Abstract: Methods and apparatus for planning and/or carrying out a total knee replacement surgical procedure on a knee of a leg of a patient are described. Anatomical data for the leg of the patient is obtained, which allows the femoral mechanical axis, the tibial mechanical axis, and the joint line of the knee to be determined. A planned proximal tibial cut angle and a planned distal femoral cut angle are determined. A total knee replacement procedure is carried out on the knee of the patient such that a distal femoral cut is made using the planned distal femoral cut angle and a proximal tibial cut is made using the planned proximal tibial cut angle.

Abstract: A femoral sizing instrument for use in a knee joint replacement procedure has a housing which includes formations by which it can be located relative to the femoral posterior condyles. A cortex arm has a tip for engaging the anterior cortex of the femur and a sulcus arm has a tip for engaging the sulcus. Each of the cortex and sulcus arms can be adjusted relative to the housing to adjust the distance between its tip and the posterior condyles measured generally parallel to the anterior posterior axis. The instrument includes at least one scale for indicating the positions of the tips of the cortex and sulcus arms relative to the posterior condyles.

Abstract: A tissue protector is adapted to be positioned on the skin surrounding an incision. The tissue protector provides a load bearing surface for surgical tools and instruments to prevent blunt force and pressure trauma to the skin and soft tissues within the incision. In one embodiment, the tissue protector is a sheet of wear-resistant material having an opening corresponding to the incision and expandable as the incision is retracted. In another embodiment, a tissue protector device includes a continuous expandable arrangement of interconnected L-shaped links. In still another embodiment, a one-piece tissue protector includes a flexible panel supported on the skin and a flexible sleeve extending into the incision. Yet another embodiment of the invention resides in a track that is supported about the incision. An instrument support platform is slidably mounted to the track to support a surgical tool relative to the incision.

Abstract: A femoral sizing instrument for use in a knee joint replacement procedure has a housing which includes formations (4) by which it can be located relative to the femoral posterior condyles. A cortex arm (14) has a tip (16) for engaging the anterior cortex of the femur and a sulcus arm (20) has a tip (24) for engaging the sulcus.

Abstract: A joint prosthesis has a first component for cooperation with a first long bone, a second component for cooperation with a second long bone, and a bearing component positionable between the first component and the second component. The bearing component includes a reinforcing component and a polymeric material completely encapsulating the reinforcing component and molded thereto. The bearing component may be sterilized by a predominately surface sterilizing technology.

Abstract: An orthopaedic implant is provided for the treatment of avascular necrosis of the bone. The orthopaedic implant includes a hollow support structure and a synthetic vascular graft. The support structure defines a passageway and includes a proximal opening and a distal opening. The synthetic vascular graft is received, at least in part, within the passageway such that a proximal end portion of the synthetic vascular graft is received through the proximal opening of the support structure and a distal end portion of the synthetic vascular graft is received through the distal opening of the support structure.

Abstract: A system for providing information related to an orthopaedic surgical procedure to a surgeon includes a user-worn computer coupled with a heads-up display. The user-worn computer and the heads-up display cooperate to display orthopaedic surgical information to the surgeon. The user-worn computer receives data from a first processing circuit and a second processing circuit. The first processing circuit determines navigational data based on data signals received from navigation sensors. The second processing circuit determines patient condition data based on data signals received from patient condition sensors. Additionally, the system may include one or more peripheral ports for receiving a removable memory device.
