Nanochon

Nanochon is a medical device company advancing orthopedic care with Chondrograft™, a 3D-printed, off-the-shelf implant designed to repair cartilage damage in the knee. Targeting 'pre-replacement' patients — those with focal cartilage defects who need more than temporary relief but aren't yet candidates for joint replacement — Chondrograft uses nanomaterial and 3D-printed collagen-mimicking structures to draw in blood and active cells from underlying bone, supporting the body's natural healing processes. The company completed a $4.1M oversubscribed Seed Prime II round in early 2026 to fund its first-in-human clinical trial.
