  • Patent number: 10130375
    Abstract: Methods and instruments for performing a kinematically-aligned total knee arthroplasty (TKA) are disclosed. Goals of the kinematically-aligned TKA can include restoration of (1) the femoral and tibial joint lines to the patient's natural joint line, (2) the patient's Hip-Knee-Ankle alignment to their constitutional alignment prior to developing osteoarthritis and (3) restoration of the patient's natural soft tissue laxity and envelope. A shim block assembly can be used in resecting the distal medial and lateral condyles to account for cartilage wear on the distal condyles from osteoarthritis. The shim block assembly can include a plurality of shims, and each shim can be attachable to or integral with a reference block. At least one of the plurality of shims can have a medial portion with a thickness different from a thickness of a lateral portion of the shim. The shims need not be joined together as a single medial/lateral component but may be independent of one another.

  • Patent number: 10092418
    Abstract: A tooling system and method is disclosed for removing a head portion of a modular implant from a stem portion of the implant. The tooling system can include first and second tools configured to releasably mate together when the upper and lower tools are in an assembled position, and a holder configured to releasably secure the first and second tools in the assembled position. The first and second tools can be inserted between the head portion and an adaptor of the stem portion. When the first and second tools are rotated in opposite directions, the first tool can exert pressure on the head portion of the implant sufficient to release the head portion from locked engagement with the adaptor. The first and second tools can include mating features that disengage from each other as the tools are rotated in opposite directions.

  • Patent number: 10085732
    Abstract: Systems, devices, and methods suitable for use with procedures performed at least partially percutaneously are provided. In some procedures, two or more access devices for providing access to adjacent surgical locations within a patient are used. Certain embodiments of the access device comprise an elongate body having a distal end with one or more cutouts. The cutouts on adjacent access devices are generally aligned with each other to permit passage of a portion of a fixation element from one access device to the other access device. A fastener with an elongated removable head may be delivered to the surgical site through the access device. After a distal end of the fastener is secured to the surgical site, a portion of the elongated housing is detached from the remainder of the fastener and removed from the patient.

  • Patent number: 10076420
    Abstract: In an orthopedic knee joint prosthesis, an intercondylar fossa of a femoral component cooperates with a spine formed in a tibial component to reproduce the screw home mechanism of a natural knee. When the femoral component and tibial component are positioned to correspond with slight flexion of the knee, the components are mutually rotationally locked against internal or external rotation. At higher degrees of flexion, such as greater than about 10-20 degrees of flexion, internal/external rotation of the tibia is permitted. The tibia is in an externally rotated position when locked, thereby reproducing the screw home mechanism and providing high stability.
