The Patellofemoral Entry Point–Transition Point Angle: Digitalization and Reliability Analysis
The EP-TP angle is significantly different between PFI patients and controls. This study presents a digital approach for measuring the EP-TP angle, in contrast with the initially described method, which required 3D prints. This digital approach, when aided with curvature mapping, yields better reliability.
