Introduction Arthroscopy is especially well suited to outpatient implementation, as procedures are less heavy for the patient. Few studies, however, have focused on patient information and understanding in arthroscopic and outpatient surgery. The aim of the present study was to perform a prospective assessment of the information received by the patient concerning outpatient arthroscopic surgery. The study hypothesis was that there is room for improvement in information. Materials and methods A prospective descriptive observational cohort study was made of the means of information available to patients, their understanding of arthroscopic surgery and their satisfaction with the information delivered. Inclusion criteria consisted in scheduled outpatient arthroscopic surgery in whatever joint. Results Fifty consecutive patients responded to the study questionnaire. Forty-eight (96%) considered that the surgeon had provided sufficient oral information. Twenty-nine (58%) considered that they had received sufficient written information. Forty-four (88%) reported searching on the Internet. Twelve (24%) had sought testimony and advice from someone who had undergone similar surgery. Eighteen (36%) had sought information from their community physician. Four (8%) had called back or taken a new appointment with the surgeon to get more information. Five (10%) attributed lack of information to lack of time in the preoperative consultation. Three (6%) considered the information to have been too technical for good understanding of the procedure. Discussion The present study showed that this cohort, which was relatively young compared to patients undergoing implantation, was notably autonomous in their search for information. They mainly sought information in general-public medical information websites, rather than from their community physician or specialist. Conclusion It is important to improve patient information, and specific tools should be implemented ahead of outpatient arthroscopic surgery. Level of evidence Four observational studies.
