Low-Cost Self-Made Arthroscopic Training Camera Is Equally as Effective as Commercial Camera: A Comparison Study

Abstract

To assess the effectiveness of a low-cost self-made arthroscopic camera (LAC) in basic arthroscopic skills training compared with a commercial arthroscopic camera (CAC). One hundred fifty-three orthopaedic residents were recruited and randomly assigned to either the LAC or CAC. They were allocated 2 practice sessions, with 20minutes each, to practice 4 given arthroscopic tasks: task 1, transferring objects; task 2, stacking objects; task 3, probing numbers; and task 4, stretching rubber bands. The time taken for participants to complete the given tasks was recorded in 3 separate tests; before practice, immediately after practice, and after a period of 3months. A comparison of the time taken between both groups to complete the given tasks in each test was measured as the primary outcome. Significant improvements in time completion were seen in the post-practice test for both groups in all given arthroscopic tasks, each with P < .001. However, there was no significant difference between the groups for task 1 (P= .743), task 2 (P= .940), task 3 (P= .932), task 4 (P= .929), and total (P= .944). The outcomes of the tests (before practice, after practice, and at 3months) according to repeated measures analysis of variance did not differ significantly between the groups in task 1 (P= .475), task 2 (P= .558), task 3 (P= .850), task 4 (P= .965), and total (P= .865). The LAC is equally as effective as the CAC in basic arthroscopic skills training with the advantage of being cost-effective. In view of the scarcity in commercial arthroscopic devices for trainees, this low-cost device, which trainees can personally own and use, may provide a less expensive and easily available way for trainees to improve their arthroscopic skills. This might also cultivate more interest in arthroscopic surgery among junior surgeons.
