  • Publication number: 20240245412
    Abstract: Methods and systems for identifying and determining the size and orientation of a reamed portion of a patient's bone are disclosed. A tracking array and/or point probe may be inserted into an adapter device. The adapter device comprising a plurality of openings, having various connection means therein, such that when the tracking array is inserted into the adapter, a secure and robust connection is created. A reamer, stem, or similar tool may then be inserted into the opposing side of the adapter, during which, a secure and robust connection is created between the adapter and the tool. Thus, through the use of Computer Assisted Surgery Systems, a more accurate representation of the patient's anatomy can be obtained.

  • Patent number: 11642138
    Abstract: Disclosed herein is a patella clamp configured to grip a patient's patella. The patella clamp includes a clamping assembly, a ratchet arm assembly, and a handle assembly. The clamping assembly includes first and second patella grip portions mounted in opposing relationship. In use, actuation of the handle assembly moves the second patella grip portion towards the first patella grip portion to clamp the patient's patella. The handle assembly is configured to be moveably adjustable (e.g., rotatable) relative to the clamping assembly. For example, each of the first and second patella grip portions are coupled to mating features mounted on the ratchet arm assembly. Decoupling of the mating features allows the first and second patella grip portions to rotate about the longitudinal axis of the ratchet arm assembly. Thus arranged, the patella clamp is configured to enable the surgeon to reposition the handle assembly to provide increased visibility, etc.

  • Patent number: 11602361
    Abstract: Patient specific implant technology, in which an outline representation of a portion of an outer surface of a periphery of a bone volume is determined and the outline representation is used in operations related to implant matching. In addition, an instrument may be made to match a perimeter shape of a Patient Specific Knee Implant with features for locating holes in a distal femur such that posts or lugs in a femoral implant locate the femoral implant centered medial-laterally within an acceptable degree of precision to prevent overhang of either the side of the femoral implant over the perimeter of the distal femur bone resections. Further, a two-dimensional outline representation may be segmented into segments that correspond to resection cuts used in fitting an implant on a portion of a bone and operations related to implant matching may be performed based on the segments.

  • Publication number: 20220133485
    Abstract: A hinged knee prosthesis comprises a tibial component and a femoral component. The tibial component is configured to attach to a tibia. The tibial component has a bearing surface. The femoral component is configured to hingedly attach to the tibial component and rotate relative to the tibial component. The femoral component comprises a medial condyle and a lateral condyle. The medial and lateral condyles have an eccentric sagittal curvature surface configured to rotate and translate on the bearing surface of the tibial component.

  • Publication number: 20210315640
    Abstract: A computer-implemented method of improving a patello-femoral response is described. A computing system characterizes an anterior geometry of a patella and determines a position of a posterior apex of the patella in relation to one or more features of the anterior geometry of the patella. The computing system further receives location information related to the patella as a knee joint is moved through a range of motion. The computing system provides one or more recommendations to improve a patello-femoral response.
