Abstract
Methods and systems for treating osteochondral defects (OCDs) are disclosed. The methods include collecting surface data of a joint using image-free methods, generating a three-dimensional (3D) healthy bone model based on the surface data and a database of healthy bone anatomies, defining a boundary of the OCD on the joint, and generating a 3D implant model based on the 3D healthy bone model and the boundary. The method may also include manufacturing an implant based on the 3D implant model, generating an implantation plan, resecting the joint according to the implantation plan, and placing the implant into the resected cavity. The 3D implant model may include a first and second porous layer separated by a nonporous layer. A polymer material is overmolded 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.
