Custom Total Knee Replacement

Custom Total Knee Replacement 

In traditional knee replacement surgery, a surgeon would select an “off-the-shelf” implant from a range of standard fixed sizes, and then make the necessary adjustments to fit the implant to the patient during the procedure. Because off-the-shelf knee replacements aren’t designed to your specific anatomy, surgeons have to compromise on implant fit. This compromise may result in having implant overhang (implant hangs over the bone) or under hang (the implant is too small, leaving the bone exposed and uncovered). It could also result in an implant that isn’t aligned properly.

Customizable implants and instruments are designed based on a patient’s CT scan. An automated design process uses proprietary algorithms to map the surface of the joint in three dimensions. The software uses that information to design the implants and instrumentation that will match precisely to the 3D model of the knee, correcting the data for any underlying arthritic deformity such as bone spurs, cysts or flattening of the joint.
