SUPERIOR SOLUTION

Experience PhaseOne Antimicrobial Solution as part of an overall infection control strategy against Periprosthetic Joint Infections.

(Intended for use by or on the order of a licensed healthcare practitioner.)

  • No-Rinse Formula

    Our no-rinse formula is efficient and easy to use.

  • Non-Cytotoxic

    Hypochlorous acid (HOCl) is naturally produced as part of our immune system during phagocytosis so it’s non-cytotoxic and kind to tissue.

  • The Miracle Molecule

    HOCl is 100x more effective than Dakin’s (bleach) while safe on living tissue and healing cells.

  • Medical Device

    Considered a medical device by regulatory standards.

PERIPROSTHETIC JOINT INFECTION (PJI)

THE CRITICAL PROBLEM

PJIs are a cancer-like killer in joint replacement surgeries. They are considered serious complications of joint replacement surgeries where bacteria or fungi infect the area around the artificial joint. This condition significantly increases a patient's risk of death compared to patients who undergo non-infected (aseptic) revision surgeries. 

  • Studies report that the associated 5-year mortality rate of PJIs are up to 26%. The 5-year mortality rate for breast cancer is often cited at 11%. 

    PJI outcomes can be worse than those for some types of breast cancer, which has led medical professionals to emphasize the seriousness and "malignant nature" of PJIs.

  • Projections for the year 2030 estimate that the annual number could be around 40,000 PJI cases for total knee arthroplasties (TKA) and 26,000 for total hip arthroplasties (THA), totaling 66,000 cases for those specific joints.

  • The combined annual hospital costs related to hip and knee PJIs alone were projected to be approximately $1.8 billion by 2030.

    Cost Per Patient: The cost of treating a single PJI case is much higher than an uncomplicated primary joint replacement, often five times as much. Individual case management can average around $90,000 to over $100,000. Some estimates of the lifetime economic cost of treatment for a single 65-year-old patient with an infected hip PJI can be as high as approximately $390,806.

  • There is a clear trend of increasing antibiotic-resistant pathogens in PJIs, which often necessitate revision surgeries.

  • Chemicals such as CHG and PVP-I have demonstrated detrimental effects to both articular cartilage viability and human osteoblasts.⁴ ⁵ ⁶

“Most studies show the contemporary prevalence (of PJI) is somewhere around 2% to 2.2%. It’s quite a bit. It hasn’t moved over the last 40 to 50 years.”

PHASEONE

A POWERFUL SOLUTION

PhaseOne delivers the power of pure, stable HOCl as a preservative in the bottled solution, allowing effective rinsing of dirt, debris, and microorganisms from surgical wounds.

PhaseOne optimally supports infection control strategies - offering a solution that mechanically cleanses and removes wound debris without compromising tissue safety.

  • Hypochlorous acid (HOCl) is naturally produced as part of our immune system during phagocytosis so HOCl is non-cytotoxic and kind to tissue. When neutrophils encounter bacteria or other pathogens, the neutrophils engulf it, generate HOCl and destroy the microorganism.⁷

  • HOCl is 100x more effective than Dakin’s (bleach) and safe on living tissue and healing cells.⁷

  • PhaseOne is manufactured in an ISO-certified facility and has passed USP sterility <71> and endotoxin <85> testing, and is backed by extensive in vivo and in vitro clinical data that demonstrate the product's efficacy as part of an overall infection control strategy.
