Abstract

The present invention provides a modular device for restoring individual joint kinematics using minimally invasive surgical procedures. The modular implants include distinct components that include interconnection means. The modular implants provide intraoperative surgical options for articular constraint and facilitate proper alignment and orientation of the joint to restore kinematics as defined by the individual patient anatomy.

Claims (33)

1 .- 8 . (canceled)

9 . A method of configuring a prosthesis system comprising:

selecting at least one first component in the prosthesis system for replacing a first surface portion of a bone, said at least one first component including a bone contacting side configured to be placed against the bone;

selecting at least one second component in the prosthesis system for replacing a second surface portion of the bone; and

connecting the selected at least one first component to the selected at least one second component with a first at least one resilient connector, the first at least one resilient connector formed from a material other than material used to form the second component.

10 . The method of claim 9 , wherein the step of connecting is performed ex vivo.

11 . The method of claim 9 , further comprising:

selecting at least one third component in the prosthesis system for replacing a third surface portion of the bone; and

connecting the selected at least one third component to the selected at least one first component with a second at least one resilient connector.

12 . The method of claim 11 , wherein connecting the selected at least one first component comprises selecting the first at least one resilient connector from at least two resilient connectors in the system, each of the two resilient connectors comprising a spacer.

13 . The method of claim 9 , wherein selecting a first component comprises selecting a first patellofemoral joint component for replacing a first surface portion of a patellofemoral joint; and selecting the second component comprises selecting a second patellofemoral joint component for replacing a second surface portion of the patellofemoral joint.

14 . A method for implanting a prosthesis system comprising:

making an incision;

selecting a first component having a bone mounting surface, a bone surface replacement surface, a first side adjacent to the bone mounting surface and adjacent to the bone surface replacement surface, and a second side adjacent to the bone mounting surface and adjacent to the bone surface replacement surface;

selecting a second component having a bone mounting surface, a bone surface replacement surface, and a side adjacent to the bone mounting surface and the bone surface replacement surface;

connecting the first component and the second component with a resilient connector, the resilient connector of a material different from material included in the second component such that the first side of the first component is in opposition to the side of the second component;

inserting the connected first component and second component through the incision; and

mounting the first and the second component on a bone such that the bone mounting surface of the first component and the bone mounting surface of the second component are in opposition to the bone.

15 . The method of claim 14 , wherein mounting the first and the second components comprises:

mounting the connected first and second components on the bone such that the first component replaces a portion of a patellofemoral compartment and the second component replaces a portion of a condylar compartment.

16 . The method of claim 14 , further comprising:

selecting a third component having a bone mounting surface, a bone surface replacement surface, and a side adjacent to the bone mounting surface and the bone surface replacement surface; and

connecting the third component with the first component and the second component such that the side of the third component is in opposition to the second side of the first component, and wherein inserting comprises, inserting the connected first component and second component and third component through the incision, and

wherein mounting comprises, mounting the first, the second and the third component on a bone such that the bone mounting surface of the first component and the bone mounting surface of the second component and the bone mounting surface of the third component are in opposition to the bone.

17 . The method of claim 16 , wherein mounting comprises:

mounting the connected first, second and third components on the bone such that the first component replaces a portion of a patellofemoral compartment, the second component replaces a portion of a first condylar compartment, and the third component replaces a portion of a second condylar compartment.

18 . The method of claim 14 , further comprising:

selecting the resilient connector; and

connecting the first component to the resilient connector; and

connecting the second component to the resilient connector.

19 . (canceled)

20 . The method of claim 14 , wherein connecting comprises:

connecting the first component and the second component with a resilient connector integrally formed with the first component.
