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 on a curved surface, joint stability, range of motion, and impingement. In one embodiment, the system is for a cup and ball joint of a musculoskeletal system. The system further includes a computer having a display configured to graphical display quantitative measurement data to support rapid assimilation of the information. 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.

Abstract: Systems and methods are disclosed for measuring a femoral alignment of a femur of a patient via a surgically implanted measurement device. An exemplary method may include: receiving, via at least one processor, first data from the measurement device, wherein: a housing of the measurement device is coupled to a musculoskeletal system of a patient; and the first data includes a plurality of measurements from each of an accelerometer and a gyroscope included with an inertial measurement unit disposed within the housing; determining the femoral alignment based on the first data; and causing a display to output the determined femoral alignment.
