Millions of Americans are in pain. Arthritic joints make exercise difficult, even though moving is one of the best things we can do for joint pain. Pinched nerves can cause excruciating, long-lasting pain. The usual treatments, such as NSAIDs, may help ease the pain momentarily, but do nothing to help heal the underlying condition. What do you know about the new science of regenerative therapies?

The New Science of Regenerative Therapies
What is the price of pain relief for aching, arthritic joints? We’re not talking about the drugstore sticker on a bottle of ibuprofen. Instead, we are referring to the potential negative consequences of utilizing such medicines for temporary symptomatic relief when the joint continues to hurt for weeks, months or years. Even more powerful treatments, such as corticosteroid injections into the sore joint, don’t heal the cartilage. In fact, they may contribute to further deterioration as they suppress the immune system. Our guest offers other ways to treat joint pain with regenerative therapies.
Immune Mechanisms That Resolve Inflammation
Dr. Tom Buchheit is a pain management specialist who has worked with elite athletes as well as seniors to get them moving well again after an injury. One of the reasons exercise can be so helpful is that the right kind and amount of movement creates good inflammation. Unlike chronic inflammation that causes further harm, good inflammation helps the immune system switch to a different phase, one in which destructive pathways are resolved. The three pillars of exercise are aerobic exercise, muscle building exercise and exercise to improve balance. Together, these types of exercise help recovery and healing and can even help heal damaged nerves. NSAIDs like naproxen, celecoxib or ibuprofen can interfere with the good inflammation exercise creates. Rather than taking such a pill before a game or workout, it makes sense to wait and take it afterwards if you need it.
Will Exercise Wear Out Your Joints?
Injury can damage the joints, but the idea of osteoarthritis as a consequence of wear and tear seems to be a medical myth. Instead, we might think of osteoarthritis as a chronic wound that may need regenerative therapies to heal properly. Immune system building blocks like omega-3 fats in the diet and a wide palette of colorful produce can help with the healing. Movement itself is part of the healing process.
What Are the Regenerative Therapies?
PRP
Some of the therapies we think of as “new” have actually been in use for several decades. One of these is platelet-rich plasma, which was initially developed to help wounds heal. In this treatment, the doctor uses the patient’s own blood. The plasma with as many platelets as possible concentrated in it is then carefully injected into the painful joint. The idea, again, is to cause “good inflammation,” alerting the immune system that healing is needed here and encouraging it to flip into inflammation resolution mode. Not all studies of platelet-rich plasma (PRP) have shown benefit, but some of that may be due to using plasma that is not truly rich in platelets. Properly prepared PRP works especially well for ligaments and tendons, according to Dr. Buchheit.
MSC
If you hear someone talk of getting a “stem cell” injection, they are talking about MSC. They were originally misnamed mesenchymal stem cells, but would be better termed medicinal signaling cells. They too are derived from the patient’s own body. Rather than rebuilding cartilage, they also signal the immune system to switch from long-term damaging inflammation to short-term healing inflammation. This is also the idea behind prolotherapy, in which the therapist injects sugar water into the joint. That may sound like a placebo, but it can be effective at easing pain and helping healing.
Autologous Conditioned Serum
Dr. Buchheit describes another of the regenerative therapies, autologous conditioned serum. Blood is drawn and encouraged to clot; then the serum is injected into the troublesome joint. Clotting helps create powerful signals that healing is needed. This therapy is not widely available, as only about ten places in the US have the dedicated laboratories required to prepare ACS properly.
Hydrodissection
Dr. Buchheit also describes how to use injections to free up trapped nerves in a process called “hydrodissection.” This is often very helpful in alleviating chronic neuropathy. We conclude the episode with a brief reminder of how to stay healthy once you get nerves and joints feeling good again.
This Week’s Guest
Thomas Buchheit, MD, served as Chief of Pain Medicine at Duke from 2013-2019 and led several NIH- and DoD-funded research studies. His focus is on immune mechanisms that resolve inflammation and pain.
In 2025, Dr. Buchheit completed his book, Healing Joints and Nerves: Immune Stimulation and the New Science of Regenerative Therapies, and founded Triangle Regen Medicine and Biologics Center. His overarching goal is to help patients understand and use regenerative therapies to activate their own healing and repair mechanisms. He continues to serve as adjunct associate professor at Duke and collaborates with colleagues at the Center for Translational Pain Medicine.
