What’s Hot & What’s Not in Knee Surgery: A Few of the Highlights

What’s Hot & What’s Not in Knee Surgery:
Stem cells are both in and out. It was once thought that if these cells were injected into joints, they would turn into cartilage. Two problems arose. First, patients (unless they are infants) have very few stem cells left. Second, the injected cells died after releasing their instructional growth factors, never turning into cartilage. But what we have learned is that an increasing number of concentrated growth factors, immune stimulants, and even some drugs can induce the migration of the body’s own progenitor cells—some of them stem cells—cells that direct healing—to the injured area. These cells then optimize the environment around the injury to effect healing.

Chicken Soup: What’s New in the Field of Cartilage Repair?

Primordial Soup
The science of cartilage repair for joints is in full swing. There is a frenzy of activity around stem cells, growth factors, exosomes (small packets of growth factors), and all forms of stimulation therapies. And the matrices or patches that those factors are placed on vary widely. The bottom line is that no one factor does it all. Here is the latest update on what needs to go into the chicken soup of tissue repair to make you well.
