From: 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 reconstruction

Fig. 4

Sagittal, frontal and axial CT section of patella #7 postoperatively. Tunnel placement in a and b appears adequate. However, in c, multiple attempts (with breaching of the articular surface and the anterior cortex) made by the surgeon for proximal tunnel placement are revealed. 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)
