The role of collagen in ligaments
Ligaments are short strands of fibrous connective tissue rich in collagen (almost 80%), representing an extremely solid structure with multiple functions.Among other functions, ligaments connect bones across joints, but they do not attach bones to muscles, as tendons carry out this function. Certain ligaments are responsible for joint stability, avoiding false movements. This protects the integrity of joints when there is a sprain, and prevents dislocations when there is a forced movement (hyperflexion or hyperextension). Notably, there is a complex system of eight ligaments that reinforces the knee bones to form a very resistant joint capsule.
