A D1 athlete from the Northeast came to us with chest pain imitating costochondritis (and many other orthopedic injuries), but after detailed exam and imaging, the chest pain was found to be rare erosive arthritis of the cartilaginous manubriosternal joint causing severe chest pain to any pressure (normal ECG & ECHO). Also note the severe loss of bone density in the manubrium. This type of arthritis is frequently associated with autoimmune conditions, spondyloarthropathies, and inflammatory diseases, so an extensive set of labs was ordered, and even though she was seronegative for the classic RF, she had extremely high 14-3-3η positivity (rheumatoid arthritis marker) and extremely high Bartonella antibodies (lyme disease). The cartilaginous manubriosternal joint was patched with autologous bone marrow stem cell grafting with PRF scaffolding matrix, and she is now considering further disease-modifying peptides, proteins, and biologic agents (DMARDs), as well as basic high-dose Vitamin D3+K2 strategies. Careful diagnosis and attention to detail is essential as many rheumatic diseases also imitate, overlap, and involve orthopedic injuries.
We use 3D image-guidance to perfectly patch critical targets with a sticky protein scaffolding matrix to adhere the stem cells onto the cartilage (like re-paving a pothole in the road with asphalt) and place stem cell grafts into avascular necrosis, stress fractures, and subchondral intraosseous cysts (like patching a foundation with mortar). The high-resolution intra-operative 3D imaging enables perfect filling of the defects with the stem cell matrix graft, which adheres the stem cells directly to the injuries and enables them to integrate and thrive while rebuilding these structures. We can also place a variety of optional peptide signaling molecules to further promote repair processes and regulate autoimmunity. No other place on the planet is using such cutting-edge technologies of tissue-engineered stem cell patches with 3D image-guidance.
