  • Publication number: 20220054274
    Abstract: A implant delivery system for securing an implant to an anchor. The implant delivery system includes a driver including a shaft, a biasing body having a first end region configured to engage said driver and a second end region configured to engage a portion of an implant, and a suture extending between the anchor and the shaft of the driver. The driver may be rotated to reduce the length of the suture between the driver and the anchor and generate a biasing force urging the implant into engagement with the anchor. The biasing force is substantially not transmitted to the bone.

  • Publication number: 20210145483
    Abstract: A suture system including a suture construct having a first reduction construct configured to be selectively arranged in an expanded state and a reduced state. The first reduction construct includes a first locking limb, a first contractible loop, and a first opposed loop disposed generally opposite to the first contractible loop, wherein reduction of the first opposed loop contracts the first contractible loop from the expanded state into the reduced state and secures the suture construct in the reduced state. The suture construct may also include a second reduction construct. Optionally, the suture system includes a first and a second pusher tube defining a first and a second lumen, respectively, wherein each pusher tubes are advanced over portions of opposed loops, respectively, and wherein distal portions of opposed loops extend beyond the pusher tubes, respectively.

  • Publication number: 20210038398
    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.
