The difference is in the design.

Evolution® Medial-Pivot Knee solves patients knee problems.
Prior to the launch of Medial-Pivot, nearly 20% of all patients globally were unhappy with their knee replacement due to residual pain, functional issues and early implant failure[1].

The original Medial- Pivot knee.

The first Medial-Pivot Knee was first launched in 1998, A culmination of years of research and design by Wright Medical and Dr. J. David Blaha resulted in a truly unique knee replacement design.

Knee-deep in innovation:
Top 10 reasons top surgeons are choosing Evolution® Medial-Pivot Knee

1.

PATELLA FRIENDLY

Designed to optimise patella tracking
Anatomic patella-friendly constant radius femoral components outperform other types of implants in reducing anterior knee pain and patella-femoral joint complications in TKA, even when the patellae are left un-resurfaced.

2.

SATISFACTION

95% Satisfaction with the medial-pivot knee[1]
Patient reported satisfaction with a Medial-Pivot prosthesis is 95%[1]. A recent study also confirmed higher patient satisfaction when knees are balanced with a tighter medial compartment.

3.

BONE CONSERVING

No need to resect a box
Anatomic patella-friendly constant radius femoral components outperform other types of implants in reducing anterior knee pain and patella-femoral joint complications in TKA, even when the patellae are left un-resurfaced.

4.

STABILITY

Maximises stability throughout the range of motion
Patient reported satisfaction with a Medial-Pivot prosthesis is 95%. A recent study also confirmed higher patient satisfaction when knees are balanced with a tighter medial compartment.

5.

SURVIVORSHIP

98.8% Survivorship at 17 Years[2]

PATIENT PREFERRED[3]

Patients feel the difference
Patient reported satisfaction with a Medial-Pivot prosthesis is 95%. A recent study also confirmed higher patient satisfaction when knees are balanced with a tighter medial compartment.

7.

NATURAL KINEMATICS

Designed to promote natural kinematics
Anatomic patella-friendly constant radius femoral components outperform other types of implants in reducing anterior knee pain and patella-femoral joint complications in TKA, even when the patellae are left un-resurfaced.

8.

FORGOTTEN JOINT

Higher forgotten knee score than traditional knee systems[4]
Patient reported satisfaction with a Medial-Pivot prosthesis is 95%. A recent study also confirmed higher patient satisfaction when knees are balanced with a tighter medial compartment.

9.

ANATOMIC GAP BALANCING

Restore the natural asymmetric balance of MCL & LCL
Anatomic patella-friendly constant radius femoral components outperform other types of implants in reducing anterior knee pain and patella-femoral joint complications in TKA, even when the patellae are left un-resurfaced.

10.

RANGE OF MOTION

More natural knee movement
Patient reported satisfaction with a Medial-Pivot prosthesis is 95%. A recent study also confirmed higher patient satisfaction when knees are balanced with a tighter medial compartment.

Patients can feel the difference in stability.

A bilateral patient preference study sought to examine if patients have higher satisfaction with one prosthesis over another[1].
  • 440 patients underwent bilateral TKA using a different prosthesis on each side.
  • Five knee prostheses were used:
    ACL-PCL Retaining, Posterior Cruciate-Retaining (CR),
    Medial-Pivot (MP), Mobile-Bearing (MB) and Posterior-Stabilized (PS).
  • The study found patients who underwent bilateral staged TKA were more likely to prefer retention of the ACL and PCL or substitution with the MP Prosthesis.
