Abstract

Purpose

The aim of this work is to evaluate the effectiveness of training with the low-fidelity ArthroBox® regarding performance of different basic arthroscopy tasks using a validated high-fidelity virtual reality simulator of the knee.

Methods

Nineteen volunteers (14 females and 5 males) without any previous experience in arthroscopy were randomly assigned either to the ArthroBox® training group (n =10) or the non-training group (n =9). The training group underwent a supervised ArthroBox ® training consisting of a daily 60-min session for three consecutive days. Both groups completed the basic and the final assessment using a validated virtual reality-based passive haptic knee arthroscopy simulator (ArthroS, VirtaMed™). The following three factors were measured in different exercises (explained in “Materials and methods”): amount of time to finish the task, length of camera and scope path within the joint. Furthermore, the volunteers’ demographics (age, sex, dexterity, video game experience, sport activities and profession) was assessed but showed no differences between the groups.

Results

There were no significant differences between the training and non-training group regarding the above-mentioned demographic factors. However, the training group showed significant improvement from baseline to follow-up in most activities (e.g. task performance time in seconds, intra-articular camera and grasp distance in centimetres; see Table 1) in comparison to the non-training group.

Conclusions

The results from this study demonstrate that training for three consecutive days using a portable and versatile low-fidelity simulator significantly improves arthroscopy performance when using a validated high-fidelity virtual knee simulator. Arthroscopic triangulation training outside the operating theatre with a portable, low-cost simulator has proven to be a valuable educational tool to improve the arthroscopic skills of trainee surgeons.
