Innovative Device May Prevent the Need for Knee Replacement

Innovative Device May Prevent the Need for Knee Replacement

More than 4.7 million Americans are living with a knee replacement, according to a Mayo Clinic study. And more than 30 million American adults are living with osteoarthritis.

There’s no cure for osteoarthritis, but treatment ranges from conservative options like physical therapy to invasive ones such as such as knee replacement.

Americans with knee osteoarthritis may soon have a less invasive option than knee replacement to relieve pain. Surgeons at Ohio State University Medical Center performed the first surgery in the U.S. to implant a device designed to slow the progression of the disease and extend the life of the original joint.

The new device, called the Calypso Knee System, aims to strike a balance between the two. The device works by providing support outside the knee joint without altering the anatomy of the knee itself. 

Dr. David Flanigan is the orthopedic surgeon who performed the first surgery in December 2018. He said the device is basically a shock absorber that takes pressure off the inside of the knee. It creates a cushion similar to what cartilage provides inside a healthy joint.

“If we can have a device that can be close to the joint, allowing it to offload it but then maintain everything else that’s in the joint that may be a good benefit for the patient,” Dr. Flanigan said.

If the trial is successful, Dr. Flanigan said he expects the procedure will soon become available to patients across the country.

For those considering knee replacement surgery, stay up to date on the development of this device. For more information on Moximed's Calypso Knee System, visit their website at
