PURPOSE: To assess interobserver reliability between 2 surgeons, for real-time diagnostic arthroscopy and the corresponding videotape of shoulder pathology in patients with a clinical symptom complex consistent with shoulder impingement syndrome. TYPE OF STUDY: Prospective cohort. METHODS: Fifty-three patients with shoulder impingement syndrome underwent arthroscopic surgery by 1 of 2 experienced orthopaedic shoulder surgeons. All operations were videotaped. The surgeon who did not perform the surgery reviewed the videotaped procedure. The findings in the shoulder were independently documented by each surgeon on standardized shoulder information sheets. The video-review surgeon was blinded to the results of the arthroscopy and all preoperative workup information. The percentage agreement, kappa statistics, and correlations were calculated to assess the inter-rater reliability. RESULTS: The percentage agreement ranged from 100% for tendon ruptures to 39% when identifying acromion type. Interobserver kappa statistics were significant for all relevant structures with the exception of acromion type and coracoacromial ligament. CONCLUSIONS: There was satisfactory reliability between video and real-time arthroscopy. However, better objective definitions of pathology and standardization of arthroscopic techniques would improve these results. Videotaping of arthroscopy can be considered a useful educational tool, a way to improve communication between surgeons, and possibly a medicolegal tool when defining pathology in the shoulder. LEVEL OF EVIDENCE: Level II.
