A system for creating at least one model of a bone and implanted implant comprises a processing unit; and a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for: obtaining at least one image of at least part of a bone and of an implanted implant on the bone, the at least one image being patient specific, obtaining a virtual model of the implanted implant using an identity of the implanted implant, overlaying the virtual model of the implanted implant on the at least one image to determine a relative orientation of the implanted implant relative to the bone in the at least one image, and generating and outputting a current bone and implant model using the at least one image, the virtual model of the implanted implant and the overlaying.

Patient-specific instrumentation for implant revision surgery

A method of positioning posterior resection guides in a three-dimensional coordinate system using robotic arms to perform partial knee arthroplasties comprises connecting a first tracking device for a surgical tracking system of the robotic arm to a femur, connecting a second tracking device for the surgical tracking system of the robotic arm to a tibia, manually positioning the tibia relative to the femur to a desired orientation to perform a posterior resection, manually determining a position for the posterior resection guide to perform the posterior resection, digitizing a reference point for the posterior resection guide in the three-dimensional coordinate system for a location of a feature of the posterior resection guide, moving the posterior resection guide to the location in the three-dimensional coordinate system with the robotic arm, and resecting a posterior portion of a condyle of the femur using the posterior resection guide to guide a cutting instrument.

Devices and methods for posterior resection in robotically assisted partial knee arthroplasties

A system and method may be used to position or orient a camera within a surgical field. A method may include generating a graphical user interface including a first set of instructions to reposition the camera, and determining whether the camera is within a target volume location. The method may include automatically outputting an indication when the camera is within the target volume location. The method may include outputting a second set of instructions for display on the graphical user interface to align a laser, coupled to or integrated into the camera, to the tracker by changing an angle of the camera.

Optical camera positioning tool

A system for sizing an implant for a patient pre-operatively comprises a processor unit. A non-transitory computer-readable memory may be communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for obtaining at least one radiographic patient image of at least one patient bone with a scale marker relative to the bone, the scale marker having a known geometry, setting a scale of the at least one radiographic patient image using the known geometry of the scale marker, generating a three-dimensional bone model representative of the at least one patient bone using the at least one radiographic patient image and the scale, identifying an implant size and/or an implant model using implant models and dimensions of the three-dimensional bone model based on said scale, and outputting the implant size and/or the implant model for the patient.

Method and system for pre-operative implant sizing

Embodiments of a system and method for surgical tracking and control are generally described herein. A system may include a robotic arm configured to allow interactive movement and controlled autonomous movement of an end effector, a cut guide mounted to the end effector of the robotic arm, the cut guide configured to guide a surgical instrument within a plane, a tracking system to determine a position and an orientation of the cut guide, and a control system to permit or prevent interactive movement or autonomous movement of the end effector.

Robotic cutting workflow

Devices, systems and methods for controlling gap height for posterior resection in a partial knee arthroplasty can comprise A) use robotic surgery planning software to adjust an extension gap to suit a flexion gap to manually position a manual posterior cut guide; B) use a surgical navigation system to determine a femur rotation axis to properly manually position a manual posterior cut guide; C1) use shims to adjust the position of a manual posterior cut guide; C2) use a robotically-guided femur and tibia partial cut guide block to position a robot-configured posterior cut guide relative to the distal end of a femur; and D) use a robotically-guided femur and tibia partial cut guide block to guide pin holes for a robot-configured posterior cut guide relative to the distal end of a femur.

Patient-specific instrumentation for use when performing articular joint repair is provided. A patient-specific jig is adapted to be positioned over a bone at an articular surface thereof for assisting in preparing the bone surface for reception of a prosthesis. The jig comprises a bone contacting portion adapted to matingly contact a portion of the articular surface of the bone and a cutting slot adapted to receive therein a saw blade for resecting the articular surface of the bone. The cutting slot may be press-fitted into the opening of a cut guide. A patient-specific plate and a patient-specific rotational guide are also provided for guiding a positioning of the prosthesis over the resected surface of the bone. A method for manufacturing the patient-specific jig is further provided.

Patient-specific instrumentation and method for articular joint repair

Systems and methods may be used to perform robot-aided surgery. A system may include a display device and a computing device including a memory device with instructions. The instructions can cause the system to access surgical data, calculate medial and lateral gap data, calculate a recommended component set, and generate a graphical user interface. Accessing surgical data can include accessing soft tissue data indicative of at least tension in soft tissues surrounding a surgical location. The graphical user interface can include an interactive trapezoidal graphic overlaid onto a graphical representation of a distal femur and a proximal tibia. The interactive trapezoidal graphic can include a graphical representation of a medial total gap, a lateral total gap, and a recommended spacer size. The interactive trapezoidal graphic can update in response to adjustments in implant parameters to assist in surgical planning.

Soft tissue balancing in articular surgery

A pin placement instrument for placing a pin in a bone comprises an anatomical interface with a hook-like portion being opened in a lateral direction of the instrument to receive a bone therein in a planned position. A drill guide is connected to the anatomical interface and defining at least one guide slot in a longitudinal direction of the instrument. The guide slot has a lateral opening over its full length in the drill guide to allow lateral withdrawal of the instrument in said lateral direction with the pin placed in the bone passing through the lateral opening. A bushing is removably placed in said guide slot via said longitudinal direction in a planned fit, the bushing defining a throughbore aligned with the guide slot and adapted to receive the pin extending in said longitudinal direction when the bushing is in the guide slot for pin placement.
