  • Publication number: 20130158556
    Abstract: Tools or other instruments can be used by a surgeon to complete an orthopedic procedure. One tool can include a resection tower and a valgus guide. The resection tower can include a cutting block and a dial coupled with the cutting block. The resection tower can be configured such that rotational movement of the dial, about an axis, effectuates movement of the cutting block along a plane substantially parallel with the axis. The dial, when rotated in a first direction, can move between a first position, which corresponds to a minimum cutting depth of the cutting block, and a second position, which corresponds to a maximum cutting depth of the cutting block. The valgus guide can be coupled with the resection tower and includes a rotatable member. The rotatable member can include an angular surface with one or more variable depth splines providing varus/valgus angle adjustment of the cutting block.

  • Publication number: 20130018382
    Abstract: A femoral component instrument includes a rotatable locking mechanism such as a post and is capable of interchangeable use between posterior stabilizing (“PS”) and cruciate retaining (“CR”) femoral component types via the locking mechanism. The instrument further includes a modular pad so that a pad specific to the prosthesis type may be chosen. Each pad of a particular femoral component type is useable with a variety of sizes of that femoral component type. The locking mechanism of the instrument is alternatively useable with a variety of femoral component types. The locking end of the post keys to a pad aperture to rotatably align the post to an appropriate securement position. If a femoral component is not locked to the pad, the post of the instrument moves from an exposed position proximal to the proximal pad surface to a retracted position distal to the proximal pad surface, thereby permitting impaction.

  • Publication number: 20120323334
    Abstract: A provisional femoral component, in one embodiment, including at least one first visual indicator and at least one second visual indicator, the first and second visual indicators providing indicating means for simultaneously visually representing a first profile of a first femoral prosthesis and a second profile of a second femoral prosthesis. In another embodiment, a provisional femoral component including a patellofemoral flange having two sulci and a central ridge between the two sulci. In this manner, the provisional femoral component can be positioned on a resected distal femur surface of both a right and left knee joint.

  • Publication number: 20120101504
    Abstract: An extramedullary cut guide alignment assembly allows various adjustments to the cut guide without introducing bending stresses in the rest of the assembly. More particularly, the angular orientation of the cut guide with respect to the tibia may be freely changed during use, while maintaining the angular orientation of the proximal fixation arm of the alignment assembly with respect to the proximal tibial surface to which the arm is affixed. To achieve this decoupling of the angular orientations of the fixation arm and cut guide, the proximal fixation arm is pivotably mounted to the cut guide alignment assembly. Thus, the alignment assembly may be adjusted as necessary to achieve a desired angular orientation of the cut guide mounted thereto, while the pivotable junction between the alignment assembly and the proximal fixation arm automatically adjusts to accommodate the changing angular arrangement.

  • Publication number: 20120035737
    Abstract: A tibial prosthesis has a bearing component configured for an anterior-medial insertion, which advantageously avoids the extensor mechanism of the knee. A tibial tray may include a banana-shaped boss that corresponds to a notch formed in the bearing component. After the bearing component is inserted along the anterior-medial path, the boss is received within the notch by rotating the bearing component with respect to the tibial tray. This rotation seat the bearing component upon the tibial tray in the manner of a fixed-bearing prosthesis. Alternatively, the boss and notch may define angled central axes which allow straight anterior-medial insertion of the bearing component and locking engagement to the tibial tray.

  • Patent number: 6017306
    Abstract: The invention is directed to an orthopaedic retractor frame assembly (10) for use during orthopaedic surgery at an incision site associated with a limb of a patient. The retractor frame assembly (10) includes a retractor frame (16) for placement adjacent the incision site. A limb attachment device (22) is connected to the retractor frame (16) and is configured for connection with a limb of the patient, whereby the retractor frame (16) is held at a desired orientation relative to the incision site. In addition, the retractor frame assembly (10) provides for retractor instruments (18) to be adjustably positioned relative to the retractor frame (16).
