1. A method for securing tissue to an implant comprising:
preparing a target site of a subject;
inserting an implant into the target site, the implant comprising:
a docking recess defining a perimeter of about 5 to 10 millimeters, and configured to receive one or more tissue structures and defining at least one opening extending from the docking recess through an outer surface of the implant, wherein the at least one opening is configured to receive a suture and the implant comprises a transition area between the outer surface and the docking recess;
the outer surface comprising:
a porous osteointegration region; and
at least one smooth region, the at least one smooth region comprising a lower coefficient of friction than the porous osteointegration region;
stitching the suture to the one or more tissue structures, wherein the one or more tissue structures comprise a portion of bone attached to a ligament of the subject; and
securing the one or more tissue structures to the implant by:
threading the suture through the implant via the at least one opening;
inserting the one or more tissue structures into the docking recess; and
securing the suture over the at least one smooth region.
