A commercial product that is formed from collagen material pre-shaped into a knee meniscus.
By soaking the scaffold in the patient's blood or specially-prepared cells, the cells regenerate using the collagen scaffold as a template.
Collagen implants are relevant where there is a defect in the meniscus that could be filled by the implant, but the anterior and posterior horns of the meniscus and the outer rim are intact.
