Regaining function is crucial for patients undergoing joint replacement. Dynamic function can be assessed objectively through tracking skeletal motion using markers attached to the skin. However, the precision of that approach has been limited in the often obese patients. The work here is the first demonstration that our rigorous mathematical framework allows tracking skeletal motion in patients with a precision that approaches theoretically optimal values determined from simulations. To enable the wider community to benefit from the technology we are currently integrating it into the commercial system of a UK-based global leader in gait analysis.
