Today, according to the latest literature, nearly 20% of all patients are unhappy with their total knee replacement due to residual pain, functional issues and early implant failure.
The eMP™ Knee System is designed to answer the limitations of traditional implants by delivering superior flexion stability, anatomic motion, and wear –limiting design characteristics.
The Medial-Pivot Knee is uniquely engineered to reproduce a healthy knee’s stability and motion. With a stable, pivoting medial side and a lateral side that rolls forward or backward throughout flexion, the eMP Knee System is designed to feel and function like a natural knee.
The Medial-Pivot Knee features a highly conforming medial side that results from a constant radius design. Reproducing the natural function and stability of the ACL and PCL, this design is unique from every other less conforming traditional knee system. It gives the Medial-Pivot Knee natural motion, so it feels more like a normal knee.
Better Quad Force.
With a more normal quadriceps force pattern, patients not only enjoy improved functionality but also more natural feeling. By reducing quadriceps avoidance, the highly conforming design of the eMP™ System enhances quadriceps efficiency and reduces problems common in traditional knee replacements. This can actually increase patient proprioception or awareness of the knee’s position, and uniquely create a more normal, natural feeling.
Single Radius Design.
To achieve postoperative satisfaction, patients want their implant to deliver high functionality and a more natural feeling. The single-radius design of the eMP™ Knee System provides stability through all phases of flexion. AP translation is also decreased to help achieve a more normal feel. This represents a dramatic advance over traditional knee replacements, which have been shown to exhibit anterior-posterior translation that can decrease stability and cause early revisions.
High Conforming Articulations.
Stable Range of Motion.
It is routine for patients to complain of instability following a traditional knee replacement. Studies also clearly show instability to be the leading cause of early revisions.3-5 By delivering a more secure, highly conforming articulation, the eMP™ Knee System provides the kind of stability throughout the range of motion that patients seek.
Greater Clinical Functionality.
With a constant radius design, the eMP™ Knee System gives patients a more stable feeling and more normal biomechanics. The constant radius in both the coronal and sagittal planes is uniquely designed to mimic the movement of the natural knee. This is a significant benefit over traditional multi-radius implants, which are typically less stable and fail to deliver the same natural feeling to the patient.
With a constant radius femoral component featuring a highly congruent tibial insert, the eMP™ Knee System also delivers superior stability in mid-flexion and prevents anterior-posterior translation. The simple result is that the eMP™ constant radius knee design has been documented in literature to achieve higher clinical function than competitive multi-radius designs.
Reduce Quadriceps Avoidance.
Prevent Altered Gait.
Achieve Normal Feeling.
On the heels of a knee replacement, patients often suffer from changes to muscle contribution to such extent that it alters their gait. Center-of-mass acceleration can also be affected. To compensate, patients typically lean forward and use their hamstrings over their quads, which produces a common “quadriceps avoidance” gait.7
The innovative design of the eMP™ Knee System delivers a more normal quadriceps force pattern. The result is a positive effect on knee function. It delivers enhanced quadriceps efficiency and reduces the quadriceps avoidance found in traditional knee replacements, so patients can enjoy increased proprioception and more normal feeling.
