Abstract: An apparatus, system, and method for compensating for bone loss of a patient's knee joint during the performance of an orthopaedic surgical procedure includes determining an estimated amount of bone loss of a bone of a patient's knee joint, determining an anatomical distance between a femoral anatomical feature of a patient's femur and a tibial anatomical feature of a patient's tibia, and adjusting the determined anatomical distance based on the estimated amount of bone loss. The determined anatomical distance is indicative of a ligament length of a collateral ligament of the patient's knee joint. The bone loss may be estimated based on, for example, a surface curve fitting algorithm applied to a three-dimensional model of the bone, a defined bone loss amount provided by a user, or a comparison of the three-dimensional model of the bone to a statistical shape model that approximates the bone in a healthy state.

Abstract: A superconducting anti-fuse based field programmable gate array (FPGA) may include a first set of superconducting passive transmission lines, a second set of superconducting passive transmission lines, and at least one anti-fuse located at an intersection of a first superconducting passive transmission line from the first set of superconducting passive transmission lines and a second superconducting passive transmission line from the second set of superconducting passive transmission lines. A first terminal of the anti-fuse may be electrically connected to the first superconducting passive transmission line and a second terminal of the anti-fuse may be electrically connected to the second superconducting passive transmission line. The anti-fuse may transition from a first state having a non-zero resistance to a second state having a zero resistance below a critical temperature.

Abstract: A method for designing a uni-compartmental orthopaedic prosthesis includes generating a three-dimensional statistical model of a knee joint, determining a curvature of a section of a bone of the knee joint represented by the three-dimensional statistical model, and designing a section of the uni-compartmental orthopaedic prosthesis corresponding to the section of the bone of the knee joint to have a curvature that matches the curvature of the section of the bone of the knee joint. Additionally, a tibial and femoral uni-compartmental orthopaedic prosthesis are also disclosed, each of which includes a section having a curvature that matches a corresponding section of a corresponding bone of the knee joint represented by the three-dimensional statistical model.

Abstract: A unicondylar posterior cutting block, method of use and kit of surgical components are provided, with the cutting block comprising: a base which is mountable on a resected proximal tibial surface of a knee of a patient in use; and a body pivotally attached to the base, the body including an alignment formation arranged to align with a marking on a femur in use, the body defining a cutting guide therein for receiving a cutting instrument to make a unicondylar posterior cut in the femur and wherein moving the alignment formation to align with the marking on the femur causes the body to rotate relative to the base and to tilt the cutting guide relative to the base. Different bases offer different cut positions and rotation of the base offers further different cut positions.
