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 methods and systems to assist in surgery of a joint. The system determines a mechanical property of one or more ligaments associated with the joint based on measurement data indicative of a movement of the bones relative to each other under multiple mechanical loads. The system then determines a predicted characteristic of the joint after the surgery based on a spatial parameter of the surgery and based on the mechanical property of the one or more ligaments and generates an output signal indicative of the predicted characteristic to assist the surgery. Since the predicted characteristic of the joint is determined based on the mechanical property of the ligaments, the prediction is more accurate than other methods that rely on only bone geometries to predict a surgery outcome.

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.
