title: The effect of additional video documentation to photo documentation in wrist arthroscopies on intra- and interobserver reliability.
abstract: BACKGROUND
  The reproducibility of diagnoses based on photo documents in wrist arthroscopies is limited and is expected to improve through the addition of video documents.
  
  
  OBJECTIVE
  The purpose of this study was to determine the effect of additional video documentation to photo documentation on intra- and interobserver reliability in wrist arthroscopies.
  
  
  METHODS
  Sixty consecutive arthroscopies were documented by photographs of at least eight standard views and videos of the radiocarpal and midcarpal joints. After 3 months, the photographs and then the photographs together with the videos were reevaluated by the surgeon and by two hand surgeons to determine intra- and interobserver reliability. Percentage agreement and kappa coefficients were calculated.
  
  
  RESULTS
  Using videos along with the photographs did not improve reproducibility in general. The assessments of the cartilage status were even worse. Some of the videos were criticized as being too short to allow adequate assessment of the cartilage. Lesions of the TFCC as well as its tension were assessed notably better by the videos, whereas assessment of SL and LT ligaments was not improved by the videos. Intraobserver reliability was better than interobserver reliability.
  
  
  CONCLUSIONS
  As long as videos do not meet further quality criteria, they are not able to improve reliability in general. Nevertheless, videos should be used for documentation of the TFCC.
