Fig. 5From: 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 reconstructionSagittal, frontal and axial CT section of patella #10 postoperatively. Tunnel placement in a and b appears adequate. However, in c, two attempts made by the surgeon for proximal tunnel placement are revealed. The surgeon was probably unable to create a correct tunnel between previous attempted drillings. Blue arrow in b points at the postoperative bone bridge (red line) between transosseous sutures (BBS). Red arrow in b points at the postoperative bone bridge (orange line) between tunnels (BBT)Back to article page
