摘要： A system for performing osteochondral transplantation surgery includes a harvesting guide tool for harvesting one or more osteochondral plugs and a transfer guide tool for insertion of each osteochondral plug in a damage site on an articular surface of a joint. A cartilage contact surface of each respective guide tool is adapted to follow the shape of a surface of cartilage or subchondral bone such that they conform to each other. Each respective guide tool includes one or more guide channels adapted to receive a respective surgical tool that slides within the guide channel, and is supported by the guide channel during surgery. The guide channels are configured to harvest and insert a plurality of osteochondral plugs of different sizes. The interiors of the guide channels are provided with markings for marking a rotational position of harvested plugs enabling positioning of the osteochondral plugs at a predetermined angle of rotation.

摘要： A method for designing and making a rig that includes a hollow tubular shell, and the interior of said shell defines at least first and second intersecting cylinders. The method includes identifying a damage area, presenting a 3D view of identified damage area, generating a 3D model of a virtual rig, and producing a rig according to the virtually created rig. The generating includes virtually placing in 3D view a shape covering or partly covering damage area, and creating, based on the position of the virtually placed shape, a position of hollow tubular rig shell of the virtual rig; and selecting the at least first and second intersecting cylinders of the virtual rig, based on the size and form of the virtually placed shape, and creating a positioning surface of the virtual rig which is a bone and/or cartilage-engaging end of hollow tubular shell.

摘要： A design method for designing a guide tool including a guide channel for use during cartilage repair in a joint is disclosed. The design method includes: selecting a direction along a joint axis indicating placement of the guide tool in the joint; and placing a positioning mark on the guide tool. The positioning mark is designed to be aligned with the center of said guide channel on a determined joint axis direction and thereby indicating a placement direction of the guide tool in relation to the selected joint axis during use of the guide tool. A design method of insert tools and/or an implant comprising positioning marks and also the guide tool, implant and insert tools designed using this method are also disclosed.

摘要： In accordance with one or more embodiments herein, a system for creating a decision support material indicating damage to at least a part of an anatomical joint of a patient, wherein the created decision support material comprises one or more damage images, is provided. The system comprises a storage media and at least one processor, wherein the at least one processor is configured to i) receive a series of radiology images of the at least part of the anatomical joint from the storage media; ii) obtain a three-dimensional image representation of the at least part of the anatomical joint which is based on at least a part of said series of radiology images, by generating said three-dimensional image representation in an image segmentation process based on said series of radiology images, or receiving said three-dimensional image representation from a storage media; iii) identify tissue parts of the anatomical joint in at least one of at least a part of said series of radiology images and/or the three-dimensional image representation using image analysis; iv) determine damage to the identified tissue parts in the anatomical joint by analyzing at least one of at least a part of said series of radiology images and/or the three-dimensional image representation of the at least part of the anatomical joint; v) determine suitable sizes and suitable implanting positions for one or more graft plugs based on the determined damage; vi) mark damage to the anatomical joint and suitable sizes and implanting positions for the one or more graft plugs in the obtained three-dimensional image representation of the anatomical joint; and vii) generate a decision support material, where the determined damage to the at least part of the anatomical joint and the suitable sizes and implanting positions for the one or more graft plugs are marked in at least one of the one or more damage images of the decision support material, and at least one of the one or more damage images is generated based on the obtained three-dimensional image representation of the at least part of the anatomical joint.

摘要： A system for determining and visualizing damage to an anatomical joint of a patient. The system is to: obtain a three dimensional image representation of an anatomical joint which is based on a medical image stack; determine damage to an anatomical structure in the anatomical joint by analyzing the medical image stack; mark damage to the anatomical structures in the obtained three dimensional image representation; obtain a 3D model based on the three dimensional image representation; and create a graphical user interface (GUI). The GUI may comprise: functionality to visualize and enable manipulation of the at least one 3D model; functionality to enable removal of the visualization of the anatomical structure from the 3D model; functionality to visualize and enable browsing of the medical image stack; and functionality to visualize the position of the medical image that is currently visualized.

摘要： A method for designing an implant includes designing a contour curvature of the implant so that an articulate surface of the implant is designed to correspond to a simulated healthy cartilage surface reconstructed from a 3D model based on one or more images taken with MRI or CT-scanning of a damaged cartilage surface of a joint; and providing a positioning mark on a surface of the implant. The positioning mark is provided such that the positioning mark is parted from the center of the implant to be visible for a surgeon and is adapted to be used for indicating a rotational position of the implant to the surgeon.
