Not Applicable

Completed

• Conditions: Simulation Training
• Interventions: Other: Anatomic Arthroscopy Simulation; Other: Pre-assesment education; Other: Non-Anatomic Arthroscopy Simulation

• Registration Number: NCT02752451
• Lead Sponsor: University of Arizona

Brief Summary

Comparison of success rates of novice surgeons to attain proficiency in basic arthroscopy skills after receiving prior training with different simulation systems.

Detailed Description

A non-anatomic set of training modules utilizing cigar boxes was developed at our institution to instruct residents in the basics of knee arthroscopy. Twenty-four medical students with no prior arthroscopic or laparoscopic experience were enrolled as subjects. Sixteen subjects were randomized to participate in four hours of either the cigar box arthroscopy trainer (CBAT) or a previously validated anatomic knee arthroscopy trainer (AKAT). The remaining eight subjects served as controls (CO). All subjects underwent a one-hour formalized training session provided by our orthopaedic sports faculty. Subjects' skills were assessed by one of two faculty members through repeated attempts at performing a diagnostic knee arthroscopy on a cadaveric specimen. Objective scores were given using the Basic Arthroscopic Knee Skill Scoring System. Total cost differences were also calculated.

Arm && Interventions

Group	Intervention	Description
AKAT	Anatomic Arthroscopy Simulation	8 Subjects who received 4 hours of simulation training on the Anatomic Knee Arthroscopy Trainer. They then underwent assessment on cadaveric specimens.
CO	Pre-assesment education	8 subjects who did not undergo arthroscopy simulation training prior to assessment on cadaveric specimens. These served as controls.
CBAT	Non-Anatomic Arthroscopy Simulation	8 Subjects who received 4 hours of simulation training on the Cigar Box Arthroscopy Trainer. They then underwent assessment on cadaveric specimens.
CBAT	Pre-assesment education	8 Subjects who received 4 hours of simulation training on the Cigar Box Arthroscopy Trainer. They then underwent assessment on cadaveric specimens.
AKAT	Pre-assesment education	8 Subjects who received 4 hours of simulation training on the Anatomic Knee Arthroscopy Trainer. They then underwent assessment on cadaveric specimens.

Primary Outcome Measures

Name	Time	Method
Success rate in reaching a level of minimum proficiency	1 hour	Subjects were told to perform serial knee arthroscopic examinations on a cadaveric specimen over one hour. Evaluators used a validated objective scoring system to assess performance and which subjects were able to attain a level of minimum proficiency.

Secondary Outcome Measures

Name	Time	Method
Number of attempts to reach minimum proficiency	1 Hour
