Ulnar-Sided Wrist Pain After Overuse: Is It the TFCC, Arthritis, or a Triquetral Cyst?
By Marc Darrow, MD, JD A physical therapist describes a frustrating problem: persistent pain on the little-finger side of the left wrist after overuse. MRI shows degenerative changes in the triangular fibrocartilage complex, arthritis in the pisotriquetral joint, and a cyst in the triquetrum. The hand surgeon thinks the TFCC looks relatively good and suspects […]

PRP, Stem Cells, or Exosomes? Choosing an Injection for Joint and Tendon Pain
By Marc Darrow, MD, JD A caller to my August 29, 2026, Living Pain-Free radio show asked a question I hear often: If you have a torn shoulder tendon and want to avoid surgery, should you choose platelet-rich plasma (PRP), a treatment using cells from your own bone marrow, or exosomes? Another caller wanted to […]

Stem cell therapy for ACL tear | Non-surgical options
Can Stem Cell Therapy Help ACL Tears Heal Without Surgery? For many years, patients with a torn anterior cruciate ligament, or ACL, were told that the ligament could not heal on its own and that reconstruction surgery was the only path back to sports, exercise, or an active lifestyle. Today, that conversation is changing. Emerging […]
Exosomes and osteoarthritis
Osteoarthritis is often described as simple “wear and tear,” but the condition is more complex than cartilage gradually thinning over time. It involves a combination of inflammation, cartilage breakdown, changes in the joint lining, stress on cartilage-producing cells, and remodeling of the bone beneath the joint surface. Together, these processes can contribute to pain, stiffness, […]
Stem cell therapy for Triangular fibrocartilage complex tear
The TFCC is a structure on the ulnar (pinky) side of the wrist that helps keep the wrist bones stable and absorb shock when the wrist moves or bears weight, Injuries to the TFCC will generally cause loss of range of motion and grip strength. There is limited research specifically on stem cell therapy for […]
Stem cell therapy for carpal tunnel syndrome
Marc Darrow, MD, JD. In our clinic, common diagnoses treated with regenerative medicine include nerve entrapments like carpal tunnel syndrome. Research into the use of stem cells for carpal tunnel syndrome is in its early years. Stem cells, taken from a patient’s bone marrow, are reinjected into the carpal tunnel region to promote healing and […]
Stem cell therapy for adhesive capsulitis
Frozen shoulder (adhesive capsulitis) happens when the lining of the shoulder joint becomes inflamed, then develops scar tissue. The capsule around the joint thickens, stiffens, and tightens, which limits how far the shoulder can move and causes pain. It usually gets better on its own over 12–24 months, but recovery is not always complete. Stem […]

Stem cell therapy for tendon overuse injury
Overuse Injury and Inflammation Overuse injuries, such as tendonitis, occur when repetitive stress is placed on a tendon, leading to inflammation. The “-itis” in tendonitis indicates this inflammatory response. Sometimes, this natural response enables the injured area to recover on its own. The Timeline and Phases of Healing Healing from tendon injuries follows a specific […]
