Hands-On Lightly Embalmed Cadaver Lab for Teaching Knee Aspiration/Injection
|9187||July 2, 2012||1|
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.

Effectiveness and Significance
This lab has been taught to the University of Nebraska Medical Center senior physician assistant students since 2009, and it has also been offered as part of a continuing medical education course at the Nebraska Association of Physician Assistant 36th annual spring meeting. Both students and licensed physician assistants have reported positive feedback from the experience. Preliminary data collected from the physician assistant students indicates improved technique and better retention for performing knee aspirations and injections.
Special Implementation Guidelines or Requirements
- Must have access to lightly embalmed or fresh frozen cadavers and a lab space equipped to accommodate cadavers.
- PowerPoint presentations work best with PowerPoint 2010. All other implementation guidelines are included in the Instructor’s Manuel.
- Exposing preclinical students to lightly embalmed cadavers motivates learning and enhances retention and confidence. The use of the lightly embalmed cadaver also reduced the student’s anxiety about safety issues associated with performing knee aspirations/injections.
- Practicing health care professionals benefited from a review of important anatomy of the region and the proper technique for performing knee aspirations/injections.
- Lightly embalmed cadavers very realistically simulated a live patient.
