A surgical navigation system comprises a computer system, a tracking system and a projector. The computer system includes instructions for performing a surgical plan. The tracking system is electronically connected to the computer system and has a viewing area in which markers can be located within a three-dimensional space relative to the viewing area. The projector is electronically connected to the computer system and has a beam projectable into the viewing area to display a step of the surgical plan based on a location of a marker. A method for guiding a surgical instrument comprises tracking a surgical instrument within a three-dimensional space using a computer-operated tracking system, matching the surgical instrument to a step in a surgical plan for conducting the surgical procedure using the surgical instrument, and projecting a visual instruction into the three-dimensional space for the step in the surgical plan related to the instrument.

Surgical system having assisted navigation

Systems and methods may use an augmented reality device during a surgical procedure. The systems and methods may use an augmented reality display of an augmented reality device to present or project a virtual feature during a surgical procedure while permitting physical aspects of a surgical field to be viewed through the augmented reality display. The virtual feature may include aspects of a preoperative plan, a surgical device, an anatomical aspect of a patient, etc.

Augmented reality supported knee surgery

Example implants, systems and methods using sensors for orthopedic surgical assessment and/or planning are described herein. An example system can include a wearable sensor device for pre-operative use by a patient before an orthopedic surgery to generate pre-operative sensor data. The system can also include an implantable sensor device (e.g., a bone implant) to generate and aggregate post-operative sensor data associated with the patient after the surgery. The system can retrieve the pre-operative sensor data and the post-operative sensor data and predict, analyze or assess an outcome of the surgery.

Implants, systems and methods for surgical planning and assessment

Surgical system having assisted optical navigation with dual projection system

An apparatus for preparing a bone for receiving a prosthesis comprises a template that can secure to the bone, a revision alignment member for coupling to the template, an offset alignment bushing receivable by the template such that an intramedullary member seated in the first bone can extend through a passage defined by the offset alignment bushing, a first bone cutting bushing receivable by the template after removal of the offset alignment bushing and positioned to cut the bone, a second bone cutting bushing receivable by the template after removal of the offset alignment bushing and removal of the bone cutting bushing, said second bone cutting bushing having a rotational orientation corresponding to a rotational orientation of the offset alignment bushing such that the second bone cutting bushing is a guide for cutting the bone in preparation of the bone to receive the prosthesis with an offset adapter.

Knee joint prosthesis system and method for implantation

A unicondylar resurfacing femoral component including a metallic base member and a polymeric articulation member. The metallic base member includes a main body and a retention member extending from the main body configured to be secured within a condyle of a femur. The polymeric articulation member is coupled to the main body of the metallic base member and includes an articulation surface configured to articulate directly against a planar surface of a metallic tibial component.

Convertible pre-partial knee replacement

A knee prosthesis system constructed in accordance to one example of the present disclosure can include a femoral component, a tibial component, a first femoral component insert, a second femoral component insert, a first tibial bearing, and a second tibial bearing. The knee prosthesis system may be configured in one of a non-hinged configuration and a second hinged configuration. In the first non-hinged configuration, the first femoral component insert is positioned relative to the femoral component and the first tibial bearing is positioned onto the tibial component. In the second hinged configuration, the second femoral component insert is positioned relative to the femoral component and the second tibial bearing is positioned onto the tibial component.

Knee prosthesis systems and methods

A method of preparing a distal femur for a knee joint implant includes mounting a patient-specific bone engagement surface of a femoral alignment guide on a complementary surface of a distal femur of a patient. A plurality of alignment pins is inserted through a corresponding plurality of guiding bores of the femoral alignment guide into the distal femur. A cutting guide is mounted on first and second alignment pins of the plurality of alignment pins, and a first resection of the distal femur is made using the cutting guide while cutting through the femoral alignment guide.

Patient-specific orthopedic instruments

A method of implanting a prosthesis based on bone density of a bone is provided. A first bone density of the bone may be determined at a first portion of the bone. A second bone density of the bone may be determined at a second portion of the bone. A first desired amount of bone removal may be determined at the first portion of the bone based on the first bone density. A second desired amount of bone removal may be determined at the second portion of the bone based on the second bone density. The desired amounts of bone may be removed from the first and second portions of the bone. A prosthesis may be selected and implanted.

Method of implanting a knee prosthesis based on bone density

A method for preparing a first bone for receiving a prosthesis. The method includes coupling a revision alignment member to a template; positioning an offset alignment bushing relative to the revision alignment member; positioning the offset alignment bushing at the first bone such that an intramedullary member seated in the first bone extends through a passage defined by the offset alignment bushing; replacing the offset alignment bushing with a first bone cutting bushing; cutting the first bone using the first bone cutting bushing as a guide; replacing the first bone cutting bushing with an offset second bone cutting bushing; providing the second bone cutting bushing with a rotational orientation corresponding to a rotational orientation of the offset alignment bushing; and cutting the first bone using the offset second bone cutting bushing as a guide to prepare the bone to receive an offset prosthesis adapter.
