Abstract: An implant resection system for preparing an implant site to replace a defect in an articular surface of a first bone includes a guide configured to be coupled generally perpendicular to the first bone proximate to the defect. The guide includes a body portion defining a plurality of excision passageways. The excision passageways each define a generally cylindrical core pathway configured to extend generally perpendicular to the first bone which partially overlaps with an adjacent generally cylindrical core pathway. A projection associated with each of the plurality of the generally cylindrical core pathways defines a truncated cylindrical excision site extending through a portion of the articular surface. Each truncated cylindrical excision site partially overlaps with at least one adjacent truncated cylindrical excision site.

Abstract: Embodiments of devices, apparatuses, kits, and methods for repairing a human joint by suturing biological tissue to the articular surface of a bone at the joint (e.g., repairing defects in the humerus at the glenoid joint after an anterior shoulder dislocation) are described herein. Biological tissue may include hard tissue such as bone or a joint socket or soft tissue such as cartilage, ligaments, tendons, or muscle tissue.

Abstract: Microfracture apparatuses with a cannula and a penetrator. The cannula has a first end, a second end, and a channel extending between the first end and the second end through which a penetrator can move between a retracted and an extended position substantially without rotation of the penetrator. The cannula has a primary portion and a distal portion between the primary portion and the second end, with the distal portion configured such that the distal portion and/or the second end of the channel is disposed at a nonparallel angle relative to the primary portion, for example, with a curve between the primary portion and the distal portion. The penetrator is configured to flex around such a curve and/or to flex to align with the angle of the send end of the channel and/or the distal portion of the cannula.

Abstract: Apparatuses and methods for microfracture (e.g., forming a plurality of microfractures in a bone to encourage cartilage regeneration). Some of the present apparatuses and methods are configured to create microfractures with smaller transverse dimensions (e.g., diameters) and greater depths than previously known. Some of the present apparatuses and methods comprise a penetrator removal tab coupled to the penetrator and configured to retract the penetrator relative to the cannula.

Abstract: This disclosure includes apparatuses for simultaneous delivery of a fastener and an implant; systems including at least one of the present apparatuses, a seal assembly, and a cannula; caddy systems configured to receive a fastener and/or an implant for use with the present apparatuses; kits including at least one of the present apparatuses or systems and at least one of the present caddies; and methods of simultaneously delivering a fastener and an implant with the present apparatuses. The present apparatuses include an elongated body, one or more spikes at a body distal end of the body, a hub configured to receive a proximal portion of the body, and a handle coupled to the hub. The body defining a body recess in a peripheral surface of the body at point that is offset from the body distal end, and a body passage extending between a body proximal end and a body distal opening within the body recess. The apparatus further includes an elongated pusher and a slider coupled to a proximal end of the pusher, the slider configured to move longitudinally relative to the handle from a retracted position to a deployed position to move the pusher distal end longitudinally away from the body distal opening and laterally outward from the body.
