New Arthritis Research Shows the Body Knows How to Heal

Exciting new research is shedding light on something we have long believed at Greenberg Regenerative Medicine: the body has an incredible ability to heal itself when given the right signals
According to Dr. Scott Greenberg, a physician on the medical staff at Bryn Mawr Hospital, emerging arthritis research is shifting the conversation away from simple degeneration and toward regeneration.
A recent Stanford University study titled “Inhibition of 15-hydroxy prostaglandin dehydrogenase promotes cartilage regeneration” demonstrated that blocking a protein called 15-PGDH led to cartilage regeneration in mice with osteoarthritis. Rather than slowing damage alone, researchers observed measurable cartilage repair and pain reduction.
What the Study Found
Researchers identified several important findings:
• 15-PGDH increases in joints with age and injury
• Blocking this protein led to cartilage regeneration in a mouse model
• Regeneration occurred by reactivating existing cartilage cells
• Pain associated with osteoarthritis was reduced
This is significant because it suggests that osteoarthritis may be biochemically modifiable. Instead of viewing arthritis as an irreversible wearing down of cartilage, the study supports the possibility that joint tissue can shift back toward repair under the right conditions.
While animal studies do not automatically translate to humans, they provide an important proof of concept.
How This Connects to Our Approach in Bryn Mawr
From our Bryn Mawr office serving patients across Philadelphia and the Main Line, we focus on stimulating the body’s natural repair systems rather than bypassing them.
According to Dr. Greenberg, arthritis treatment should not be limited to suppressing inflammation or replacing joints. It should address biology and mechanics together.
At Greenberg Regenerative Medicine, we utilize autologous regenerative therapies including VSELs, adipose-derived cells, PRP, and prolotherapy. These treatments aim to:
• Modulate inflammation
• Stimulate cartilage-supporting pathways
• Promote tissue repair using the patient’s own cells
Because these therapies use the patient’s own biologic material, they are designed to work with the body’s signaling systems rather than override them.
Why Mechanics Matter in Arthritis
Biochemistry alone is not enough.
Even if cartilage regeneration occurs, abnormal joint mechanics can continue to create destructive forces. According to Dr. Greenberg, correcting instability and gait abnormalities is foundational to long-term improvement.
Through the Greenberg Method, we analyze full-body mechanics to identify underlying drivers of joint stress. This may include correcting pelvic tilt, improving muscular stabilization, and addressing spinal alignment patterns.
For patients traveling from Philadelphia and surrounding communities, this comprehensive approach is often what differentiates regenerative care from symptom management alone.
Healing Instead of Replacing
Joint replacement has an important role in orthopedic medicine. However, not every patient requires surgery as a first step.
This research reinforces a larger shift in arthritis care: under certain biological conditions, joints may be capable of repair.
While outcomes vary depending on severity, imaging findings, and overall health, growing evidence supports a more regenerative model of care.
Our goal is not simply to manage symptoms. It is to restore function whenever possible.
Frequently Asked Questions
Can cartilage regrow once it’s damaged?
According to Dr. Scott Greenberg, cartilage regeneration is possible in certain cases.
Advanced imaging studies have shown measurable cartilage changes following regenerative procedures. In one documented case study, arthroscopy performed before and after treatment confirmed healing of a torn meniscus using autologous stem cell derivatives obtained from adipose tissue.
Adipose tissue is known to be one of the richest sources of regenerative cells in the body.
Is arthritis reversible?
According to Dr. Greenberg, arthritis should be understood as both a biological and mechanical condition.
In some patients, inflammation and degeneration can be reduced, and function significantly restored. However, reversibility depends on stage and structural damage.
The Greenberg Method emphasizes joint stabilization and biomechanical correction in addition to biologic therapies.
How do stem cells help with arthritis?
Stem cells and related regenerative cells may help by modulating inflammatory pathways and supporting cartilage matrix production.
According to Dr. Greenberg, combinations of VSELs and adipose-derived cells are used selectively based on patient presentation. These cells may promote proteoglycan production, similar to what gel injections aim to supplement, but through endogenous signaling.
Mechanical stabilization remains a critical component of care.
What are VSEL stem cells?
Very Small Embryonic-Like Stem Cells, or VSELs, are small, dormant regenerative cells found in adult tissues.
According to Dr. Greenberg, their small size may allow broader distribution within the body compared to larger cell types. They are being studied for potential roles in tissue repair.
Are regenerative arthritis treatments natural?
At Greenberg Regenerative Medicine in Bryn Mawr, regenerative treatments utilize the patient’s own tissue.
This autologous approach differs from some international clinics that use donor cells.
How long can regenerative treatments delay joint replacement?
According to Dr. Greenberg, outcomes vary widely.
Some patients experience prolonged functional improvement for many years, while others may eventually require surgical intervention.
Severity on imaging, biomechanics, and overall health all influence duration.
Is regenerative arthritis treatment safe?
Regenerative treatments using autologous tissue are generally well tolerated when performed appropriately.
As with any procedure, risks exist and are discussed during consultation.
Compared to joint replacement surgery, complication rates are typically lower, but individual risk profiles vary.
What results can patients realistically expect?
The goal of regenerative care is meaningful pain reduction and functional improvement.
Some patients experience dramatic improvement. Others experience partial but significant relief.
According to Dr. Greenberg, results depend on accurate diagnosis, mechanical correction, biologic responsiveness, and patient adherence to rehabilitation.
