The development of skills in arthroscopic surgery is essential to the training of modern orthopedic surgeons. Few validated, objective tools exist which track improvement in arthroscopic skills. The purpose of this study was to validate an objective global assessment of arthroscopic skills employing videotape footage of diagnostic arthroscopy performed by participants of various skill levels on a cadaveric knee. A total of 22 participants with varying arthroscopic experience performed a recorded diagnostic knee arthroscopy on a cadaveric knee. Recorded footage of the procedures from an arthroscopic and external view was assessed by five blinded evaluators and scored on a global skills evaluation and checklist evaluation form. Interclass correlation coefficient analyses were used to determine the inter-rater reliability. Mean scores of novice and experienced residents and practicing arthroscopists (based on rank and experience) were compared using a students t-test.Purpose
