  • Patent number: 10827971
    Abstract: A method of generating a correction plan for a knee of a patient includes obtaining a ratio of reference bone density to reference ligament tension in a reference population. A bone of the knee of the patient may be imaged. From the image of the bone, a first dataset may be determined including at least one site of ligament attachment and existing dwell points of a medial femoral condyle and lateral femoral condyle of the patient on a tibia of the patient. Desired positions of contact in three dimensions of the femoral condyles of the patient with the tibia of the patient may be obtained by determining a relationship in which a ratio of bone density to ligament tension of the patient is substantially equal to the ratio of reference bone density to reference ligament tension.

  • Patent number: 10709460
    Abstract: Disclosed herein are systems and methods for identifying the proper implant for use in an arthroplasty procedure and preparing a bone surface for the placement of such implant. In one embodiment, a centering guide system includes a cannulated post and a translucent surface trial where the cannulated post includes a slit defining legs that flex to engage the post when inserted in a hole of the surface trial. The system is used to confirm a suitable implant size and place a pilot wire in preparation for implant placement. The cannulated post and the translucent surface trial provide comprehensive visibility of the glenoid surface. When inserted into the surface trial, an extension of the cannulated post beyond an articulating surface of the surface trial is minimal or nonexistent. In this way, the congruence of a reamed glenoid surface can be evaluated prior to implantation of the implant.

  • Patent number: 10702258
    Abstract: A ratcheting inserter device for tensioning a knotless suture anchor includes an outer inserter shaft and an inner inserter shaft having a common longitudinal axis. A ratcheting mechanism provided between the inner inserter shaft and the outer inserter shaft permits rotation of the inner inserter shaft in one direction relative to the outer inserter shaft. The outer inserter shaft has a protrusion at a distal end that is received by an anchor outer sleeve of a suture anchor to prevent relative rotation thereof, and the inner inserter shaft has a projection at the distal end that is received by an inner core of the anchor for rotational movement therewith. The ratcheting inserter device rotates the inner core of the suture anchor to spool and tension suture thread. Thereafter, the ratcheting mechanism is disengaged and the inner inserter shaft is forced axially into the anchor outer sleeve.

  • Patent number: 10702397
    Abstract: An insertion handle for medical implants includes a handle with an elongate shaft extending therefrom and connection means for the implant disposed at the end of the shaft opposite the handle. The connection means includes a pivotable attachment for the implant that is controlled remotely from the handle. Both angle of the implant with respect to the handle and shaft as well as the attachment may be separately controlled and adjusted. Remote angular adjustment facilitates insertion of implants in to small surgical sites because the orientation of the implant may be repeatedly, remotely adjusted as the implant is inserted. Connectors may also be provided at the engagement surface between the handle and implant in order to provide communication with the implant or surgical site. The connectors also may serve as torque bearing members to avoid the need for separate torque bearing means such as keyways and the like.
