Chapter 7144the native ACL should be reconstruction in all its shape and dimensions. A recent study has shown that anthropometric data can be used to predict the graft dimensions, by which means an appropriate graft can be selected preoperatively.24 That way true anatomic ACL reconstruction may become within reach.Finally, we would like to emphasize that the guides in the present study have been used in a situation that replicates open surgery. This allowed for visual feedback in addition to tactile feedback in search for the optimal fit. Therefore, the results of the current study cannot be translated oneon-one to an experiment in an arthroscopic setting. The next step is to develop a guide that can be used arthroscopically. This would ask for a slimmer design which special attention to allow for easy introduction through the portal. By further improving the design, the authors hope to further improve the accuracy of the patient specific guide. In this proof-of-concept study the use of 3D printed patient specific instrument for anatomic ACL reconstruction has been shown feasible. An accuracy of 5 mm is demonstrated on cadavers. Currently, this is not sufficient for the instrument to be used in a human population. Further improvement in the design and materials is needed before this concept can be introduced in an in vivo setting. Mark Zee.indd 144 03-01-2024 08:56
