Preoperative Psychological Competitive Ability Is Associated With Emotional States Six Months After Anterior Cruciate Ligament Reconstruction With Hamstring Autograft: A Prospective Study.

Abstract

Background Psychological state has been reported as one of the factors strongly related to a return to sports after anterior cruciate ligament (ACL) reconstruction. However, its relationship with the emotional state remains unclear. The aim of this study was to investigate whether patients who have undergone ACL reconstruction and have a higher preoperative psychological competitive ability have a better emotional status preoperatively and six months postoperatively. Methods Patients with a Tegner activity score of ≥6 who underwent ACL reconstruction between 2015 and 2020 were divided into two groups according to their grades on the Diagnostic Inventory of Psychological Competitive Ability for Athletes (DIPCA.3). The emotional states preoperatively and at six months postoperatively were assessed using the Profile of Mood States Second Edition (POMS2) and compared between the two groups. Furthermore, the possibility of returning to sports was compared between the groups based on participation in the entire practice at six months postoperatively. Results Eighty-four patients were included and divided into the high (DIPCA.3 grades ≥4, n = 23) and low (DIPCA.3 <4, n = 61) groups. Vigor-activity and friendliness were significantly higher in the high group than in the low group preoperatively. The difference was even greater at six months after ACL reconstruction. In addition, the high group showed significantly better results postoperatively for fatigue-inertia and total mood disturbance. Rates of return to sports did not differ significantly between the high and low groups (56.5% vs. 54.1%). Conclusions Those with a higher preoperative psychological competitive ability were in a positive emotional state preoperatively and six months after ACL reconstruction. However, the psychological competitive ability did not affect the rate of participation in the entire practice at six months postoperatively.
