Abstract: A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load, and joint alignment. The system further includes a remote system for receiving, processing, and displaying quantitative measurements from the sensors. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation. The kinetic assessment increases both performance and reliability of the installed joint by reducing error that is introduced by elements that load or modify the joint dynamics not taken into account by prior assessment methods.

Abstract: An alignment system for the muscular-skeletal system is disclosed. The system supports parameter measurement and alignment. The system comprises a sensored device, a reference position tool, and a remote system configured to receive and display sensor data. The sensored device includes a three-axis accelerometer configured to measure position, rotation, and slope. The reference position tool comprises a body, a first arm coupled to a proximal end of the body, and a second arms coupled to a proximal end of the body. The sensored device couples to the reference position tool. The first and second arms of the reference position tool couples to the muscular-skeletal system in predetermined locations to allow a position of the muscular-skeletal system to be referenced. The body of the reference position tool can extend and retract to adapt to different sized muscular-skeletal systems.

Abstract: A knee bone cut system and method is disclosed. The knee bone cut system supports cutting an anterior portion of a distal end of a femur. The system comprises a sensored insert, a femoral rotation guide, and a remote system to receive and display sensor data. The sensored insert provide data related to load magnitude, position of load, and leg position. The femoral rotation guide has moveable condyles to adjust condyle position in a rapid manner. A pinch mechanism and lock mechanism respectively move the condyles into contact with the sensored insert. Moreover, the femoral rotation guide can be loaded similar to a final installed insert over a range of motion. For example, the patella can be placed on the femoral rotation guide allowing the patella to load the sensored insert. The femoral insert guide includes guide holes that are used in conjunction with a bone cutting jig.

Abstract: A system and method for measuring medial-lateral tilt of a bone is disclosed. The bone is coupled to a joint of the muscular-skeletal system. The method comprises coupling a three-axis accelerometer to a prepared bone surface of a bone. The three-axis accelerometer is configured to measure position, rotation, and tilt. The joint is rotated between two points. The rotation between the two points traverses an arc having a maximum therebetween. The joint pivots off of a surface to which the bone is coupled. In one embodiment, a pivot point and joint rotation relates to a mechanical axis of the joint and bone. The three-axis accelerometer measures data points along the arc as it is rotated between the two points. Multiple passes along the arc generates sufficient data points to determine the maximum. The position of the maximum is used to calculate the medial-lateral tilt of the bone.

Abstract: A system and method for adjusting a contact point of a joint is disclosed. The system comprises a prosthetic component having sensors therein and a remote system to receive and display sensor data. A plurality of sensors of the prosthetic component provide data related to load magnitude and position of load applied to a surface of the prosthetic component. The prosthetic component further includes one or sensors that provide position, rotation, and tilt data. Adjustment of the contact point of the prosthetic component can be performed by repositioning the prosthetic component relative to a bone to which it is coupled. For example, a prosthetic component can be pinned to the bone allowing rotation of the prosthetic component relative to the bone in-situ. A remote system receives sensor data from the prosthetic component allowing viewing of the load magnitude, position of load, and rotation of the prosthetic component.

Abstract: A method is disclosed herein for aligning a bone cutting jig for a bone cut relative to a mechanical axis. The method utilizes a three-axis accelerometer in a device to measure position, rotation, and tilt. The device is coupled to a bone-cutting jig. The bone-cutting jig is coupled to a bone. A joint of the bone is placed in a predetermined flexion. The joint end of the bone is rotated between a first point and a second point. As the joint rotates it pivots off a pivot point related to the mechanical axis. The joint rotation is monitored on a remote system. The device transmits data related to an arc made by the joint as it is rotated. The alignment of the bone relative to the mechanical axis is calculated from the three-axis accelerometer data. The bone-cutting jig is positioned to cut the bone based on the alignment measurement.
