35. A method of forming fibrous tissue at a site of damaged cartilaginous tissue of a bone joint, the method comprising the steps of:
-
(i) violating the subchondral bone plate at said site using a technique selected from the group comprising drilling, abrasion, or microfracture;
said technique leading to local bleeding and transport of bone marrow cells into the bone and to subsequent formation of fibrous scar tissue; and
(ii) positioning a biocompatible mesh scaffold at said site;
wherein said scaffold raises the level of the resultant fibrous tissue to level or substantially level with the surrounding cartilage. - View Dependent Claims (36, 37)
