This PowerPoint presentation was created in order to educate members of the healthcare team, including residents, nurses, etc. on the total knee replacement procedure. Having a background of the procedure can enhance the post-operative care given to the patient by the nursing staff. The overview of the procedure also serves as a suitable refresher for the resident, physician assistant, or operating room nurse that will be aiding in the procedure. The audience consisting of fellow healthcare professionals allows the PowerPoint to use medical terminology and abbreviations without explanation, keeping the text concise and to the point. The presentation could be accessed through a learning portal, requiring these individuals to review the PowerPoint, or through an in-service presented to the audience. The design was chosen to reflect the hospital atmosphere of whites and light blues, while preventing the background from becoming distracting. Pictures were placed generously throughout the presentation in order to compliment the text and appeal to both visual and verbal learning styles. In order to enhance the ability of the audience to effectively follow the information, the content is structured chronologically. Brevity was used in the content of the presentation, omitting all unnecessary information to keep the attention of the medicinal professional audience addressed.
