## Abstract

Provided herein are 3D-printed patient-specific surgical guides and methods for making and using the same. In at least one embodiment, the guides include a first and second end, a first and second side, a conformal bone engaging surface, a front surface, one or more porous regions, one or more walls, and a plurality of openings. At least one of the plurality of openings extends through the guide between the conformal bone engaging surface and the front surface. The conformal bone engaging surface is contoured to a patient's anatomy. The first and second end, and the first and second side are contoured to avoid soft tissues of the patient.

## Claims

### Claim 1

A patient-specific surgical guide comprising:
a body comprising:
a metallic material;
a front surface;
a conformal tissue engaging surface opposite the front surface and contoured to a patient's anatomy; and
an opening extending through the body between the conformal tissue engaging surface and the front surface and sized to receive a surgical tool for preparing a portion of the patient's anatomy, wherein the conformal tissue engaging surface comprises one or more porous structure regions and at least one of the one or more porous structure regions has an effective radius of 0.5 mm to 1 mm.

### Claim 2 (depends on 1)

The patient-specific surgical guide of claim 1, wherein the one or more porous structure regions comprise a gyroid structure.

### Claim 3 (depends on 1)

The patient-specific surgical guide of claim 1, wherein:
the body comprises a first end, a second end, a first side, and a second side; and
the first end, the second end, the first side, and the second side are contoured not to engage at least one soft tissue structure of the patient's anatomy.

### Claim 4 (depends on 1)

The patient-specific surgical guide of claim 1, wherein the conformal tissue engaging surface is a conformal bone engaging surface.

### Claim 5

A patient-specific surgical guide comprising:
a body comprising:
a metallic material;
a front surface;
a conformal tissue engaging surface opposite the front surface and contoured to a patient's anatomy, wherein the conformal tissue engaging surface comprises one or more textured regions and at least one of the one or more textured regions has a minimum feature size of 0.1 mm to 2 mm; and
an opening extending through the body between the conformal tissue engaging surface and the front surface.

### Claim 6 (depends on 5)

The patient-specific surgical guide of claim 5, wherein the one or more textured regions comprise a porous structure.

### Claim 7 (depends on 5)

The patient-specific surgical guide of claim 5, wherein:
the body comprises a first end, a second end, a first side, and a second side; and
the first end, the second end, the first side, and the second side are contoured to avoid at least one soft tissue structure of the patient's anatomy.

### Claim 8 (depends on 5)

The patient-specific surgical guide of claim 5, wherein the body is a 3D-printed body.

### Claim 9

A system for performing a surgical procedure, the system comprising:
a patient-specific surgical guide comprising:
a metallic material;
a front surface opposite a conformal tissue engaging surface, wherein:
the conformal tissue engaging surface is contoured to patient anatomy and comprises one or more textured regions; and
at least one of the one or more textured regions has a minimum feature size of 0.1 mm to 2 mm; and
an opening extending through the patient-specific surgical guide between the conformal tissue engaging surface and the front surface and sized to receive a surgical tool; and
an implant.

### Claim 10 (depends on 9)

The system of claim 9, wherein the implant is a patient-specific implant.

### Claim 11 (depends on 9)

The system of claim 9, wherein the implant is an ankle implant.

### Claim 12 (depends on 9)

The system of claim 9, wherein the implant is a shoulder implant.

### Claim 13 (depends on 9)

The system of claim 9, wherein the implant is a hip implant.

### Claim 14 (depends on 9)

The system of claim 9, wherein the implant is a knee implant.
