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. Preferably, the articulating surface 255 of the femoral trochlear implant 250 is a metal or ceramic surface; and the articulating surface 310 of the patellar implant 300 is not a metal or ceramic surface. The articulating surface 310 of the patellar implant 300 may be designed to correspond to the curvature of a simulated healthy articulating surface of the undamaged patella 600 at the site of diseased cartilage. The contour curvature of the articulating surface 310 may be generated based on the determined surface curvature of the cartilage and/or the subchondral bone in a predetermined area comprising and surrounding the site of diseased cartilage and/or bone in the patella 600, to mimic the original, undamaged, articulating surface of the patella 600.

A method may be provided to operate a medical system. First data may be provided for a first 3-dimensional (3D) image scan of an anatomical volume, with the first data identifying a blood vessel node in a first coordinate system for the first 3D image scan. Second data may be provided for a second 3D image scan of the anatomical volume, with the second data identifying the blood vessel node in a second coordinate system for the second 3D image scan. The first and second coordinate systems for the first and second 3D image scans of the anatomical volume may be co-registered using the blood vessel node identified in the first data and in the second data as a fiducial.

A bone graft generation and delivery process can include inserting bone material into an impactor system. The process can include processing, via the impactor system, the bone material into bone graft material. Processing the bone material can include milling the bone material via a first rotational element of the impactor system. Processing the bone material can include cutting the bone material via a second rotational element of the impactor system. Processing the material can include filtering the cut and milled bone material to isolate bone graft material. The process can include delivering, via the impactor system, the bone graft material to a target site.

A method of evaluating soft tissue of a human joint which includes two or more bones and ligaments, wherein the ligaments are under anatomical tension to connect the bones together, creating a load-bearing articulating joint, the method includes: inserting into the joint a tensioner-balancer that includes a means of controlling a distraction force; providing an electronic receiving device; moving the joint through at least a portion of its range of motion; while moving the joint, controlling the distraction force, and collecting displacement and distraction load data of the bones; processing the collected data to produce a digital geometric model of the joint, wherein the model includes: ligament displacement data along a range of flexion angles and ligament load data along a range of flexion angles; and storing the digital geometric model for further use.

The orthopedic system comprises a first plurality of shims of a first type, a second plurality of a second type, a measurement module, and the computer. The measurement module houses the electronic circuitry and at least one sensor. The measurement module is adapted to be used with the first plurality of shims and the second plurality of shims. The measurement module has a medial surface that differs from a lateral surface by shape, size, or contour.

Systems and methods for assisting users with accurate tool identification. A tool includes a tool feature, and a navigation system includes a localizer to detect a position of the tool feature. A memory stores identification data associated with a plurality of tools. Controller(s) is/are coupled to the navigation system, the memory and the display. The controller(s) receive, from the localizer, the detected position of the tool feature and compare the detected position of the tool feature with the identification data stored in the memory to determine an identity of the tool. The controller(s) present, on a display, the identity of the tool and an identity of at least one other tool.

A method of repairing a fractured bone may include implanting a prosthetic stem into an intramedullary canal of the fractured bone. First and second bone segments of the fractured bone may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the first end of the prosthetic stem. The first and second tuberosities may be machined so that the first and second bone segments have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the first end of the prosthetic stem, and the first interlocking surface interlocks with the second interlocking surface.

The invention relates to a surgical system for cutting an anatomical structure (F, T) of a patient according to at least one target plane defined in a coordinate system of the anatomical structure, comprising: i) a robotic device (100) comprising: —a cutting tool, —an actuation unit (4) comprising from three to five motorized degrees of freedom, said actuation unit comprising at least one portion having a parallel architecture comprising a base (40) and a platform (41) selectively orientable relative to the base (40) according to at least two of said motorized degrees of freedom, —a planar mechanism (24) connecting a terminal part of the actuation unit (4) to the cutting tool (2), ii) a passive articulated lockable holding arm (51) supporting the actuation unit, iii) a tracking unit (200) configured to determine in real time the pose of the cutting plane with respect to the coordinate system of the anatomical structure, iv) a control unit (300) configured to determine the pose of the cutting plane with respect to the target plane, to detect whether the cutting plane can be aligned with one target plane without changing the pose of the actuation unit, the control unit being further configured to, if the cutting plane cannot be aligned with the target plane, compute indication to a user to reposition the actuation unit with respect to the anatomical structure and, if the cutting plane can be aligned with the target plane, control the actuation unit (4) so as to bring the cutting plane into alignment with the target plane, v) a user interface coupled to the control unit, configured to indicate directions to a user to position the actuation unit with respect to the anatomical structure according to a pose allowing aligning the cutting plane with the target plane.
