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:

Hamstrings

Hamstring Tear
The dreaded “hammy” is the tearing of the muscle or tendon fibers of the powerful hamstring muscles at the back of the leg. It’s dreaded because the pain is sharp, and the recovery can be long. Here is what’s known and what’s new:

The Color of Life

Red The Color of Life
Red is the color. So much depends on red. Healthy red blood is the essence of all tissues and even the determinant of the health of bone. I look at life through this prism and notice the shades suggestive of this injury or that disease. I read those signals to predict outcomes.

What We Don’t Know

What We Don’t Know
What we think we know is probably not true. If we are practicing medicine the same way next year as we are practicing this year, we clearly haven’t learned anything.

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.

Why Joint Lubrication Works

Joint Lubrication
The natural lubricant of the human joint is called hyaluronic acid (HA). As part of a large, electrically-charged sugar molecule, HA permits water to be absorbed and released from the cartilage surface of the joints. This provides durability and compressibility. Without HA we would all grind to a halt.

Nano Communication

DNA-Language
What if we can learn to listen, understand, and respond to genetic communications? Could we have a genetic Fitbit and language translator? And, as gene editing techniques like CRISPR Cas-9 continue to become less expensive and more available, could we engage in a daily conversation with our personal genetic dictionary?

Amniotic Stem Cells: The Old New Solution

Amniotic Stem Cells: The Old New Solution
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.

Stem Cells vs. Growth Factors

Stem Cells vs. Growth Factors
Treatments for joint injuries have vastly improved during the past decade. Two of our best non-operative strategies are stem cell or growth factor injections. How do they differ—and which is best?

A Little Prick

A Little Prick
Short-term solutions for managing joint pain used to be limited to anti-inflammatory drugs and shots of cortisone. Today’s new injections can provide more than relief of symptoms.

Stem Cells Don’t Make Cartilage

Mesenchymal stem cells labeled with fluorescence molecules
Stem cell-based therapies, in which the body’s own cells are stimulated to contribute to the repair process, are enormously promising in all areas of medicine, including articular cartilage regeneration. Yet our understanding of stem cells continues to evolve.

Cortisone: The end of an era

A cortisone injection interferes with the body’s natural healing process
Cortisone is a therapeutic drug used to fight ailments ranging from asthma to arthritis. It was the athlete’s best friend throughout the 20th century. But in orthopedics, there is a significant downside.

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.

As we live longer, can our joints last longer, too?

New ways to heal joints can keep us fitter as we age
If we live longer, will our joints still work? While many diseases can kill you, arthritis has the potential to ruin your long life.

Avoid a chronically unstable ankle with a BioAnkle procedure

Avoid a chronically unstable ankle with a BioAnkle procedure
It’s possible to repair a chronically unstable ankle but it is best to help people avoid ever getting to that unstable stage by making sure that simple torn ligaments are stimulated to heal properly in the first place.
