  • Patent number: 11020246
    Abstract: A force and rotation sensing device can be suitable for measuring a force within a knee joint. A force sensor can measure a force exerted between opposing surfaces of a housing. A force display positioned on the housing can visually represent a value of the measured force, such as with a dual-sided light-emitting diode display that is visible from opposing sides of the housing. A first rotation sensor can measure a flexion/extension position of the housing. A flexion/extension display can visually represent a value of the measured flexion/extension position. In some examples, a zero button can set a reference orientation of the housing, so that the first rotation sensor can measure the flexion/extension position as a relative rotation with respect to the reference orientation. In some examples, circuitry can wirelessly transmit data corresponding to the value of the measured flexion/extension position.

  • Patent number: 10966788
    Abstract: The subject matter includes a system and method for providing graphical feedback visualizing forces within a joint through a range of motion of the joint. The method can comprise receiving position data, receiving force data, and generating a graphical representation based on the position data and the force data. The receiving position data can include data for at least one bone of a joint while the at least one bone is moved through a range of motion (ROM). The receiving force data can occur concurrently to receiving the position data and using one or more processors, the force data can be collected from at least one force sensor embedded within a trial prosthesis in the joint. The graphical representation can illustrate changes in the force data versus locations of the bone as it moved through the ROM.

    Abstract: Methods and instruments for performing a kinematically-aligned total knee arthroplasty (TKA) are disclosed. Goals of the kinematically-aligned TKA can include restoration of (1) the femoral and tibial joint lines to the patient's natural joint line, (2) the patient's Hip-Knee-Ankle alignment to their constitutional alignment prior to developing osteoarthritis and (3) restoration of the patient's natural soft tissue laxity and envelope. A shim block assembly can be used in resecting the distal medial and lateral condyles to account for cartilage wear on the distal condyles from osteoarthritis. The shim block assembly can include a plurality of shims, and each shim can be attachable to or integral with a reference block. At least one of the plurality of shims can have a medial portion with a thickness different from a thickness of a lateral portion of the shim. The shims need not be joined together as a single medial/lateral component but may be independent of one another.
