Abstract: One aspect of the present disclosure can include a biocompatible tissue graft. The graft can include an extracellular matrix (ECM) patch or strip and at least one fiber stitched into the ECM patch or strip in a peripheral reinforcement pattern. The at least one fiber can have opposing terminal ends. The at least one fiber can mitigate tearing and/or improve fixation retention of the ECM patch or strip. The at least one fiber can comprise a plurality of interconnected stitches. The opposing terminal ends of the at least one fiber can be stitched together to form a continuous stitching construction.

Abstract: A biocompatible tissue graft is provided. The tissue graft includes an extracellular matrix patch and a means for reinforcing the patch.

Abstract: An insert component includes an insert body and a cavity defined within the insert body. The insert body includes a first surface, a second surface spaced from the first surface, and a third surface. The second surface cooperates with the first surface to define at least one first channel configured to receive an engagement member. The third surface has a first and second surface end each extending from a perimeter of the first surface. A curved portion of the third surface between the first surface end and the second surface end extends into the insert body. The cavity includes a first cavity opening defined by the first surface. The cavity defines a first cavity region and a second cavity region each coextensive with a third cavity region. The first cavity region and second cavity region each have a cavity diameter greater than a diameter of a plate engagement member.

Abstract: A guide for placing a landmark(s) in a patient tissue comprises a central portion defining at least one guiding bore configured to receive and guide a tool for placing the at least one landmark in the patient tissue. Extended portions project away from the central portion, each of the extended portions having respective lower base surfaces contoured to mate with the patient tissue, at least the respective lower base surfaces being customized as a function of preoperative imaging of the patient tissue, whereby the guide is specific to the patient.

Abstract: A method of performing joint arthroplasty includes accessing a surface on a bone and supporting a stop with the accessed surface. The method includes positioning an instrument at least partially within the stop, the instrument having a body and a punch, the punch including a portion thereof having a shape similar to a shape of a stem of an implant, and rotating the stop with respect to the accessed surface based upon an indicia on one of the body and the stop so as to position the punch rotationally with respect to the accessed surface at a first orientation. The method further includes moving the body axially with respect to the stop to form a cavity in the bone with the punch at the first rotational orientation, the formed cavity having a shape similar to the stem of the implant, and implanting the stem of the implant into the cavity.

Abstract: A method of performing joint arthroplasty includes preparing a flat surface on a long bone, providing an instrument having a body and a punch extending from the body, the punch including a portion thereof having a shape similar to a stem of an implant, positioning a stop on the flat surface, rotating the stop with respect to the surface of the long bone based upon an indicia on one of the body and the stop so as to position the punch rotationally with respect to the surface to a desired orientation when the instrument is at least partially inserted into the stop, using the instrument to form a cavity in the long bone with the punch at the desired rotational orientation with the instrument inserted at least partially within the stop, the cavity having a shape similar to the stem of the implant, and implanting the stem into the cavity.

Abstract: A stock instrument includes at least one guide interacting feature. A lower instrument surface of the stock instrument is placed into contact with the patient tissue. A guide has a lower guide surface contoured to substantially mate with at least a portion of an upper instrument surface of the stock instrument. A predetermined instrument orientation upon the patient tissue is defined, which is preselected responsive to preoperative imaging of the patient tissue. The guide and instrument are mated in a predetermined relative guide/instrument orientation wherein at least one guide interacting feature of the instrument is placed into engagement with at least one instrument guiding feature of the guide. The guide is moved into a predetermined guide orientation with respect to the patient tissue and concurrently the instrument is moved into a predetermined instrument orientation with respect to the patient tissue.

Abstract: A method for aligning a manipulable sensor assembly includes determination of a replica surface, which represents a field of view of a manipulable sensor assembly associated with an object when the object is located in a desired position and oriented at a desired orientation. Electromagnetic radiation and/or sound reflected from a surface of the region of interest is detected to provide a surface map of the region of interest, which is compared to the replica surface to determine a rotation and/or a translation for the manipulable sensor assembly to bring the surface map into alignment with the replica surface. The position and/or the orientation of the object are altered. The detection of reflected electromagnetic radiation or sound, comparison of the surfaces, and alteration of the position and orientation of the object are repeated until the surface map is in alignment with the replica surface.
