Poster 347: PSYCHOLOGICAL READINESS AFTER REVISION ACL RECONSTRUCTION: A ROAR STUDY

Objectives: Background: Revision ACL reconstruction (ACLR) has demonstrated worse functional outcomes and higher reinjury rates in young patients. Psychological associations with revision surgery have not previously been evaluated. Purpose: To investigate levels of psychological readiness stress patients after ACLR Methods: Patients, ages 10-35, were enrolled who underwent at one center by six surgeons. was assessed 6-months post- operatively the Anterior Cruciate Ligament Return to Sport After Injury (ACL-RSI) PROMIS- Stress Experiences (PROMIS-PSE), respectively. The International Knee Documentation Committee (IKDC/Pedi-IKDC), Hospital for Special Surgery Pediatric Functional Activity Scale (HSS Pedi-FABS) also collected. Patient reported compared a cohort primary Propensity score matching 3:1 performed age, sex, graft type. Results: Matching resulted 81 (57 24 revision). Mean age group 18.6 ± 3.2 (66.7% female). most common type both BTB (65% 67%, respectively) (Table 1). Mild negative correlation detected between IKDC PROMIS PSE (r=-0.31; 95% CI=-0.49, -0.10; p=0.005) moderate positive ACL-RSI scores (r=0.56; CI=0.39, 0.70; p<0.001). had lower (47 vs. 64, p=0.004) IKDC/Pedi-IKDC (72 vs 78, p=0.05), longer return sports clearance (median, 10 months 8 months; p=0.02). Regression analysis showed could expect 15-point decrease RSI (95% CI=-25.30, -4.21; p=0.007). Furthermore, 1.4 month date CI=0.29, 2.60; p=0.01). No differences noted Pedi- FABS or PROMIS-PSE 2). Conclusions: This study is first examine sport ACLR. At post-surgery, scores, inferior knee delayed clearance. Greater attention aspects recovery setting may be important help optimize post-operative care outcomes. [Table: see text][Table: text]
