1. A surgical system for use in surgically repairing a hip joint of a patient, comprising:
- a block having a patient-specific surface and a guide sized to accommodate a surgical tool;
wherein a first portion of the patient-specific surface has a shape that substantially matches a shape of an acetabular rim surface adjacent the hip joint and a second portion of the patient-specific surface that substantially matches a shape of a cartilage surface associated with the hip joint; and
wherein the guide has a position and orientation relative to the patient-specific surface to define a predetermined path for the surgical tool that is aligned through a portion of tissue associated with the hip joint when the patient-specific surface is placed against and aligned with the acetabular rim surface.

9. A surgical system for use in surgically repairing a hip joint of a patient, comprising:
a block having a patient-specific surface and a guide sized to accommodate a surgical tool; wherein the patient-specific surface is shaped based on image data of at least a portion of an acetabular rim of the hip joint of the patient; and wherein the guide has a position and orientation relative to the patient-specific surface to define a predetermined axis for a reaming tool that is aligned through a portion of the acetabulum of the hip joint when the patient-specific surface is placed against and aligned with the acetabular rim surface. - View Dependent Claims (10, 11, 12)
