    Abstract: An intramedullary alignment guide and method for use thereof are disclosed for accurately preparing and shaping the distal femur end surface to receive a knee prosthesis for securement thereto. The guide references the femur intramedullary canal to ensure that a distal femoral resector is properly positioned at a selected angle with respect to a patient's mechanical axis. In the preferred embodiment, the intramedullary alignment guide includes an opening for inserting an intramedullary rod therethrough and into the intramedullary canal of a patient. The present guide includes an adjustment mechanism which allows a surgeon to quickly and easily deflect an attached distal femoral resector into a desired angular displacement with respect to intramedullary canal. In accordance with the preferred method, the distal femoral resector angled with respect to the intramedullary canal so that a cut can be made in a patient's distal femur end which is perpendicular with the patient's mechanical axis. The present guide can be used on patients having various anatomies, and in operations involving both the right and left legs. A sighting tool is also disclosed which allows a surgeon to externally verify that the distal femoral resector is properly aligned with the patient's mechanical axis.

    Abstract: A system and method may be used to evaluate soft tissue. A knee arthroplasty soft tissue evaluation may use an adjustable spacer, such as varying sized physical spacers or an inflatable bladder, along with a sensor to measure force, pressure, gap distance, or the like during a range of motion test. A method may include maintaining an equal pressure or gap distance for a medial component and a lateral component of an adjustable spacer during a range of motion test. Information, including, for example a maximum or minimum gap distance or pressure may be determined during the range of motion test. The determined information may be output for display or used to update a surgical plan.

    Abstract: A device including a housing having a passage extending therethrough defining a drive shaft axis; a drive shaft supported within the passage and rotatable about the drive shaft axis; a drive housing defining a reaming axis and pivotably coupled to the housing to allow the reaming axis to deflect with respect to the drive shaft axis, a drive interface supported within the drive housing and rotatable about the reaming axis, the drive interface contacting the drive shaft such that rotation of the drive shaft about the drive shaft axis causes rotation of the drive interface about the reaming axis; and an angle adjustment control positioned remotely from a distal end of the housing and operably coupled to the drive housing to move the drive housing between a first position and a second position to define respective first and second offset angles between the reaming axis and the drive shaft axis.

    Abstract: A method includes receiving by a controller, a surgeon-specific surgery profile for an implantation of an implant into a joint, implant profiles, a patient-specific post-surgery desired functional profile of the joint after the implantation, and bone registration data for a first bone member and a second bone member of a patient are inputted into a surgical plan model to generate a surgical plan. The surgical plan model is designed to achieve the patient-specific post-surgery desired functional profile based at least in part on a plurality of dependencies between a plurality of surgical parameters, the implant profiles, at least one functional parameter representative of the expected functional performance of the joint, and movement-related data of the joint. The surgical plan is outputted on a graphical user interface (GUI) on a surgery assistant device to facilitate the implantation.

    Abstract: A system and method may be used to evaluate soft tissue. A hip joint evaluation may use an adjustable spacer, such as varying sized physical spacers or an inflatable bladder, along with a sensor to measure force, pressure, gap distance, or the like, for example during a range of motion test. A method may include using a maximum pressure during the range of motion test to determine a maximum pressure during the range of motion test. The maximum pressure may be output for display on a user interface.
