Psychological Responses Among Individuals Undergoing Anterior Cruciate Ligament Reconstruction Surgery

This study elucidated how previous surgery experience, coping, and optimism influenced the mood of patients who underwent anterior cruciate ligament (ACL) reconstruction surgery. Additionally, it examined the relationships among age, preoperative mood, and postoperative mood. Sixty-four patients (n = 42 men, n = 22 women; age range = 18-51 y) who underwent ACL reconstruction surgery at one hospital in western Japan completed questionnaires before and after surgery. Results revealed that patients who underwent previous ACL reconstruction surgery reported higher tension-anxiety (P < .01) and total mood disturbance (TMD) (P < .05) than did patients who underwent primary surgery. Additionally, tension-anxiety, anger-hostility, TMD (P < .001), depression-dejection, fatigue, and confusion (P < .01) assessed before surgery were significantly reduced after surgery, and preoperative mood was positively related to postoperative mood. Furthermore, positive interpretation was negatively related to TMD before surgery (P < .05), and evading one's responsibility was positively related to TMD after surgery (P < .05). Therefore, psychological support might be necessary for patients who underwent previous ACL reconstruction surgery and patients who evade responsibility. The results of this study will help sport medicine professionals identify several individual factors that are related to psychological responses of patients who underwent ACL reconstruction surgery.
