Fig. 3From: A computed tomography cadaveric study of the radiological anatomy of the patella: the size of the patella correlates with bone bridge between tunnels and R angles are introduced for safe tunnel drilling during MPFL reconstructionGraph, correlation between L1 and L1/2-L2. y axis is L1 and x axis is L1/2-L2. Perpendicular red dotted line represents the maximum bone bridge between tunnels equal to 1 cm and horizontal dotted line represents patella length equal to 3.25 cm. The blue line represents the correlation coefficient. Patellas shorter than 3.25 cm correspond to bone bridge shorter than the “desired” 1 cm lengthBack to article page
