The most common biologic interventional techniques involve platelet-rich plasma (PRP) and bone marrow aspirate concentrate (BMAC). Platelets injected into degenerated tissues are able to heal tears and initiate a regenerative response. Since 2013, the Bodor Clinic has had a 70% success rate for good to excellent results in the cervical, thoracic and lumbar spine. In 2020, Ryan Dregalla PhD, Yvette Uribe BS and Dr. Bodor published on how BMAC injected into disc material was capable of synthesizing hyaluronic acid, the gel in cartilage and discs. In 2021, they published on the safety and efficacy of combining PRP with local anesthetics to optimize patient comfort. Ongoing studies include using BMAC to heal the torn ACL, for which using a special ultrasound-guided technique the team is having a 90% success rate at restoring at least one bundle of the torn ACL and an 89-92% scores on the KOOS at 1 year. BMAC is most often used for osteoarthritis.
