NAPLES, Fla. (October 27, 2020) – The Zehr Center for Orthopaedics is expanding its non-surgical treatment of orthopaedic conditions to include regenerative medicine. Over the next several months, Robert J. Zehr, MD, will introduce stem cell therapy and exosome therapy programs into his Naples-based practice.

“I have been watching the science for years now and have come to appreciate the advancements made in the field of orthobiologics. I was the first surgeon in Southwest Florida to offer A-2-M therapy for knee osteoarthritis and have derived value from the plasma treatment in my own arthritic knee!” Dr. Zehr declares. “We are expanding our options to help a patient delay or avoid surgery all together, by employing naturally occurring biologics such as stem cell derivatives that may help patients heal their degenerative joints,” adds Dr. Zehr.

While he cautions that these therapies may not be successful, as standalone treatments, for everyone, Dr. Zehr explains that even traditional surgery patients can benefit, “The outcomes for surgery are highly contingent on the patient’s ability to heal and complete therapy. That ability can be leveraged in their favor by adding regenerative medicine products as a natural complement to their orthopaedic care.”

To further research the opportunities and develop the ZCO treatment program, Nikki Calvo, CST, has returned to the office as the Regenerative Therapy Coordinator. Calvo, a certified surgical technologist, has served alongside Dr. Zehr in the operating room for the past 10 years and will continue to assist him in surgery. In her new role, she will be the office liaison to the labs and manufacturers to coordinate patient data collection for research and improvement of care; direct the acquisition of the various stem cell derivatives; and arrange patients’ appointments in coordination with delivery of these time-sensitive biologics.

“We are thrilled to have Nikki back in the office. This position is a perfect fit, making the most of her in-depth medical knowledge, her experience in the OR, and her entrepreneurial spirit!” says Dr. Zehr. Calvo is currently pursuing her undergraduate degree at FGCU in the Business School of Entrepreneurship.
