1. An implant system configured for implantation in a joint, the implant system comprising:
a first part comprising an implant comprising:
a first portion comprising a hydrogel;a second portion comprising a porous material and the hydrogel in pores of the porous material; anda third portion comprising the porous material,the first portion being free of the porous material, andthe third portion being free of the hydrogel; and a second part comprising:
sidewalls;a bottom;a cavity at least partially defined by the sidewalls and the bottom, the cavity configured to at least partially receive the implant; andan anchoring element, one of the porous material and the sidewalls of the second part comprises a detent and the other of the porous material and the sidewalls of the second part comprises a groove configured to interact with the detent when the implant is at least partially in the cavity of the second part.
