A jig for revision surgery includes a body defining a contact surface(s) negatively corresponding to an articular surface of a primary implant. The body is configured to be coupled in a unique complementary coupling via engagement of the contact surface with the articular surface. A cut guide(s) is in the body, the cut guide(s) positioned relative to the at least one contact surface so as to be aligned with an underside of the primary implant or of a revision implant.

A surgical apparatus configured to be placed in the musculoskeletal system to precisely separate a first bone from a second bone. The surgical apparatus has one or more sensors to measure one or more parameters and supports one or more bone cuts for installing a prosthetic component. The surgical apparatus has three distraction mechanisms configured to increase or decrease a height between a first support structure and a second support structure. The tilt mechanism adjusts the tilt between the first support structure relative to the second support structure. The tilt mechanism of the surgical apparatus is adjusted from a first tilt to a second tilt to support a bone cut on one of the first or second bones.

Described here are self-contained surgical navigation systems which include a head-worn display device to be worn by a user during surgery. The system includes a display generator for generating a visual display on the display device, and a sensor suite having at least one tracking camera. The system further includes a support module including: a user-replaceable, modular battery that is removably insertable into a housing of the support module, and a processor unit configured to receive data from the sensor suite and calculate a position and an orientation of at least one marker. The support module is electrically coupled to the head-worn display device to provide power and data to the head-worn display device. The display device and the support module together comprise the entire sensing and computing capability of the system, without requiring external sensors, cameras, computers, or other electrical equipment.

A method for utilizing robotic surgical data for providing surgical training is disclosed. The method includes collecting, by a computing device, data related to a surgical procedure from one or more components of a computer-assisted surgical system. At least one of the one or more components is a robotically controlled surgical device. A graphical depiction representative of the surgical procedure is generated based on the collected data from the one or more components of the computer-assisted surgical system and one or more images providing a visual depiction of a patient's anatomy. A graphical user interface is output to a display device. The graphical user interface includes the graphical depiction of the surgical procedure and the collected data from the one or more components of the computer-assisted surgical system, to provide surgical training.

A method for utilizing robotic surgical data for a long term episode of care is disclosed. The method includes collecting data related to a surgical episode of care for a patient comprising pre-operative data, intraoperative data, and post-operative data. The intraoperative data is collected from one or more components of a computer-assisted surgical system. At least one of the one or more components is a robotically controlled surgical device. An analysis of the data related to the surgical episode of care is performed to evaluate one or more aspects of the surgical episode of care. A graphical depiction representative of the one or more aspects of the surgical episode of care is generated based on the performed analysis. A graphical user interface is output to a display device, the graphical user interface comprising the graphical depiction of the one or more aspects of the surgical episode of care.

A method for creating a patient-specific surgical plan includes receiving one or more pre-operative images of a patient having one or more infirmities affecting one or more anatomical joints, three-dimensional anatomical model of the one or more anatomical joints is created based on the one or more pre-operative images. One or more transfer functions and the three-dimensional anatomical model are used to identify a patient-specific implantation geometry that corrects the one or more infirmities. The transfer functions model performance of the one or more anatomical joints as a function of anatomical geometry and anatomical implantation features, surgical plan comprising the patient-specific implantation geometry may then be displayed.

A method of evaluating a human knee joint which includes a femur bone, a tibia bone, a patella bone, a patellar tendon, and ligaments, wherein the ligaments and patellar tendon are under anatomical tension to connect the femur and tibia together, creating a load-bearing articulating joint, the method including: inserting into the knee joint a gap balancer that includes a tibial interface surface, an opposed femoral interface surface, and at least one force sensor, the method including: providing an electronic receiving device; moving the knee joint through at least a portion of its range of motion; while moving the knee joint, using the electronic receiving device to collect data from the at least one force sensor; processing the collected data to produce a digital geometric model of at least a portion of the knee joint; and storing the digital geometric model for further use.

Systems for joint arthroplasty include prostheses which are secured to bone with sliding anchors. Examples include unicondylar and bicondylar knee prostheses for hemi-arthroplasty and total arthroplasty. Instruments guide the anchors into proper engagement with the prosthetic components. Methods of using the prostheses and instruments are disclosed.

An MTS medial tibial plateau patch, a modular MTS medial tibial plateau patch, and a minimally invasive replacement method thereof are disclosed. The MTS medial tibial plateau patch includes an articular surface provided with an arc-shaped recessed area and a bottom surface provided with 3 stand columns distributed triangularly, or two longitudinal keels having non-parallel distribution or two triangular keel wings, and the arc-shaped recessed area is well matched and in a sliding fit with a femoral condyle without an increase in impact in a joint, thus guaranteeing a stability of a prosthesis, realizing a concept of a minimally invasive surgery, and reducing damage to a normal tissue. The modular MTS medial tibial plateau patch includes a bone-trabecula metal tibial support and a liner made of VE high cross-linked polyethylene.

Methods, non-transitory computer readable media, and surgical computing devices are illustrated that improve robotic surgical systems. With this technology, one or more machine learning models are trained based on historical state data obtained for a computer-assisted surgical system (CASS) at each of a plurality of time periods during a plurality of historical knee arthroplasty surgical procedures. One or more of the machine learning models are applied to initial state data for a current knee arthroplasty surgical procedure to generate robotic commands required to achieve one or more future states of the CASS. The initial state data comprises a surgical plan. One or more surgical tools of the CASS are then manipulated based on the robotic commands to achieve the one or more future states of the CASS and thereby carry out at least a portion of the surgical plan.
