At this point, you have completed the first ArthroTrainer block. The first block includes exercises 1 to 6, and in it you work with the work and vision portals in parallel, which is the simplest way to work, as it is more easily orientable. In block 2, which includes exercises 7 to 11, you will replicate some of the previous exercises but with the vision and work portals perpendicular to each other. What that means is that, in this configuration, a right turn of the forceps translates into a left turn on the screen, which will force you to modify the way you view the arthroscopy.

This situation is similar to when we perform a shoulder arthroscopy with an anterior portal and a posterior portal, for example in a lateral decubitus position, among many other situations in which both portals are perpendicular.

The first block is the most complex since it includes learning how the device works. Now the setup is identical to the previous exercises and the objectives are similar, so this second and third block is lighter.

In this specific exercise, the objective is identical to exercise 1:

- Carry 3 rings from one basket to the other, but with the vision and work portals perpendicular

- You have 35 seconds to do it

- The main complexity of this exercise lies in having to adapt your way of understanding arthroscopy when the working portal and the vision portal are perpendicular.

- The number of repetitions you will need for this exercise is approximately 15.29 (SC 8.78 95% CI 10.77 – 19.81)

In this exercise you should not use the automatic camera, but rather the camera should be carried by hand
