1. A method for designing an implant for repairing a joint of a patient comprising the following steps:
- obtaining data for the joint;
fusing at least two imaging planes from the image data for the joint;
segmenting image data of one or more meniscal surfaces of the joint; and
converting the segmented image data into a patient-specific surface of the implant.

Abstract
The present invention relates to methods for determining meniscal size and shape for use in designing therapies for the treatment of various joint diseases. The invention uses an image of a joint that is processed for analysis. Analysis can include, for example, generating a thickness map, a cartilage curve, or a point cloud. This information is used to determine the extent of the cartilage defect or damage and to design an appropriate therapy, including, for example, an implant. Adjustments to the designed therapy are made to account for the materials used.
