To minimize the risk of patient dissatisfaction and implant failure, Prophecy® pre-operative navigation guides deliver more repeatedly accurate resections for optimal function and balanced loading to the prosthesis. This is essential because patient satisfaction and implant survivorship are directly linked to accurate alignment of the prosthetic components in total knee arthroplasty. Studies show the probability of revision surgery at fifteen years with accurate alignment is 4.7%.1-6 However, the rate drastically increases to 54% with malalignment.1-6 Prophecy® guides can make a measurable difference.


With normal knee kinematics and stability throughout the full range of motion, the Evolution® knee and Advance® knee better replace the natural stabilizing structures of the knee. They also prevent feelings of instability, which is the most common cause of TKA failures.1-6

Combined with the Prophecy® pre-operative navigation guides, both knee systems are distinctly capable of delivering successful knee replacements.


Replacing much of the standard instruments typically involved in establishing resections, Prophecy® guides conform to each patient’s individual anatomy. Through natural contours and osteophytes, Prophecy® guides are designed to fit precisely to the patient for optimal alignment, implant function, and longevity.

Competitive designs require resecting through nylon cutting slots, which can contaminate the joint with particulate debris. With built-in housings for metal cutting guides and pins, Prophecy® guides are fully compatible with standard instrumentation to provide precise, clean resections and even allow for recuts if necessary.


Reduced surgical steps

Up to twenty or more surgical steps required with standard instrumentation can be eliminated by using Prophecy® guides.

Reduced operative and turnover time

Operative and setup time can be greatly reduced by using more surgically efficient and reproducible Prophecy® guides instead of standard instrumentation.

No IM canal penetration

With alignment and rotation established virtually prior to surgery, Prophecy® cutting guides do not require intramedullary canal penetration. Standard instrumentation previously forced surgeons to drill into the intramedullary canal to establish correct alignment, which could potentially increase the risk of intraoperative complications.


Improved alignment

By aligning the knee pre-operatively using unobscured anatomic landmarks, Prophecy® guides improve accuracy and eliminate intraoperative bony landmark identification previously required to determine ideal femoral alignment and rotation.

Standard checks

To provide secondary checks for proper alignment and resections, Prophecy® guides are fully compatible with standard instrumentation unlike competitive designs.


- More consistent neutral mechanical axis alignment.

- Fewer +/- 3° outliers of the hip-knee-ankle line.

- No soft tissue impingement or issues with poor bone quality.
