View Edit Delete	VIL-12	An improved joint implant apparatus, system, and method. The system includes an implant having a bone-facing articular surface configured to replace at least part of a natural articular surface of a bone adjacent to a joint. The system also includes a transosseous coupler and a bone anchor configured to reside proximate another surface of the bone, separated from the natural articular surface by a bone tunnel. The bone anchor is configured to couple the transosseous coupler to the bone such that the transosseous coupler retains the implant in place on the natural articular surface of the bone.	207	Added by DJM 2 2022	2/5/22, 12:00 AM

View Edit Delete	VIL-12	Many patients suffer with joint pain and/or reduced joint kinematics. Various conditions may affect skeletal joints such as the injury, disease, deterioration, elongation, shortening, or rupture of soft tissues, cartilage, and/or bone associated with the joint and consequent laxity, pain, loss of movement, and/or deformity. Such conditions can adversely impact the daily activities of the patient.	2	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	The medical industry uses a variety of procedures to address these conditions, including: various osteotomy procedures, joint fusion procedures, fracture fixation procedures, joint resurfacing procedures, implants, joint spacers, and the like. Such procedures can be performed throughout the body and on various joints of the body.	3	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	However, these procedures, devices, and/or system have limitations. For example, certain procedures may remove a high percentage of bone of an articular surface of the joint. Other procedures may fuse the joint which may address pain but can limit mobility and activity of the patient. Other procedures and/or prosthesis may be prone to periprosthetic fractures and/or prosthetic dislocation.	4	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	Accordingly, a need exists for an improved joint implant apparatus, system, and method that removes minimal bone material, mechanically secures the implant, secures the implant with an adjustable level of tension, enables natural movement of the joint, and provides adjunctive fixation.	5	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	The various apparatus, devices, systems, and/or methods of the present disclosure have been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently arthroplasty and/or implants. One general aspect of the present disclosure can include an implant having a joint-facing articular surface configured to replace at least part of a natural articular surface of a bone adjacent to a joint, and a transosseous coupler. The system may include a bone anchor configured to reside proximate another surface of the bone. The bone anchor can be separated from the natural articular surface by a bone tunnel. The system may include a transosseous coupler configured to couple the implant to the bone anchor and the bone anchor may be configured to couple the transosseous coupler to the bone such that the transosseous coupler retains the implant in place on the natural articular surface of the bone.	6	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	Implementations may include one or more of the following features. The system in which the transosseous coupler applies tension on the implant, where the tension holds the joint-facing articular surface in place on a distal end of the bone. A first diameter of the joint-facing articular surface is smaller than a second diameter of the natural articular surface of the bone. A first diameter of the joint-facing articular surface is greater than a width of an osteochondral lesion (OCL) of the natural articular surface and smaller than a second diameter of the natural articular surface of the bone. The system may include an implant that may include a body having a joint-facing articular surface, a convex posterior surface, and an edge between the joint-facing articular surface and the convex posterior surface. The bone tunnel may include a distal end and a proximal end and the proximal end exits between a distal end of the bone and a proximal end of the bone; and the distal end of the bone tunnel exits within a bone pocket that extends proximally from the natural articular surface into the bone. The implant may be coupled to the bone anchor by a transosseous coupler. A body of the implant may seat within the bone pocket with the edge extending above the natural articular surface of the bone. The joint-facing articular surface may be convex and a top of the joint-facing articular surface may be congruent with cartilage around the implant. The joint-facing articular surface may be convex with the edge being circular. The convex posterior surface may have an implant radius greater than a bone radius of the bone pocket. The transosseous coupler may include a tether configured to engage with a first connector coupled to the implant and configured to engage with a second connector coupled to the bone anchor.	7	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	One general aspect of the present disclosure can include an arthroplasty implant configured to engage a distal articular surface of a metatarsal bone; a bone anchor secured to the metatarsal bone away from the distal articular surface, and a tether configured to couple the arthroplasty implant and the bone anchor.	8	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	Implementations may include one or more of the following features. The arthroplasty implant system may include an arthroplasty implant that may include: an articular implant where the articular implant is embedded within a bone pocket of the distal articular surface when the tether couples the articular implant to the bone anchor such that bone pocket retains the articular implant in place during osseointegration of the articular implant to the metatarsal bone. The arthroplasty implant may include a spacer configured to maintain separation between the distal articular surface and an articular surface of an adjacent phalanx bone. The arthroplasty implant may include: a body having a joint-facing articular surface and a convex posterior surface configured to engage the distal articular surface by way of a bone pocket formed within the distal articular surface; an edge between the joint-facing articular surface and the convex posterior surface; and a connector configured to engage with the tether and secure the arthroplasty implant to the tether.	9	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	The tether couples the arthroplasty implant to the bone anchor through a bone tunnel that extends from the bone pocket such that when the tether couples the arthroplasty implant to the bone anchor at least a portion of the edge contacts a surface of the bone pocket below the distal articular surface. The bone tunnel may include a proximal opening near a dorsal surface of the metatarsal bone. The bone anchor sits within the bone tunnel and within the proximal opening and the bone anchor may include: a cylindrical body may include an opening that extends from one end of the cylindrical body to the other end and external threads on an outside surface of the cylindrical body, the external threads configured to engage an internal surface of the bone tunnel, and a tether locking feature configured to sit within the opening of the cylindrical body and couple a proximal end of the tether to the bone anchor. The arthroplasty implant may seat within the bone pocket such that a top of the joint-facing articular surface is congruent with or below a surface of surrounding cartilage of the distal articular surface and the edge is below the surface of surrounding cartilage when the tether couples the arthroplasty implant to the bone anchor.	10	Added by DJM 2 2022	2/5/22, 12:00 AM
