An instrumentation set for preparing a proximal tibia during a bi-cruciate retaining procedure can include a tibial resection block and a stylus. The tibial resection block can be configured to be fixed to an anterior portion of the proximal tibia. The tibial resection block can define a slot that extends in a medial-lateral direction when the tibial resection block is fixed to the proximal tibia. The stylus can have a first block attachment feature and a second block attachment feature. The first block attachment feature can be offset from the stylus a first distance. The second block attachment feature can be offset from the stylus a second distance. The first and second block attachment features of the stylus can be selectively and alternatively received by the slot of the tibial resection block to position the stylus at distinct offset locations relative to the slot.

Bi-cruciate knee system

A method of preparing a knee joint for a prosthesis in a patient includes mating a patient-specific three-dimensional curved inner surface of a femoral alignment guide onto a corresponding three-dimensional femoral joint surface of the patient. The patient-specific three-dimensional curved inner surface is preoperatively configured from medical scans of the knee joint of the patient. First and second holes are drilled into an anterior portion of the femoral joint surface through corresponding first and second guiding apertures of the femoral alignment guide.

Patient-specific knee alignment guide and associated method

A method of preparing a surgical plan comprises video capturing a range of motion of an anatomic joint of a patient to obtain a range of motion video, registering the range of motion video to two-dimensional images of a skeleton of the patient, identifying potential impingement and stability issues in the anatomic joint based on the range of motion video, templating a prosthetic implant on two-dimensional images of the anatomic joint using the identified potential impingement and stability issues of the anatomic joint to obtain position and orientation data, and electronically saving the position and orientation data of the prosthetic implant for use with a surgical navigation system. A system for planning and performing a surgical procedure comprises a motion capture system, an x-ray system, an electronic modeling system, and a surgical navigation system.

An acetabular prosthesis is described that includes a shell having an outer surface and an inner surface, the outer surface defining an external shape. There is at least one through bore extending from the outer surface of the shell to the inner surface of the shell. At least one augment is configured to be positioned at least partially within the at least one through bore of the shell such that, in an assembled state, the shell and the at least one augment define a modified external shape.

A patient-specific acetabular guide can be used for preparing an acetabulum of a patient to receive an acetabular implant. The acetabular guide includes a patient-specific engagement surface designed to be complementary and mateable with a corresponding surface of the patient's pelvic anatomy. The acetabular guide is designed during a pre-operative plan for the patient by a three-dimensional reconstruction of the anatomy of the patient using two-dimensional medical images. The patient-specific engagement surface has a first portion mateable with a portion of the acetabulum of the patient. The acetabular guide includes a guiding element that extends from the acetabular guide opposite to the first portion of engagement surface. The guiding element defines a bore designed to be oriented along an alignment axis for an acetabular implant when the acetabular guide is engaged to the acetabulum.

Patient-specific acetabular guides and associated instruments

An orthopedic device for preparing a knee joint for a prosthesis in a patient includes a femoral alignment guide. The femoral alignment guide has a patient-specific three-dimensional curved inner surface preoperatively configured from medical image scans of the knee joint of the patient to nestingly conform and mate and match only in one position to a corresponding three-dimensional femoral surface of a joint surface of the patient. The femoral alignment guide has a first guiding aperture corresponding to a distal portion of the femoral surface and a second guiding aperture corresponding to an anterior portion of the femoral surface.

A method of preparing a joint for a prosthesis in a patient. The method includes obtaining scan data associated with the joint of the patient, preparing a three-dimensional image of the joint based on the scan data, preparing an interactive initial surgical plan based on the scan data, sending the surgical plan to a surgeon, receiving a finalized surgical plan from the surgeon, and preparing an image of a patient-specific alignment guide.

Patient specific knee alignment guide and associated method

A method of preparing a joint for a prosthesis in a patient. The method includes obtaining scan data associated with the joint of the patient, preparing a three-dimensional image of the joint based on the scan data, preparing a pre-operative surgical plan based on the scan data, and preparing an image of a patient-specific alignment guide, and intra-operatively modifying the surgical plan.

Patient specific alignment guide and inter-operative adjustment

An acetabular cup assembly implantable at an acetabular socket can include an acetabular cup defining a partially spherical bone engaging surface and having a uniform thickness. A spacer can include a body portion formed of porous metal and define a radial support surface. The porous metal can be adapted to receive bone ingrowth through interstitial space at pores defined therein. The spacer can further comprise a piercing portion adapted to be advanced into the acetabular socket. The spacer can bridge a gap defined between the acetabular socket and the acetabular cup. Filler can be disposed between the acetabular cup and the acetabular socket in areas adjacent to the spacer such that the spacer and the filler collectively define a continuous support surface adapted to support the acetabular cup at the bone engaging surface.
