint component can result in poor articulation of the components, failure of the implant, and/or pain for the patient.
