Abstract
The invention relates to a joint implant for new tissue formation at a joint, the joint implant (1) comprising a pinlike body having a bottom region (11), a top region (12) and a shell region (13), wherein at least the top region (12), of the joint implant (1) has a hydrophobic surface for promoting chondroblastic differentiation of mesenchymal stem cells.
Claims17
Joint implant that forms new tissue at a joint, the joint implant (1) comprising a pinlike body comprising an elongated solid that is impervious to liquid, wherein the elongated solid has a non-porous interior, a bottom region (11), a top region (12) and a shell region (13), characterized in that:
- at least the top region (12) and the shell region (13) of the elongated solid comprise a hydrophobic surface that promotes chondroblastic differentiation of mesenchymal stem cells, wherein an artificial trabecular structure (14) extends radially outward from the side of the pinlike body;
- and the bottom region (11) includes a hydrophilic surface that promotes bone growth.
