PROPHECY® GAP BALANCING SYSTEM

Home Healthcare Professionals - Our Products Orthopedics Knee Prophecy® Personalized Knee Solutions Prophecy® Gap Balancing System

To provide the surgeon with a more accurate simulation of optimum final implant placement and correction of joint imbalance before any femoral resections are performed, the Prophecy® gap balancing system offers balancing-oriented devices and tensioners that overcome potential limitations of standard instrumentation. The value of this superior gap balancing is illustrated by literature that shows nearly half of all knee revisions can be attributed to a cause that can be prevented with correct gap balancing.1-3

ONE-CUT SIMULATION

With only a tibial resection, the Prophecy® gap balancing system is able to simulate the final prosthesis position and alignment, with ligament correction, prior to any femoral resections being performed.

FLEXION AND EXTENSION GAP BALANCING

With the patella reduced for anatomic tibiofemoral gap assessments, Prophecy® guides and instrumentation allow for full extension and 90 degrees of flexion balancing.

AXIAL AND ROTATIONAL ADJUSTMENTS

The femoral Prophecy® guide allows for the use of anterior and distal pin guides to account for joint gap corrections that may necessitate axial and rotational adjustments.
