A TPLO plate configured to accommodate flexible strands (flexible loops) attached to tissue to be attached to bone. The TPLO plate has one or more suture eyelets, to allow the user (surgeon) to pass a flexible strand through the eyelets and attach/reattach the tissue to the plate at the anatomical location, and to improve the rotational stability of the joint or bone. The eyelets may have various shapes, forms and configurations and may be provided on or within a surface of the TPLO bone plate in any number, depending on the characteristics of the fractured bone or bone segments, or of the plate design. The eyelets preferably receive one or more flexible strands.

An implant resection system for preparing an implant site to replace a defect in an articular surface of a first bone includes a first guide configured to be coupled generally to the first bone. The first guide includes a body portion defining a channel configured to receive a pin, wherein the pin is configured to penetrate and form a longitudinally disposed bore within the first bone. The implant resection system further includes a second guide configured to be coupled generally perpendicular to the first bone proximate to the defect by way of the bore. The second guide includes a drill bit configured to form an excision site through a portion of the articular surface in preparation of receipt of an implant.

An optical shape sensing system includes an attachment mechanism (130) being configured to secure an optical shape sensing fiber to an instrument, the optical shape sensing fiber being connected to the instrument and configured to identify a position and orientation of the instrument. An optical shape sensing module (115) is configured to receive feedback from the optical shape sensing fiber and register the position of the instrument relative to an operating environment. A position response module (144) is configured to provide feedback to an operator based on position or orientation of the instrument to guide usage of the instrument.

A surgical system includes a base, a robotic arm extending from the base and comprising a plurality of segments, a first tracker secured to the base, a second tracker secured to a segment of the plurality of segments of the robotic arm, and a detection device configured to determine an arrangement of the first tracker and the second tracker.

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: —an end effector (2), —an actuation unit (4) having at least three motorized degrees of freedom, configured for adjusting a position and orientation of the end effector (2) relative to each target plane, —a passive planar mechanism (24) connecting the terminal part (40) of the actuation unit (4) to the end effector (2); (ii) a tracker (203) rigidly attached to the end effector (2), (iii) a tracking unit (200) configured to determine in real time the pose of the end effector (2) with respect to the coordinate system of the anatomical structure, a control unit (300) configured to determine the pose of the end effector with respect to the target plane and to control the actuation unit so as to bring the cutting plane into alignment with the target plane.

A modular system for total knee arthroplasty includes a modular trial implant assembly. The modular implant assembly includes an elongate shaft configured for insertion into an elongate cavity in a bone, a reamer removably coupleable to the elongate shaft via a connection that allows the reamer to rotate while the elongate shaft remains in a substantially fixed angular orientation. The reamer has an outer surface that tapers toward the distal end configured to form a tapered cavity in an end of a bone in which the reamer is inserted and rotated. The modular trial implant assembly further includes a trial implant removably coupleable to a proximal end of the reamer. A modular final implant assembly includes an elongate stem, a tapered body and an implant body, each having a size and shape that can substantially correspond to a size and shape of the elongate shaft, the reamer and the trial implant, respectively.

A navigation system includes a first and second tracker supports independently affixed to a rigid object and separated by a distance. A first plurality of trackable elements are secured to the first tracker support and a second plurality of trackable elements are secured to the second tracker support. A localizer tracks the trackable elements and controller(s) define a tracking arrangement to be tracked based on a combination of the first and second plurality of trackable elements. A geometry of the tracking arrangement is registered relative to the rigid object and the controller(s) track the rigid object by detecting the registered geometry. The controller(s) identify a condition wherein at least one trackable element has been displaced relative to the registered geometry, and in response, generate an instruction to a manipulator controller to interrupt operation of a robotic manipulator.

Methods and devices are disclosed relating improved articular models, implant components, and related guide tools and procedures. In addition, methods and devices are disclosed relating articular models, implant components, and/or related guide tools and procedures that include one or more features derived from patient-data, for example, images of the patient's joint. The data can be used to create a model for analyzing a patient's joint and to devise and evaluate a course of corrective action. The data also can be used to create patient-adapted implant components and related tools and procedures.

Systems and methods for joint replacement are provided. The systems and methods include a surgical orientation device, a reference sensor device, and at least one orthopedic fixture. The surgical orientation device, reference sensor device, and orthopedic fixtures can be used to locate the orientation of an axis in the body, to adjust an orientation of a cutting plane or planes along a bony surface, or otherwise to assist in an orthopedic procedure(s).

A system and associated instruments for locating, and accurately and controllably delivering, a device to an area sufficiently near a bone defect using anatomical landmarks is provided. The instruments allow the surgeon to navigate to the area around the bone defect quickly and easily, while so facilitating proper insertion of the device. In some embodiments, the defect is located on a femur. Guide instruments having a plurality of device portals are also provided for use as standalone instruments or as accessories to the system. In addition, a protective guide sleeve is provided for the insert of small diameter devices.
