Pro-Stride APS

Autologous Protein Solution Device

Pro-Stride APS is a proprietary dual-device system whose output produces a concentrated solution of cells, platelets, growth factors, and anti-inflammatory proteins (including IL-1ra and other anabolic proteins).


  • All-Natural (from patient's own blood)

  • Clinically demonstrated effectiveness*

  • Convenient (no incubation, <20-minute processing, ambulatory)

Interleukin-1, also known as IL-1, and tumor necrosis factor alpha, also known as TNF-alpha, are the key pro-inflammatory proteins called cytokines which need to be blocked from damaging the tissue.  These inflammatory cytokines bind to the cell surface receptors on the cartilage and start the process of cartilage breakdown which ultimately leads to joint pain and damage.  


There are several naturally occurring inhibitors (anti-inflammatory proteins) of the pro-inflammatory cytokines IL-1 and TNF-alpha.  These include the interleukin-1 receptor antagonist protein (IRAP), also known as IL-1ra, SIL-1r, also known as Soluble interleukin-1 receptor and STNF-rs, known as Soluble tumor necrosis factor receptors. All of these are highly concentrated within Pro-Stride APS. 

  • Pro-Stride does not require an incubation period

  • Pro-Stride's output is not an autologous conditioned serum (ACS)

  • Pro-Stride's output is never frozen
