Globally, 595 million people live with osteoarthritis (OA). This number is projected to reach 1.04 billion by 2050.*

Our mission is to treat osteoarthritis and get people moving without pain.

About

Sparta Biomedical is creating the first-of-its-kind chemically engineered cartilage platform, Hyalos.

The degeneration of cartilage between joints can cause significant personal, economic, and 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.

Hyalos Spotlight

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, Karthyx 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 Karthyx, 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.
