The Impact of Preoperative Education on Knee and Hip Replacement: A Systematic Review

This review aims to evaluate the usefulness of preoperative education in the orthopedic patient undergoing knee and total hip replacement. The systematic review was conducted by searching the PubMed, Cochrane, CINAHL, and Embase databases from inception to April 2021. Keywords and combinations of keywords were organized according to the PICOs approach to identify relevant studies. Thirty-seven studies involving 5185 patients were included. Preoperative education was associated with decreased postoperative pain compared to the control group. Preoperative anxiety and length of stay were reduced in most studies through preoperative education compared to the control group. Furthermore, other topics such as sleep, mental status, compliance, knowledge, and patient expectations generally showed improvement in the experimental group. For future investigations, it would be imperative to augment the patient sample size to enhance the research’s reliability and incorporate the most up-to-date literature.
