ask the expertQ: I’ve been considering a total knee replacement for years. What’s the latest in technology and technique improvements?

A: Over the years, total knee replacement surgery has undergone many changes from the materials used in the prosthesis (the device that replaces the knee), to the instruments used, to the technology behind the whole process.

First discussions of knee replacement surgery took place as early as the late 1800s. Originally, ivory was considered for joint surface replacement. As knee replacement surgery progressed, different types of metals and plastics were developed and used. These have all been refined to what is currently being used which has minimal friction and minimal wear of the components with prolonged usage.

With the advancement of technology, the way total knee replacement surgery is approached has also changed. CT-guided imagery utilizes multiple X-ray measurements taken from different angles to allow us to see inside the knee without cutting. The availability of this technology has helped to perfect the alignment of the component placement. In recent years, improvements in CT-guided imagery have allowed us to give patients a more natural-feeling knee replacement.

With the development of three-dimensional printing combined with the CT-guided imagery, a total joint replacement prosthesis no longer needs to be based on an averaging of patient sizes and shapes. Rather, the total knee prosthesis is now customized for each individual patient. The iTotal Knee – which is produced by a company named Conformis – is customized for each individual patient based on data taken from a CT scan of their entire leg. This is the most natural prosthesis available. When made with this technology, the prosthesis mimics the natural shape of the individual’s knee. It is designed for optimal bone preservation. With it being as close as possible to the patient’s natural knee, it helps to increase one’s mobility and range of motion.

Currently this technology is being used at Bailey Medical Center by Dr. Jon Orjala with an excellent success rate. A total joint replacement program has been developed by a team of physical therapists and nurses along with Dr. Orjala to outline the process prior to surgery. Patients have expressed appreciation for the increased amount of information available.

Not everyone that has knee pain is in need of a knee replacement. However, for those who are at that point in their life, they aren’t limited to major hospitals in big cities. Dr. Orjala has an extensive history of total knee replacements with an excellent track record of success.
