A local stem cell study is changing the future of orthopedics.

A new study taking place at the Andrews Institute in Northwest Florida could shape the future of orthopedic surgery.

The goal of the study, spearheaded by Dr. Adam Anz and already eight years in the making, is to use stem cells to regrow cartilage.

If approved, it will be the first orthopedics study of its kind done in the United States and only the second in the entire world.

Stem cells are currently utilized most in cancer research and treatments, but Dr. Anz of the Andrews Institute wants to change that by putting regenerative medicine to the test, using stem cells to regrow knee cartilage.

The Andrews Institute already uses stem cells in certain therapies, but this new method could be a game changer.

"The bone marrow aspirate, which we're studying for knee arthritis and we can offer to patients, is the 1990's technology of stem cells," Dr. Anz said. "What we're studying is the modern way to harvest many more stem cells. That's the reason the FDA has said you need to bring this through our process before you just offer it to people."

Through a process called apheresis, stem cells are harvested from the patient with help from a synthetic hormone that promotes the body to generate more stem cells.

"Through this process we can collect millions of cells," Dr. Anz said. "Just 140 milliliters -- about a half of a coke can -- will have 140 million stem cells."

The stem cells will then be sorted, divided and injected into the patient's knee. Excess cells are stored in a nitrogen freezer at negative 181 degrees Celsius until the next round of injections, a process to be repeated over the next two years.

"If this study is successful, this will be the first approved in orthopedics in the United States," said Dr. Anz.

The study begins in May. Dr. Anz believes it will take about another five to seven years before the FDA can approve it for use in patients.
