Hands-On Lightly Embalmed Cadaver Lab for Teaching Knee Aspiration/Injection

Publication ID Published Version

This resource is a lab guide for student training and assessment of knee aspirations/injections using lightly embalmed cadavers as a “simulated patient”. Knee aspirations and injections are commonly performed clinical skills. However, due to time constraints, the variability of clinical rotations, and the types of patients seen, students may or may not be exposed to all of the clinical skills including knee aspirations/injections in which adequate training is needed. Lightly embalmed cadavers serve as an optimal “simulated patient” for a variety of reasons including: tissues are similar to living tissue in color, texture and elasticity; real anatomical landmarks are encountered and used to perform the clinical skill; and the use of the cadaver reduces anxiety about safety issues. To reduce the variability of, and potential inadequate training in knee aspirations/injections, this module was developed.

The module includes a lab guide describing lightly embalmed cadavers, descriptions for preparing a lightly embalmed cadaver knee joint for aspiration and injection, and a lab training session for students. A checklist and post-test for assessment of competency and knowledge complete the lab guide.

There are also two presentations, including videos of how to prepare a lightly embalmed cadaver for knee aspiration/injection and a tutorial addressing the indications, contraindications, complications, anatomy, equipment and the procedure for performing knee aspirations/injections.
