  • Methods and apparatuses for attaching tissue to orthopaedic implants
    Patent number: 9005305
    Abstract: Methods and apparatuses for attaching tissue structures to orthopaedic implants. In one exemplary embodiment, the methods and apparatuses are used to attach soft tissue and/or bone to a proximal tibial implant. In another exemplary embodiment, the methods and apparatuses are used to attach soft tissue and/or bone to a proximal femoral implant.

  • Orthopedic tool for altering the connection between orthopedic components
    Patent number: 8435244
    Abstract: An orthopedic tool for loosening the connection between orthopedic components. In one embodiment, the orthopedic tool includes a housing and a wedge. The housing has a head, an upper portion, a lower portion, and an opening between the upper and lower portions. The wedge is positioned at least partially between the upper portion and the lower portion of the housing and is actuatable to move toward the head of the housing. When at least a portion of the head of the housing is placed in mating engagement with the junction between two assembled orthopedic components, advancement of the wedge towards the head results in separation of the upper portion and lower portion of the housing. Thus, as the wedge is advanced toward the head, the upper and lower portions of the housing are separated, which results in corresponding separation of the assembled orthopedic components.
