According to recent article in the Boston Business Journal, a technological innovation will allow partial and total knee replacement surgeries to be performed by a robotic arm. The company claims that this robotic arm sets them apart form companies such as Stryker, DePuy, and Zimmer. As your Boston knee replacement lawyer can explain, there have been many products liability lawsuits filed against the makers of these knees for issues involving defective design and a failure to adequately warn patients of known dangers.
The robotic arm is intended to be used by surgeons to allow for a more precise alignment of the artificial knee components. This company is claiming that proper alignment is the difference between success and failure in a knee replacement procedure.
The new device uses a 3D image of the knee and uses the image to saw off the knee joint at the proper place and at the proper angle. Without the use of the new robotic arm, surgeons use a metal guide and attempt to come within a few degrees of perfect alignment. The company also claims that if alignment is not proper, it can lead to a total failure in the replacement knee, and the patient will require another operation and another artificial knee to replace the failed one. Surgeons typically get the alignment right 75 percent of the time, and this robotic arm is supposedly able to get an exact alignment over 90 percent of the time.
