Abstract

An orthopaedic joint replacement system is shown and described. The system includes a number of prosthetic components configured to be implanted into a patient's knee. The system also includes a number of surgical instruments configured for use in preparing the bones of the patient's knee to receive the implants. A number of methods for using the surgical instruments to prepare the bones is also disclosed.

Claims (26)

1 . An orthopaedic knee implant, comprising:

a modular tibial cone augment configured to be implanted into a surgically-prepared cavity in a proximal end of a tibia of a patient, the modular tibial cone augment comprising:

a central lobe component having: (i) a round elongated body, (ii) a bore configured to receive a stem of a revision tibial prosthesis extending through the elongated body, (iii) a medial connector comprising a tapered slot formed in an outer surface of a medial side of the elongated body, a superior end of the tapered slot of the medial connector opens into a superior end of the elongated body with the slot's opposite inferior end located between the superior end and an inferior end of the elongated body, and (iv) a lateral connector comprising a tapered slot formed in an outer surface of a lateral side of the elongated body, a superior end of the tapered slot of the lateral connector opens into the superior end of the elongated body with the slot's opposite inferior end located between the superior end and the inferior end of the elongated body,

a medial lobe component having: (i) a body having a curved medial outer surface that tapers from a superior end surface of the medial lobe component to an inferior end surface of the medial lobe component, (ii) a curved inner sidewall that corresponds in shape to the medial side of the elongated body of the central lobe component such that the curved inner sidewall abuts an outer surface of the medial side of the elongated body of the central lobe component from the superior end surface of the medial lobe component to the inferior end surface of the medial lobe component and, and (iii) a medial connector comprising a tapered tab formed in and extending outwardly from the curved inner sidewall which mates with the tapered slot of the medial connector of the central lobe component so as to selectively lock the medial lobe component to the central lobe component, a superior end of the tapered tab of the medial component is formed in the superior end surface of the body of the medial lobe component with the tab's opposite distal end located between the superior end surface and the inferior end surface of the body of the medial lobe component, and

a lateral lobe component having: (i) a body having a curved lateral outer surface that tapers from a superior end surface of the medial lobe component to an inferior end surface of the medial lobe component, (ii) a curved inner sidewall that corresponds in shape to the lateral side of the elongated body of the central lobe component such that the curved inner sidewall abuts an outer surface of the lateral side of the elongated body of the central lobe component from the superior end surface of the lateral lobe component to the inferior end surface of the lateral lobe component, and (iii) a lateral connector comprising a tapered tab formed in and extending outwardly from the curved inner sidewall which mates with the lateral connector of the central lobe component so as to selectively lock the lateral lobe component to the central lobe component, a superior end of the tapered tab of the lateral component is formed in the superior end surface of the body of the lateral lobe component with the tab's opposite distal end located between the superior end and the inferior end surface of the body of the lateral lobe component.

2 . The orthopaedic implant of claim 1 , wherein the medial connector of the central lobe component and the medial connector of the medial lobe component define a dovetail joint.

3 . The orthopaedic implant of claim 1 , wherein the lateral connector of the central lobe component and the lateral connector of the lateral lobe component define a dovetail joint.

4 . The orthopaedic implant of claim 1 , wherein a porous-metal coating is disposed on each of: (i) an outer surface of the elongated body of the central lobe component, (ii) the curved medial outer surface of the medial lobe component, and (iii) the curved lateral outer surface of the lateral lobe component.

5 . The orthopaedic implant of claim 1 , wherein:

the bore of the central lobe component is defined by a conically-shaped sidewall extending through the elongated body of the central lobe component, and

the conically-shaped sidewall has a number cement pockets formed therein.

6 . An orthopaedic knee implant, comprising:

a modular tibial cone augment configured to be implanted into a surgically-prepared cavity in a proximal end of a tibia of a patient, the modular tibial cone augment comprising:

a central lobe component having: (i) a round elongated body, (ii) a bore configured to receive a stem of a revision tibial prosthesis extending through the elongated body, and (iii) a connector comprising a tapered slot formed in an outer surface of a side of the elongated body, a superior end of the tapered slot opens into a superior end of the elongated body with the slot's opposite inferior end located between the superior end and an inferior end of the elongated body,

a side lobe component having: (i) a body having a curved outer surface that tapers from a superior end surface of the side lobe component to an inferior end surface of the side lobe component, (ii) a curved inner sidewall that corresponds in shape to the side of the elongated body of the central lobe component such that the curved inner sidewall abuts the curved outer surface of the body of the central lobe component from the superior end surface of the side lobe component to the inferior end surface of the side lobe component, and (iii) a connector comprising a tapered tab formed in and extending outwardly from the curved inner sidewall which mates with the tapered slot of the connector of the central lobe component so as to selectively lock the side lobe component to the central lobe component, a superior end of the tapered tab is formed in the superior end surface of the body of the side lobe component with the tab's opposite distal end located between the superior end and the inferior end surface of the body of the side lobe component.

7 . The orthopaedic implant of claim 6 , wherein the connector of the central lobe component and the connector of the side lobe component define a dovetail joint.

8 . The orthopaedic implant of claim 6 , wherein:

the side lobe component comprises a medial lobe component, and

the connector of the central lobe component is formed in a medial side of the elongated body.

9 . The orthopaedic implant of claim 6 , wherein:

the side lobe component comprises a lateral lobe component, and

the connector of the central lobe component is formed in a lateral side of the elongated body.

10 . The orthopaedic implant of claim 6 , wherein a porous-metal coating is disposed on each of: (i) an outer surface of the elongated body of the central lobe component, and (ii) the curved outer surface of the side lobe component.

11 . The orthopaedic implant of claim 6 , wherein:

the bore of the central lobe component is defined by a conically-shaped sidewall extending through the elongated body of the central lobe component, and

the conically-shaped sidewall has a number cement pockets formed therein.
