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.

PCL Injuries: Never simple, and not to be ignored

PCL Illustration
The PCL (posterior cruciate ligament) can be ruptured in car accidents when the knee hits the dashboard and in ski accidents when knees get impacted in wild falls. If left alone, the injured knee degrades over time. Understanding the injury and novel ways to treat it has changed its natural history.

Goodbye Stem Cells?

Stem Cell Under Microscope
The stem cell tsunami overwhelming all of medicine is evolving. Where once it was thought that these cells could morph into anything and cure everything, our new understanding of their behavior will change how they are used. Here is where we are on the learning curve:

Legal Olympic Blood Doping

Legal Olympic Doping
Classic blood doping—the injection of additional blood cells to increase oxygen in the muscle—is illegal in Olympic sports. Yet, legal blood doping is all the rage at the 2018 PyeongChang Olympics. Here is how it works.

The stem cell field as a whole has become crowded with companies proclaiming remarkable results. Unfortunately, many of the products offered lack stringent quality control.

The next generation of joint injections

relieve joint pain with injection of substance which stimulate the body's own healing.
The body heals best when it heals itself. To ease joint pain many physicians are now turning to injections, which work to stimulate and speed up the body’s natural healing process.
