What if the knee your doctor wants to replace could be repaired instead?
In a 15-year study, 82% of arthritic knees treated with the patient's own bone marrow never needed a knee replacement. Orthopedic surgeon Dr. Marc Pietropaoli stopped doing knee replacements in 2020, and he explains why most knee arthritis pain comes from the bone under the cartilage and what actually repairs it.
Meet our guestDr. Marc Pietropaoli is a sports medicine fellowship-trained orthopedic surgeon who trained under Dr. James Andrews and specializes in regenerative medicine. He founded Victory In Motion, home of Knee Repair, NOT Knee Replacement, and wrote the #1 Amazon best seller Repair NOT Replace. He was the first surgeon in the world to perform an FDA-approved BEAR ACL repair outside of clinical trials. Today his team combines bone marrow concentrate, properly dosed PRP, laser therapy, and whole-body rehab, with the goal of ending the need for knee replacements by 2043.
