Chapter 7140Figure 4. Example of comparison planned and drilled tunnels. Drilled tunnel is displayed in red. Planned tunnel in dark-gray. (a) Anterior Posterior view. (b) sagittal view. (c) Caudo-cranial view. (d) notch view. The intraclass correlation coefficient for intra-observer reliability regarding the distance measurements between the planned and achieved tunnel position was calculated to be excellent: 0.956 for average measures (95% confidence interval 0.558-0.997, p=0.01). DiscussionThe main finding of our study is that with our patient-specific targeting device a deviation of 5.0 mm exists compared to the planned tunnel. While the technique and development seem promising, this is outside our intended target of < 2mm. Mark Zee.indd 140 03-01-2024 08:56
