Ligaments are classified as dense connective tissue, and they consist of a protein substance called collagen. The organisation of collagen fibres gives the ligament its tensile strength.
Another function of ligaments is to provide input to the brain that allows a person to know what position the joints are in, without having to look. This helps to perform the complex coordinated activities needed for sport.
A normal ligament consists of:
• 9% Type 3 collagen
After being laid down by fibroblast cells it takes approximately three months for Type 3 collagen to mature into Type 1 collagen. As with other cells in the body, this process of renewal occurs continually.
