BACKGROUND:Postoperative acute mental disorders refer to patients without mental disorders suffer from neurological dysfunction after surgery. OBJECTIVE:To analyze the association between psychological resilience and postoperative acute mental disorders after total knee arthroplasty (TKA). METHODS:Convenience sampling, the Chinese Version of Connor and Davidson's resilience scale (CD-RISC), was used to measure the levels of psychological resilience in 832 patients undergoing TKA. The questionnaire covered three dimensionstenacity, self-improvement and optimism. The incidence of postoperative acute mental disorders was observed after operation. RESULTS AND CONCLUSION:(1) The CD-RISC scores of the patients with TKA surgery were (57.64±10.07), lower than the average scores of the elderly community in China. 20 (2.4%) patients had postoperative acute mental disorders. (2) Pearson correlation analysis demonstrated the negative correlation between the levels ofresilience and the incidence of postoperative acute mental disorders (r=-2.43, P<0.05). (3) Patients with lower psychological resilience levels had a higher incidence of postoperative acute mental disorders. Developing psychological resilience may become an important strategy to reduce the occurrence of postoperative acute mental disorders.
