1. A method, comprising:
incising an opening in a synovial capsule substantially surrounding a joint;
using a first tool to form an enlarged opening in the synovial capsule;
using a second tool to modify the joint if a bone structure is protruding into the joint, the bone structure if articulation of one or more bones forming the joint limits insertion of an implantable device, the joint being modified to receive the implantable device inserted into the joint using a third tool;
inserting using the third tool the implantable device having a saddle-shaped body and a plurality of protrusions, each of the plurality of protrusions being disposed at a corner of the saddle-shaped body and configured to prevent expulsion of the implantable device from the joint when the joint is articulated; and
positioning the implantable device using the third tool such that each of the plurality of protrusions is in intermittent contact with an adjacent surface of at least one of the one or more bones to prevent expulsion of the implantable device from the joint when the joint is articulated, the implantable device being uncoupled to any bone surface of the one or more bones of the joint.
