GelrinC is an investigational device being evaluated as a treatment to help the body regrow cartilage in the knee.

Articular cartilage is the smooth, white tissue covering the ends of bones where they come together to form joints. Damage to the cartilage layer can be extremely painful for patients and is generally associated with sudden trauma. Surgical intervention is often required because of the limited capacity for cartilage to repair itself.

The current standard of care is called microfracture, which involves drilling small holes in the underlying bone to allow a blood clot to form within the defect. However, microfracture often provides only short-term relief and may require repeat surgeries.

Regentis Biomaterials president and CEO Alastair Clemow said: “Cartilage repair is the largest unmet need in orthopedic sports medicine today. GelrinC enables patients to harness the benefits of their own stem cells to promote cartilage regeneration in a single, minimally invasive procedure.”

People with knee pain caused by damaged articular cartilage who would like to be considered for the study can inquire by visiting or by calling (833) 430-8686.

The following orthopedic centers are currently or will soon be recruiting patients, with additional sites to be added soon in Denver, Colorado; San Francisco, California; Orlando, Florida; and Portland, Oregon.
