As used herein, "implant" refers to a medical device manufactured to replace a missing biological structure, support a damaged biological structure, or enhance an existing biological structure. Often medical implants are man-made devices, but implants can also be natural occurring structures. The surface of implants that contact the body may be made of, or include a biomedical material such as titanium, cobalt chrome, stainless steel, carbon fiber, another metallic alloy, silicone, polymer, Synthetic polyvinyl alcohol (PVA) hydrogels, biomaterials, biocompatible polymers such as PolyEther Ether Ketone (PEEK) or a polylactide polymer (e.g. PLLA) and/or others, or apatite, or any combination of these depending on what is functional and/or economical. Implants can have a variety of configurations and can be wholly, partially, and/or include a number of components that are flexible, semiflexible, pliable, elastic, supple, semi-rigid, or rigid. In some cases implants contain electronics, e.g. artificial pacemaker and cochlear implants. Some implants are bioactive, such as subcutaneous drug delivery devices in the form of implantable pills or drug-eluting stents. Orthopedic implants may be used to alleviate issues with bones and/or joints of a patient's body. Orthopedic implants can be used to treat bone fractures, osteoarthritis, scoliosis, spinal stenosis, discomfort, and pain. Examples of orthopedic implants include, but are not limited to, a wide variety of pins, rods, screws, anchors, spacers, sutures, all-suture implants, ball all-suture implants, self-locking suture implants, cross-threaded suture implants, plates used to anchor fractured bones while the bones heal or fuse together, and the like.

As used herein, a "body" refers to a main or central part of a structure. The body may serve as a structural component to connect, interconnect, surround, enclose, and/or protect one or more other structural components. A body may be made from a variety of materials including, but not limited to, metal, plastic, ceramic, wood, fiberglass, acrylic, carbon, biocompatible materials, biodegradable materials or the like. A body may be formed of any biocompatible materials, including but not limited to biocompatible metals such as Titanium, Titanium alloys, stainless steel alloys, cobalt-chromium steel alloys, nickel-titanium alloys, shape memory alloys such as Nitinol, biocompatible ceramics, and biocompatible polymers such as Polyether ether ketone (PEEK) or a polylactide polymer (e.g. PLLA) and/or others. In one embodiment, a body may include a housing or frame or framework for a larger system, component, structure, or device. A body may include a modifier that identifies a particular function, location, orientation, operation, and/or a particular structure relating to the body. Examples of such modifiers applied to a body, include, but are not limited to, "inferior body," "superior body," "lateral body," "medial body," and the like. |

As used herein, "bone engagement surface" refers to a surface of an object, instrument, or apparatus, such as an implant that is oriented toward or faces one or more bones of a patient. In one aspect, the bone engagement surface may abut, touch, or contact a surface of a bone. In another aspect, the bone engagement surface or parts of the bone engagement surface may be close to, but not abut, touch, or contact a surface of the bone. In certain aspects, the bone engagement surface can be configured to engage with a surface of one or more bones. Such a bone engagement surface may include projections and recesses that correspond to and match projections and recesses of the one or more bone surfaces. |

As used herein, “side” refers to a structure or part of a structure including, but not limited to: one of a longer bounding surfaces or lines of an object especially contrasted with the ends, a line or surface forming a border or face of an object, either surface of a thin object, a bounding line or structure of a geometric figure or shape, and the like. (search "side" on Merriam-Webster.com. Merriam-Webster, 2021. Web. 03 Aug. 2021. Modified.) A side can also refer to a geometric edge of a polygon (two-dimensional shape) and/or a face or surface of a polyhedron (three-dimensional shape). (Search "side" on Wikipedia.com July 21, 2021. CC-BY-SA 3.0 Modified. Accessed Aug. 03, 2021.) Side can also refer to a location on a structure. For example, a side can be a location on a structure at, or near, a furthest position away from a central axis of the structure. As used herein, the term “side” can include one or more modifiers that define and/or orient and/or distinguish the side of an object from others based on based on where and/or how the object is deployed within or in relation to a second object. For example, in the context of an implant for a patient, sides of the implant may be labeled based on where the sides are relative to the patient when the implant is deployed. As one example, an “anterior side” of an implant, instrument, anatomical structure, or other structure refers to a side that is anterior to other sides of the structure in relation to a patient when the structure is deployed in the patient. As another example, in the context of an instrument used with a patient, sides of the instrument may be labeled based on where the sides are when the instrument is being used for its purpose. As one example, a “front side” of an instrument refers to a side that is facing a user of the instrument when the instrument is in use. |

In the illustrated embodiment, the tendon trajectory guide 1120 can include a bone engagement surface 1126 on at least part of the inferior side 1146 of the body 1134 of the tendon trajectory guide 1120. In one embodiment, the bone engagement surface 1126 can be defined at least in part based on a bone model of a bone that the inferior side 1146 will face and/or contact during use. In certain embodiments, this means that the bone engagement surface 1126 can include a mirror image of the surface of the bone of the patient in this area of the bone. Alternatively, or in addition, a tendon trajectory guide 1120 can be formed with an inferior side 1146 that lacks a bone engagement surface 1126 and instead can include a concave shape on the inferior side 1146 to accommodate a surface of a bone that the inferior side 1146 will face and/or contact during use. |
