Shelton Orthopedics Offers ConforMIS Personalized Knee Replacement

A revolutionary knee implant system is now available, locally! MGH Shelton Orthopedics now offers ConforMIS – a knee replacement system designed to conform precisely to your own, unique anatomy. And the entire process – from your pre-op diagnostic imaging to your post-op physical therapy – is done right here at Mason General Hospital.

Using a series of CT scans of your knee, a computer-generated virtual model is created to build your own, personalized knee implant designed to provide a precise fit and correct alignment. The virtual “blueprint” is electronically sent to ConforMIS, where the custom implant is manufactured in approximately six weeks, and then delivered to your local surgeon in time for your scheduled surgery.

Dr. Davis specializes in knee replacement at MGH Shelton Orthopedics, and highly endorses this new technology for his patients who are good candidates for the procedure. “We’re pleased to be able to offer the ConforMIS system to our patients who suffer with the pain of osteoarthritis or a knee injury,” said Dr. Davis. “The goal is always to find the right solution for each patient, and ConforMIS allows us to tailor a fit that will do that.”

MGH Shelton Orthopedics is seeing great patient outcomes with the ConforMIS knee replacement system since it began implementing it early this year. Ruth Benson, a 64 year-old Shelton resident who underwent a partial knee replacement in February, is now pain-free. “I wish I could have had the ConforMIS procedure on my other knee that was done the year before,” she said.

In May, Dr. Davis performed two more surgeries with the ConforMIS knee replacement system. Hilda Mayes, 68, of Matlock had her entire left knee replaced, is also free of pain, and anxious to have the same procedure on her right knee in the future. “Dr. Davis did a marvelous job!” she exclaimed. “I was back to normal activity in just a few weeks, and right now I’m walking about half a mile a day,” she said, adding, “– but I know I can go even further.”

Georgette Bellack, 51, of Elma, had a partial ‘outer’ knee replacement and is now almost pain-free. “Dr. Davis and his team are amazing,” she said, describing the great care she received at MGH. “They make you feel like they’ve known you forever!”
