OSSTEC is a London-based Imperial College London spinout developing 3D-printed joint replacement implants. Its first product is a cementless, less invasive partial knee implant that mimics the structure of cartilage and bone-fixing elements to stimulate bone growth. The design aims to overcome common challenges of traditional knee replacements and reduce the risk of implant failure. By leveraging 3D printing, OSSTEC says it simplifies the supply chain, improves manufacturing efficiency and could reduce costs for healthcare systems. The company plans to use newly raised funds to accelerate the launch of its technology, scale operations and engage strategic partners in the medical field. Leadership highlights clinical and workflow advantages of cementless partial knee replacement and the potential for improved fixation, survival and outcomes for patients and surgeons. OSSTEC builds porous, 3D‑printed titanium implant structures designed to emulate natural bone behaviour and stimulate bone in‑growth rather than relying on cement fixation. The technology originates from research in Imperial College London’s Department of Mechanical Engineering and includes a software platform to drive 3D printing of the structures. Animal data reportedly show improved healing and bone in‑growth versus conventional implants, and the company has human cadaveric data supporting translation to people. OSSTEC is preparing prototypes for regulatory testing and the first clinical studies, working to ensure implants can withstand expected loads and stresses. Management emphasizes engagement with surgeons to validate clinical needs and drive adoption. The company has received prior support including an Innovate UK grant in 2022 and contributions from Imperial College’s enterprise funders.
