Background: Examination of arthroscopic skill requires evaluation tools that are valid and reliable with clear criteria for passing. The Arthroscopic Surgery Skill Evaluation Tool was developed as a video-based assessment of technical skill with criteria for passing established by a panel of experts. The purpose of this study was to test the validity and reliability of the Arthroscopic Surgery Skill Evaluation Tool as a pass-fail examination of arthroscopic skill.
Methods: Twenty-eight residents and two sports medicine faculty members were recorded performing diagnostic knee arthroscopy on a left and right cadaveric specimen in our arthroscopic skills laboratory. Procedure videos were evaluated with use of the Arthroscopic Surgery Skill Evaluation Tool by two raters blind to subject identity. Subjects were considered to pass the Arthroscopic Surgery Skill Evaluation Tool when they attained scores of ≥ 3 on all eight assessment domains.
Results: The raters agreed on a pass-fail rating for fifty-five of sixty videos rated with an interclass correlation coefficient value of 0.83. Ten of thirty participants were assigned passing scores by both raters for both diagnostic arthroscopies performed in the laboratory. Receiver operating characteristic analysis demonstrated that logging more than eighty arthroscopic cases or performing more than thirty-five arthroscopic knee cases was predictive of attaining a passing Arthroscopic Surgery Skill Evaluation Tool score on both procedures performed in the laboratory.
Conclusions: The Arthroscopic Surgery Skill Evaluation Tool is valid and reliable as a pass-fail examination of diagnostic arthroscopy of the knee in the simulation laboratory.
Clinical relevance: This study demonstrates that the Arthroscopic Surgery Skill Evaluation Tool may be a useful tool for pass-fail examination of diagnostic arthroscopy of the knee in the simulation laboratory. Further study is necessary to determine whether the Arthroscopic Surgery Skill Evaluation Tool can be used for the assessment of multiple arthroscopic procedures and whether it can be used to evaluate arthroscopic procedures performed in the operating room.
