Abstract
Methods, systems, and devices for treating osteochondral defects (OCDs) are disclosed. The disclosed methods and systems include collecting joint surface data using image-free methods, generating a three-dimensional (3D) healthy bone model based on the joint surface data and a database of healthy bone anatomies, defining the OCD boundary on the joint, generating a 3D implant model based on the 3D healthy bone model and the OCD boundary, manufacturing an implant based on the 3D implant model, generating an implantation plan, the resected cavity on the joint. The implant includes a 3D-printed titanium alloy substrate having a first and second porous layer separated by a nonporous layer. A polymer material is over-molded onto the second porous layer and treated to exhibit properties that mimic cartilage, while the first porous layer allows the implant to fuse to patient bone.
