SALINE: Doctor performs less invasive knee replacement

A Saline doctor is now performing a procedure that aims to help patients with arthritis, a condition that affects approximately 50 million adults in the U.S., according to the U.S. Center for Disease Control.

By 2030, that number is expected to reach an estimated 67 million.

In October, Dr. Mark Kelley, an orthopedic surgeon at St. Joseph Mercy Saline Hospital began performing custom partial knee replacements that are less invasive and reduce the time it takes to heal.

After other types of treatment fail, a patient may require an implant in order to receive relief from the pain associated with the condition.

“It’s a much easier recovery,” said Kelley, who has performed nearly 20 of the procedures on patients with osteoarthritis, the most common type.

Doctors are also performing the procedure in Novi, Troy and Battle Creek.

Kelley uses implants made by ConforMis, the Burlington, Mass.-based company that manufactures customized implants used in knee and hip replacements.

Using “image to implant” technology, data from a CT scan helps create the personalized implant that conforms to the knee. Each device also comes with specialized tools to help the surgeon place the implant.

Standard implants come in certain sizes and shapes, requiring surgeons to cut the bone to fit it to the joint. With the personalized implant, the surgeon does not need to cut as much bone because it is custom made for the patient’s knee.

“We get pretty dramatic improvements and we are really not removing a lot of bone,” he said. Continued...

Kelley said patients come to his office with knee pain for a variety of reasons including trauma, surgery, wear and tear and family history.

Through use of an x-ray, it is decided whether the patient would be a good candidate for the surgery. A few of several qualifying factors include the amount of arthritis and age.

“It’s a more viable option for younger patients as it is a much easier recovery time,” he said.

Kelley performs the surgery as an outpatient procedure. Patients manage their pain through pills, rather than intravenous medications that are used during a total knee replacement, where the patient typically stays two days in the hospital.

After surgery, the patient begins physical therapy and requires crutches for anywhere from 10 days to two weeks.

If in the future the patient required a total-knee replacement, the procedure would be easier because more bone is available, he said.

Minimally invasive procedures have been gaining popularity in the past several years, making it easier for a patient to return to work after a procedure that would have required an extensive hospital stay.

Kelley said he is encouraged that other doctors will begin using the procedure as well.

“I think other people will definitely catch onto it,” he said. “Someone had to do it first.”
