This breakthrough caught my eye. Could have big ramifications to orthopedics in the future.
In our industry, the landscape is dominated by mechanical innovations. Some of the biggest breakthroughs are not.
A Charité team in Berlin just published the world’s first dedicated clinical trial of CD19 CAR T-cell therapy in treatment-refractory rheumatoid arthritis in Nature Medicine.
Six patients.
One infusion of genetically reprogrammed immune cells.
Disease activity dropped in all six.
Three were in medication-free remission for up to a year.
That is not another TNF inhibitor with a prettier syringe. That is an attempt to erase the immune memory that keeps destroying joints.

Why This Matters in Orthopedics
RA starts when the immune system attacks the synovium: pain, stiffness, swelling. Then cartilage and bone get chewed up. The orthopedic consequence is familiar: destroyed joints, failed reconstructions,...
