Biocartilage allograft contains living _____.

The correct choice is that biocartilage allograft contains living chondrocytes. Chondrocytes are the specialized cells found in cartilage that play a crucial role in maintaining the cartilage matrix and its overall health. Their presence in an allograft is vital because they are responsible for producing the extracellular matrix components, such as collagen and proteoglycans, which provide structural support and resilience to the cartilage.

The presence of living chondrocytes in biocartilage allografts enhances the graft's ability to integrate with the host tissue and supports healing and regeneration. This is particularly important in joint repair and cartilage restoration procedures, where the goal is to restore the functionality of the damaged area.

Understanding the role of chondrocytes in biocartilage allografts is essential for anyone involved in musculoskeletal medicine and sports rehabilitation, as it directly relates to the effectiveness of treatments for cartilage-related injuries.
