Articular cartilage repair
First Claim
1. A cartilage repair implant for repair and regeneration of a cartilage lesion, the implant comprising:
- a three-dimensional scaffold comprising at least three layers of woven fibers; and
a three-dimensional porous substrate fixedly coupled to the scaffold and configured to press fit and integrate into bone, wherein,the three-dimensional porous substrate comprises a first three-dimensionally printed layer and a second three-dimensionally printed layer arranged on top of the first three-dimensionally printed layer,the first three-dimensionally printed layer includes a first plurality of extruded struts oriented in a first strut direction,the second three-dimensionally printed layer includes a second plurality of extruded struts oriented in a second strut direction, andthe second strut direction is angled approximately 30 degrees to approximately 120 degrees relative to the first strut direction.

Abstract
An implant is configured for repair and regeneration of cartilage lesions. The implant includes a three-dimensional woven textile scaffold and a three-dimensional rigid, porous substrate. The scaffold is bonded to the substrate such that the substrate supports the scaffold. The substrate is configured to be inserted into bone tissue including cartilage lesions such that the substrate and the scaffold replace the bone tissue including the cartilage lesions. The substrate and scaffold are further configured such that after the substrate and the scaffold have replaced the bone tissue including the cartilage lesions, the substrate and scaffold promote growth and integration of new bone tissue into the implant.
