Abstract
In one aspect, an implant for replacing subject tissue includes a nonbiologic portion and a biologic portion grown on the nonbiologic portion. The biologic portion may be grown on the nonbiologic portion before being implanted in the subject. The nonbiologic portion may comprise a porous metal substrate (e.g., scaffolding). The nonbiologic portion may be formed by 3D printing (i.e., additive manufacturing). The nonbiologic portion may be patient-specific. A robot may be used to shape the implant before implantation and/or to shape bone being replaced/resurfaced.

An implant for being implanted in a subject, the implant comprising:
- a non-biologic, three-dimensional (3D) printed shell configured to be implanted in a joint of the subject, the shell including a porous region having a porosity;
- bone tissue ingrown by incubation into pores of the porous region of the shell to form a bone part of the implant;
- and
- cartilage tissue grown by incubation on the bone part.
