摘要： 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.

摘要： A method of planning a patellar replacement for a patient is provided. Input related to patient anatomy is received (e.g., demographic information) and imaging data is obtained from 2D or 3D medical imaging Biomechanical measurements of the patellofemoral joint are determined including a mechanical axis and pre-operative leg deformity. A 3D model of the patient anatomy is generated based on the input, and the 3D model is characterized in terms of the morphology of the patella. An implant is sized and fitted to the 3D model and implant position and orientation are optimized based on the biomechanics. Results are outputted as a patient report or a surgical plan to a computing device and/or a storage medium. A tracker unit for tracking a patella bone is also provided. The tracker unit comprises a support configured to penetrate the patella and a fiducial marker for detection by a tracking system.

摘要： A joint tensioning device and methods of use thereof are disclosed. The joint tensioning device includes a flexing arm and a loading arm having a tensioning tip and a loading tip, respectively, configured for insertion into a joint. The flexing arm is coupled to the loading arm such that, during use, the loading arm may be adjusted to separate the tensioning tip and the loading tip to apply a distraction force to the joint. A strain gauge measures strain applied to the flexing arm based on the applied distraction force. The measured strain is used to determine the amount of force applied to the joint. The force data is employed in surgical planning to determine the amount of joint laxity when a particular load is applied to the joint.

摘要： Systems and methods for transmitting data in an operative setting are disclosed. A surgical system records data pertaining to a surgical procedure as the procedure is performed. The data is transferred to a portable electronic device, such as a cellular-enabled device, intermittently during the surgical procedure or after the surgical procedure is completed. The cellular-enabled device establishes a connection with a remote database that may be cloud-enabled for storage and analysis of the data.

摘要： Methods and systems for planning a joint replacement surgical procedure are disclosed. A musculoskeletal model for a patients joint and patient biometric data are received. A joint distraction device is positioned in the patients joint during the joint replacement surgical procedure, and the position and orientation of the joint distraction device are tracked as the patient's joint is moved through a range of motion in order to determine a magnitude of a force applied to the joint distraction device. A surgical plan for performing the joint replacement surgical procedure is provided based on the magnitude of the force applied throughout the range of motion, the musculoskeletal model, and the patient biometric data. The surgical plan includes implant position information, bone resection information, and/or ligament balancing information.

摘要： A surgical robotic arm (520) for use with an external vision system (512) includes onboard control and at least four degrees of articulation. The robotic arm (520) can position various tools (534) in the surgical theatre responsive to positional feedback from the vision system (512). Exemplary tools (534) include a handpiece (519) that includes a motorized burr or saw, a cutting guide (542) for a handheld saw, and a laser to actively define a resection area for a surgeon. The tool (534) or a reference point on the arm (520) relative to the tool (534) includes fiducial marks to register the position of the tool (534) with the vision system (512). Exemplary tools (534) are especially suited for knee and hip arthroplasty and can be moved under processor or manual control.

摘要： A method of determining patient-specific implant parameters for an implant used in a surgical procedure is described. A surgical system receives one or more initial transfer functions and one or more preoperative input factors for a patient and generates a surgical plan comprising one or more patient-specific implant parameters based on the one or more initial transfer functions and the one or more preoperative input factors for the patient. The surgical system further receives one or more intraoperative input factors for the patient and updates the one or more patient-specific implant parameters based on the one or more intraoperative input factors for the patient. An implant for the patient is selected based on the one or more updated patient-specific implant parameters.

摘要： Methods and system for characterizing ligament properties using elastography are disclosed. An ultrasound system capable of performing shear wave elasticity imaging and/or supersonic shear imaging may retrieve one or more images from a proposed surgical site. The one or more images may be provided to a surgical planning system that identifies one or more properties of ligaments proximate to the surgical site. Musculoskeletal simulations may be performed using the identified properties to preoperatively identify a surgical plan. Preoperative identification of a surgical plan may enable a surgeon to select from more fine-tuning options for a joint replacement than conventional systems.

摘要： A method for optimizing a knee arthroplasty surgical procedure includes receiving pre-operative data comprising (i) anatomical measurements of the patient, (ii) soft tissue measurements of the patient's anatomy, and (iii) implant parameters identifying an implant to be used in the knee arthroplasty surgical procedure. An equation set is selected from a plurality of pre-generated equation sets based on the pre-operative data. During the knee arthroplasty surgical procedure, patient-specific kinetic and kinematic response values are generated and displayed using an optimization process. The optimization process includes collecting intraoperative data from one or more surgical tools of a computer-assisted surgical system, and using the intraoperative data and the pre-operative data to solve the equation set, thereby yielding the patient-specific kinetic and kinematic response values. A visualization is then provided of the patient-specific kinetic and kinematic response values on the displays.
