PURPOSE: This study was designed as a questionnaire survey to reveal the preference in technique of patients faced with anterior cruciate ligament (ACL) reconstruction. METHODS: One hundred and ten subjects (35 patients and 75 medical students) were included in this study. A questionnaire survey was conducted, and the following questions were asked: (1) How old are you? (2) Prior to this survey, did you know what the ACL was? (3) Prior to this survey, did you have any knowledge about ACL reconstruction technique? (4) Prior to this survey, did you know the difference between anatomical double bundle (DB) technique and traditional single bundle (SB) technique? (5) If you had to have an ACL reconstruction, which technique would you prefer? In the same questionnaire, between questions (3) and (4), a description of SB and DB was provided. RESULTS: Sixty-nine percent of patients and 100% of medical students knew what the ACL was. Forty-three percent of patients and 85% of medical students had previous knowledge about ACL reconstruction. None of the patients and only 29% of the medical students had prior knowledge about the difference between DB and SB. Six percent of patients selected SB, and 40% selected DB. Nine percent of medical students selected SB, and 67% selected DB. CONCLUSION: In this study, 46% of patients and 76% of medical students selected one of the operation techniques. The trend in selection of the operation technique was significantly influenced by the subjects' prior medical knowledge. It might be possible to apply the principle of "informed patient choice" to the selection of DB or SB for ACL reconstruction. LEVEL OF EVIDENCE: Decision analysis, Level III.
