It is an established fact that the correct knee joint function depends on excellent lubrication and uniform distribution of loads in different compartments. Chondral and Osteochondral lesions of the knee cause therefore and important derangement of the function. Despite the various treatment options available, symptomatic articular cartilage defects continue to represent a therapeutic challenge for knee surgeons.
Cartiva® Synthetic Cartilage Implant (SCI) is intended to treat focal chondral or osteochondral defects of the articular cartilage surface associated with joint pain or decreased range of motion. The implant, a cylindrical device made from an elastic biomaterial, may be used as a replacement for damaged cartilage and bone without requiring the destruction or removal of a patient's healthy tissue. It is intended for use during a single surgical procedure. The procedure is similar to that used for osteochondral autograft or allograft transplantation; a part is placed into a pre-drilled hole to resurface the damaged area of cartilage/bone.
Cartiva® SCI is made from a proprietary biomaterial. The device, which is classified as a hydrated polymer, consists of water in similar proportion to human tissue. The organic polymer-based biomaterial is capable of withstanding repetitive loading typical of normal walking conditions, and its mechanical properties are similar to articular cartilage. Cartiva® SCI provides an alternative to tissue-based treatments, without exposing the patient to the risk of viral transmission or an inflammatory response because it does not contain substances derived from animal or human tissue.
Cartiva® SCI is supplied in a range of sizes for selection by the physician. The device is supplied sterile and is packaged as a single unit.
Our unique cartilage replacement technology can revolutionize the way you treat chondral and osteochondral defects in the knee by offering patients an alternative that:
