Abstract: A patient-specific osteotomy guide according to the present disclosure includes a three-dimensional bone-engaging inner surface configured to closely mate and conform to a corresponding portion of a specific patient's tibia. A resection slot at a patient-specific position and orientation to guide a cutting tool to perform an osteotomy according to a preoperative plan for the patient. An axial guide at a patient-specific position and orientation to guide a tool to perform an ACL/PCL reconstructive procedure according to a preoperative plan for the patient.

Abstract: An alignment plate can be designed and formed based upon a known geometry of a subject, such as a human patient. The alignment plate can include various members, such as a plurality of fingers or legs, to contact the selected points of the anatomy. Based upon contact of the fingers at the selected points of the anatomy, the alignment plate can be aligned at a preselected or predetermined alignment with a portion of the anatomy, such as an acetabulum.

Abstract: An orthopedic device includes a patient-specific acetabular guide that may be used for preparing an acetabulum of a patient to receive an acetabular implant. The acetabular guide has a body with an outer three-dimensional surface configured to match an acetabulum of a specific patient's hip joint designed from data of the patient's hip joint. The acetabular guide may further include a peripheral annular rim.

Abstract: A glenoid device for preparing a shoulder joint of a patient includes a reusable guide holder having a body between an upper surface and a lower surface and a bore passing through the body of the guide holder. The glenoid device also includes a patient-specific glenoid guide having a body with an upper and lower surface. The lower surface of the patient-specific glenoid guide is configured as a negative surface of a glenoid face based on preoperative image scans of the shoulder joint of the patient. The upper face of the patient-specific glenoid guide is configured to be coupled and contact the lower face of the guide holder, such that the bore of the guide holder is aligned along a patient-specific bore through the body of the patient-specific glenoid guide and along a corresponding alignment axis of the patient-specific glenoid guide.
