Role of Collagen VI in Knee Function

Studies have revealed that the mutation or deletion of genes encoding for collagen VI can result in numerous musculoskeletal disorders, e.g. hip osteoarthritis, tissue fibrosis, tissue ossification, and muscular dystrophies. The deletion of the COL6A1 gene in mice was used to determine the function of collagen VI in the bone and cartilage of knee joints. The absence of collagen VI impacted the structure and shape of the knee joint, but did not critically affect physicality of the cartilage.
