  • Publication number: 20230055112
    Abstract: There is disclosed a collagen construct comprising a plurality of elongate strips, wherein each strip contains a plurality of collagen fibres that are substantially aligned along the length of the respective strips, and the strips are braided or woven together to produce a collagen construct in the form of a rope that can be used for replacing tendons or ligaments, such as cruciate ligaments. Also disclosed is a method for making or producing the collagen construct from a collagen membrane having a plurality of collagen fibres being substantially aligned parallel to each other in a common direction. The membrane is cut along cut lines that are orientated substantially parallel to that common direction, thereby to separate elongate strips from the membrane. The strips are then braided or woven together to form the collagen construct.
