## Abstract

Disclosed herein are methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.

## Claims

### Claim 1

A knee joint arthroplasty system for repairing a diseased or damaged knee joint of a patient, comprising:
one or more implant components; and
at least one patient-specific surgical tool which includes:
a block having a patient-specific surface and first and second drilling holes;
the patient-specific surface having at least a portion that is substantially a negative of a corresponding portion of a diseased or damaged articular surface of the knee joint of the patient and having a predetermined position and orientation relative to the corresponding portion;
the first and second drilling holes having predetermined positions and orientations relative to the patient-specific surface and each having an axis that extends through a portion of the joint when the patient-specific surface is fit to the corresponding portion of the diseased of damaged articular surface of the knee joint of the patient.

### Claim 2 (depends on 1)

The system of claim 1, wherein the one or more implant components include standard implant components.

### Claim 3 (depends on 1)

The system of claim 1, wherein the one or more implant components include customized implant components.
