Regenexx Patient Outcome Data

Regenexx maintains a unique active patient registry, where patients update their progress or side effects post-procedure. This registry includes tens of thousands of procedures performed by physicians in our network, making us the sole company tracking such a large orthopedic patient population treated with bone marrow concentrate. We provide transparent access to these outcomes on our website, empowering potential patients to make informed decisions about their treatment options.

Industry-Leading Musculoskeletal Specialists – Focused on Results

Regenexx patients benefit from the expertise of a board-certified physician who handles both their evaluation and their Regenexx procedure. Patients receive a treatment plan customized to their specific condition or injury needs. Regenexx non-surgical procedures are informed by research, utilize leading biotechnology, and are supported by over 19 years of patient results. These injection-based procedures require less downtime compared to surgery. Regenexx patients return to normal daily activities as tolerated. Most resume light activities and work after 5 to 7 days and return to sports at 6 to 8 weeks.
