Goal: Develop an effective high-fidelity model for the purpose of training orthopaedic surgeons. Objectives: This study had two objectives; I) the development of a flexible cadaver model for training orthopaedic surgery residents in basic arthroscopic skills and; II) the evaluation of the educational utility of the flexible cadaver model in comparison to the fresh-frozen cadaver model. Hypothesis: The flexible cadaver model is equivalent to the fresh-frozen cadaver model as a training resource for the development of arthroscopic skills. Materials and Methods: A human body was embalmed with a phenol-based embalming solution to create a flexible cadaver. A knee model was then developed and introduced to orthopaedic surgery residents and faculty at an arthroscopic skills training workshop. SurveyMonkey® was utilized to create and administer an online survey asking participants to rate a variety of statements regarding the educational utility of the flexible cadaver model and fresh-frozen cadaver models on Likert-type scales. Mean response values between the two models were calculated and compared. Results: The phenol-embalmed cadaver produced a high-fidelity knee model that workshop participants were unable to differentiate from the fresh-frozen cadaver model, except for some differences in colour. Survey responses supported our hypothesis that the flexible cadaver model is equivalent to the fresh-frozen cadaver model as a training resource for the development of basic arthroscopic skills. Conclusions: Two conclusions can be drawn from this study; I) the flexible cadaver model is at least equivalent in educational utility compared to the fresh-frozen cadaver model for the development of basic arthroscopic skills and; II) the flexible cadaver model is a promising resource for the development of arthroscopic skills.
