Regenexx Procedures
The world's most published and precise interventional orthobiologic protocol — proprietary lab processing and micron-level image-guided delivery.
Regenexx procedures use proprietary laboratory processing that yields exponentially higher cell concentrations, delivered via extreme image-guided precision for superior clinical outcomes. As a certified Regenexx provider, our practice offers access to one of the most advanced interventional orthobiologic protocols available.
Pain Persists for a Reason.
Let's Find What's Driving Yours.
Not all biologic procedures are the same. The difference often lies in cell processing quality and placement precision. Regenexx is built on both — proprietary lab processing and image-guided delivery to the exact injury site.
Reveal → Repair → Restore → Renew
Regenexx Procedures is one tool within our four-stage pathway — selected based on your evaluation, not applied uniformly.
Reveal
We determine whether your condition is appropriate for a Regenexx-level biologic approach, using imaging and diagnostic reasoning to identify the precise tissue target.
Repair
Regenexx proprietary processing yields higher concentrations of therapeutic cells, delivered with micron-level image guidance to the exact injury site.
Restore
A structured rehabilitation plan supports the treated tissue as it responds to the biologic stimulus.
Renew
The goal is a durable return to activity — backed by the most published clinical outcomes registry in interventional orthobiologics.
What Makes Regenexx Different
Regenexx is not a single product — it is a comprehensive protocol with proprietary laboratory processing that yields significantly higher concentrations of therapeutic cells than standard bedside centrifugation used by most clinics.
Procedures are performed with advanced image guidance (fluoroscopy and ultrasound), allowing precise placement of the biologic into the exact injury site — at a micron level — rather than injecting blindly into the general area.
Regenexx maintains the world's largest tracked clinical outcomes database for interventional orthobiologics, meaning your procedure contributes to and benefits from published, peer-reviewed outcome data.
Diagnostic Evaluation
Imaging and clinical reasoning confirm the precise tissue target and procedure appropriateness.
Proprietary Processing
Regenexx lab processing yields higher cell concentrations than standard bedside systems.
Image-Guided Delivery
The biologic is placed at the exact injury site under real-time fluoroscopy or ultrasound.
Outcomes Tracking
Your progress is tracked and contributes to the Regenexx published outcomes registry.
