Patient Perception of Allograft Versus Autograft in ACL Reconstruction Using a Validated Online Survey Marketplace.

Background: Little is known regarding the opinions of the general population on anterior cruciate ligament (ACL) graft options. Purpose: To evaluate the general population's perception of the use of allografts versus autografts in ACL reconstruction using a previously validated online marketplace platform. Methods: A prospective 34-question survey was distributed via the online marketplace. After collecting baseline demographics, participant preferences for ACL reconstruction with an allograft or autograft were established. All respondents completed a preeducation survey, reviewed an evidence-based education sheet, and completed a posteducation survey to assess their understanding. Upon completion, participants were asked which graft they would prefer. Participants were then asked if they would be willing to change their preference based on surgeon recommendation. Finally, participants were asked to rank the factors from the education sheet that were most influential. Study Design: Cross-sectional study. Results: There were 491 participants that completed the survey (mean age, 39.9 years [range, 19-72 years]; 244 male, 241 female, and 6 nonbinary/third-gender participants). Before reading the education sheet, 276 (56%) reported no graft preferences, 146 (30%) preferred autograft, and 69 (14%) preferred allograft. After reading the provided sheet, 226 (46%) participants preferred autograft, 185 (38%) preferred allograft, and 80 (16%) had no preference. The mean score on the preeducation test was 45%, and the mean score on the posteducation test was significantly greater (61%; P <.01). Overall, 345 participants (83.9%) stated they would change their preference for autograft or allograft if their surgeon recommended it. Surgeon preference (n = 330; 67%), educational information provided (n = 117; 24%), and previous knowledge (n = 44; 9%) were the most important factors for making graft selections. The mean ages of the participants selecting each graft type before and after education were as follows: allograft (37.8 ± 10.1 vs 40.6 ± 11.8 years; P =.05), autograft (38 ± 11.5 vs 39.5 ± 10.1 years; P =.21), and no preference (41.5 ± 11.2 vs 39.4 ± 11.8 years; P =.16). Conclusion: Education resulted in a greater number of individuals' reporting a preference in graft type (either allograft or autograft) compared with preinformation questioning. In addition, 83.9% of the participants were willing to switch their graft choice if recommended by their surgeon. [ABSTRACT FROM AUTHOR]
