摘要： This disclosure relates to surgical instruments for alignment of bone cuts during surgeries on joints and in particular, during total replacement of joints. The surgical instrument comprises a contact surface shaped to fit a prepared end of the first bone of the joint and an artificial articular surface that imitates the native articular surface of the first bone that has been removed by the preparation of the first bone. The artificial articular surface is pivotable in relation to the surgical instrument. The instrument can be fitted onto the prepared bone and coronal balancing can be performed. After fixing a further instrument to the second bone the joint can be balanced in flexion. At the optimal flexion angle, the slope and the cutting depth can be adjusted to achieve alignment. The further instrument is then used as a guide for cutting the second bone at the resulting cutting depth, slope and varus/valgus angle.

摘要： This disclosure relates to systems and methods for managing patients of knee surgeries. A pre-operative patient questionnaire user interface is associated with a future knee operation of the patient. Patient input data is indicative of answers of a patient in relation to the pre-operative patient questionnaire. A processor of a computer system evaluates a statistical model to determine a predicted satisfaction value indicative of satisfaction of the patient with the future knee operation. The statistical model comprises nodes stored on data memory representing the patient input data and the predicted satisfaction value, and edges stored on data memory between the nodes representing conditional dependencies between the patient input data and the predicted satisfaction value. The processor then generates an electronic document comprising a surgeon report associated with the future knee operation to indicate to the surgeon the predicted satisfaction value.

摘要： The present disclosure relates to a method and system for configuring a surgical tool during surgery. A laser scanner generates sensor data and a processor determines spatial data indicative of a position of the anatomical feature and of a position of a tool interface that is fixed in relation to the anatomical feature based on the sensor data. The processor also determines a first desired spatial configuration of the surgical tool in relation to the tool interface based on the spatial data and a second desired spatial configuration of the surgical tool in relation to the anatomical feature. The outcome is more accurate and less complex than other methods, such as methods that are based on reference to the absolute positions of the anatomical feature and the surgical tool within an operation theatre.

摘要： A positioning guide system for guiding a surgical tool comprising a positioning guide and a user interface. The positioning guide comprising: an interface to correspond to a plurality of anatomic landmarks of a patient; a plurality of sensors to provide an output indicative of the proximity of the interface and one or more of the plurality of anatomic landmarks; and a tool guide, for a surgical tool, positioned relative to the interface. The user interface provides a user output indicative of correct positioning of the positioning guide and the anatomic landmarks of the patient based on the output of the plurality of sensors.

摘要： This disclosure relates to a computer assistant for a surgeon with a graphical representation of a dynamic knee score for a knee surgery. A processor receives computer tomography data of a current patient's knee and user input from the surgeon, the user input comprises an identifier of a knee implant. The processor then retrieves multiple machine learning model parameters indicative of a machine learning performed on historical patient records. For multiple values of a rotation of the tibial component and a slope of the tibial component the processor configures a post-operative kinematic model performs a kinematic simulation and estimates a current patient outcome by applying the machine learning model. Finally, the processor generates a shaded surface spanning the multiple values of a rotation of the tibial component and a slope of the tibial component on a user interface to graphically represent the estimated current patient outcome for each of the rotation and slope.
