DEVICES, SYSTEMS, AND METHODS FOR DETERMINING TIBIA CORONAL ALIGNMENT

Systems and methods are disclosed for measuring a tibia varus or valgus angle 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; receiving, via the at least one processor, a first measurement of an anatomical feature of a leg of the patient; determining the tibia varus or valgus angle based on the first measurement; and causing a display to output the determined tibia varus or valgus angle. In some embodiments, instructions for implementing the method may be stored on a non- transitory computer readable medium.
