Abstract: A patellofemoral implant arrangement for repairing damage in a patellofemoral articulation of a patient is provided. The patellofemoral implant arrangement includes a femoral trochlear implant, including an articulating surface, and a patellar implant, configured to be inserted, for example with press-fit, into a recess in a patella in such a way that the perimeter of an articulating surface of the patellar implant does not extend beyond a surrounding articulating surface of the patella. The articulating surfaces of the femoral trochlear implant and the patellar implant are designed to allow that they at least partly interact with each other when the implants are implanted into the knee joint and the patella lies in the intercondylar groove of the femur. The articulating surface of the patellar implant may be designed to correspond to the curvature of a simulated healthy articulating surface of the undamaged patella at the site of diseased cartilage.

Abstract: In accordance with one or more embodiments herein, a system for turning a patient's dysplastic or deformed patellofemoral joint into a healthier patellofemoral joint is provided. The system comprises at least one processor arranged to: analyze the curvature of the patella in a patellofemoral joint; analyze the curvature of the femoral trochlea in said patellofemoral joint; and determine whether any of said analyzed curvatures indicate that the patellofemoral joint is dysplastic or deformed. If any of said analyzed curvatures indicate that the patellofemoral joint is dysplastic or deformed, the at least one processor is arranged to propose an improved curvature of the articulating surface of the patella and/or the femoral trochlea; and determine the shape and dimensions for a patellar implant that would create said improved curvature of the articulating surface of the patella, and/or a trochlear implant that would create said improved curvature of the articulating surface of the femoral trochlea.

Abstract: 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.

Abstract: In accordance with one or more embodiments herein, a patellofemoral implant arrangement 200 for repairing damage in a patellofemoral articulation of a patient is provided. The patellofemoral implant arrangement 200 comprises a femoral trochlear implant 250, comprising an articulating surface 255, and a patellar implant 300, configured to be inserted, preferably with press-fit, into a recess 620 in a patella 600 in such a way that the perimeter of an articulating surface 310 of the patellar implant 300 does not extend beyond a surrounding articulating surface of the patella 600. The articulating surfaces 255, 310 of the femoral trochlear implant 250 and the patellar implant 300 are designed to allow that they at least partly interact with each other when the implants 250, 300 are implanted into the knee joint and the patella 600 lies in the intercondylar groove of the femur.
