Sparta is creating the first-of-its-kind chemically engineered cartilage platform, Hyalos.
The degeneration of cartilage between the joints can cause significant personal, economic, societal burden for individuals, families, and communities. In addition, acute injuries to joint cartilage can exacerbate and become debilitating over time.
We are developing cartilage-like implants for the all of the important joints in the body.
The first MTP hemiarthroplasty device combining Hyalos - a cartilage-mimicking hydrogel, with a proprietary titanium fixation technology for exceptional stability and bone integration.
Unlike traditional round implants, Carthyx replicates the unique biomechanics of the great toe, providing natural motion and long-lasting joint function.
With round-shaped implants, excessive cutting of the bone can lead to bad integration and loosening of the implant. With Carthix, only cartilage is removed and the cortical bone layer is smoothed.
Available in multiple sizes, the implant is designed to restore natural motion and long-lasting relief.










We are a team of operators, technologists, scientists, and engineers with long histories in the pharma, medtech, and nuclear arenas, and are driven by a common purpose; we seek to advance the standard of care for osteoarthritis and get people moving again without pain.
