Product catalog summary
Overview: The Zimmer DeNovo NT Natural Tissue Graft is a biologic treatment designed for early intervention and repair of articular cartilage. It is a juvenile cartilaginous allograft tissue that provides a single-stage procedure with fibrin fixation, eliminating the need for harvesting a periosteal flap.
Juvenile Cartilage Tissue: The graft consists of scaffold-free living articular cartilage with biochemical properties similar to those found in young, healthy joints. Juvenile cartilage has a higher cell density and proliferation rate compared to adult cartilage, and it synthesizes more glycosaminoglycan (GAG), which decreases inflammation and aids in cartilage repair.
Cartilage Injury and Treatment: Adult articular cartilage has limited self-repair capacity. Untreated focal defects can lead to cartilage breakdown and arthritic degeneration, eventually necessitating joint replacement. DeNovo NT Graft offers a simple alternative for treating focal cartilage defects.
Clinical Experience: With over 7,000 grafts used in various anatomical applications, including the knee, foot, ankle, elbow, shoulder, and hip, the DeNovo NT Graft has shown significant improvements in pain, function, and activity scores in clinical trials.
Comparative Analysis: The document compares DeNovo NT Graft with other cartilage repair treatments such as Autologous Chondrocyte Implantation (ACI), Bone Marrow Stimulation, Osteochondral Autograft, Osteochondral Allograft, and Micronized Cartilage Matrix. DeNovo NT Graft is noted for its single-stage surgery and applicability to multiple joints.
Key Data: Pre-clinical studies indicate that juvenile bovine cartilage has significantly higher cell density and proliferation rates than adult cartilage. Clinical outcomes show significant improvement in pain and function over baseline in knee patients 24 months post-implant.
