About Custom Fit Total Knee Replacement Surgery

Custom Fit Total Knee Replacement Surgery is the newest technology in total knee replacement. The process starts several weeks before your surgery with a MRI scan. The MRI makes precise measurements of your knee. Computer software at the OtisMed Company transforms that MRI image into a 3-D model of your arthritic knee and then virtually corrects any deformity to return the knee to its pre-arthritic state. A computerized 3-D image of the implant to be used at the time of surgery is then Shape-Matched™ to the anatomically correct knee model. This helps determine the correct implant size and placement based on that patient’s normal knee alignment.

Using all this information, a set of custom cutting guides is then created for use during your individual surgery. Each knee is unique and each set of MRI computer matched custom surgical guides is one of a kind.

From his suburban Philadelphia orthopaedic practice, Dr. Joseph Vernace was the first east coast surgeon to perform this surgery and is one of a handful of U.S. surgeons who currently does custom fit total knee replacement surgeries.

Surgeons who do custom fit total knee replacement say that it results in more predictable results. Patients are reporting faster recovery times and greater satisfaction with their replacement knees.

CFTK replacement patients’ average Knee Society Scores (a standard clinical evaluation system for reporting Total Knee Replacement patients’ results) are more than 20% higher at 3 months post surgery than most previous studies of conventional knee replacement or intraoperative computer assisted total knee scores at 6 months post surgery.

This means better function and stability and less pain sooner after surgery.
