  • Publication number: 20170347962
    Abstract: A method includes obtaining load-deformation data for a joint, the load-deformation data being gathered via joint testing implemented by robotic test equipment, the robotic test equipment being configured for movement of the joint and comprising sensors to gather the load-deformation data during the movement. A load-deformation curve function for the load-deformation data is generated, the load-deformation curve function defining a curve fitted to the load-deformation data. A feature of the curve defined by the load-deformation curve function is quantified. A biomechanical characteristic of the joint is identified based on the quantified feature of the curve defined by the load-deformation curve function.

  • Publication number: 20170347945
    Abstract: A knee examination method includes the steps of situating a patient on a patient support adjacent a robotic knee testing apparatus, setting up the robotic knee testing apparatus, further setting up the leg of the patient relative to the robotic knee testing apparatus, and, after the steps of setting up and further setting up, examining knee laxity of a knee of the patient. The step of examining includes operating the robotic knee testing apparatus to manipulate the tibia positioning assembly.

  • Publication number: 20170143250
    Abstract: A joint manipulation and evaluation apparatus has a mechanism configured to manipulate a first bone of a joint relative to a second bone of the joint. The apparatus has a joint stabilizer arranged to engage the joint and hold the second bone in place as the first bone is manipulated. A sensor is coupled to the joint stabilizer and is configured and arranged to detect residual movement of a clamped portion of the joint relative to the joint stabilizer as the first bone is manipulated.
