Abstract: An orthopaedic knee prosthesis includes a femoral component having a condyle surface. The condyle surface is defined by one or more radii of curvatures, which are controlled to reduce or delay the onset of anterior translation of the femoral component relative to a tibial bearing.

Abstract: A modified system for assessing tension intraoperatively during joint arthroplasty includes a discrete sensor array, protector and trial. The protector is mechanically connected to the joint trial and covers the sensor array to protect it from wear. The sensor array can be positively located to prevent it from moving during use. In assembly of the modified system, the sensor array and protector are sterilized as discrete elements. After sterilization, the protector is removably attached to one of the trials with the sensor array substantially covered by the protector to protect the sensor from wear.

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.

Abstract: The present invention provides a halogen coated biomedical device and a method for producing the device. The method generally involves generating a plasma that affects the release of a halogen species from a source. The halogen reacts with the surface of the biomedical device to form a halogen coating.

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: According to one embodiment of the present invention, there is provided a joint prosthesis (10) having a first component (12) for cooperation with a first long bone (14) and a second component (16) for cooperation with a second long bone (20). The joint prosthesis (10) further includes a bearing component (22) positionable between the first component (12) and the second component (16) and cooperable with the first component (12) and the second component (16). The bearing component (22) includes a reinforcing component (36) having a first portion (54) defining a first centerline (50) and having a second portion (56) defining a second centerline (52). The first centerline (50) and the second centerline (52) are non-coincidental. The bearing component (22) includes a polymeric material (112) surrounding the reinforcing component (36) and molded to the reinforcing component (36).

Abstract: A tibial trial assembly for evaluating the stability and kinematics of a tibial implant, particularly a mobile bearing implant, prior to committing to the final preparation of the proximal tibia is described. The tibial trail assembly includes a tray trial adapted to be secured onto a resected proximal end of a patient's tibia. An evaluation bullet is either adapted to removably fit into a configured recess in the trial tray, or is integral therewith. A trunnion on the evaluation bullet accepts a recess in a corresponding articular tibial insert trial. The tibial insert trial is thus received on the trunnion. Preferably, the evaluation bullet is removable from the trial tray such that the remaining assembly is used to locate and guide (orient) the instrument(s) that prepare the tibia for the final implant. Typically, this includes broaching, drilling, or punching through the opening in the trial tray/plate.

Abstract: A method of manufacturing a bearing component for use in arthroplasty for cooperation with a first and a second component includes the step of providing a non-linear support of a durable material having. The method further includes providing a molding die for manufacturing the bearing component having first and second mold portions. The first mold portion provides a first surface for cooperation with the first joint component and the second mold portion provides a second surface for cooperation with the second joint component. The method includes positioning the support in a desired position within the molding die with the first end or the second end located in the first mold portion, adding moldable material into the molding die, surrounding the support with the moldable material, heating and pressurizing the moldable material, permitting the moldable material to cool, and removing the component from the molding die.
