Poster 277: Return to Sport after Multi-Ligament Knee Injury in Young Athletes

Objectives: While return to sport (RTS) has been well studied in young athletes after anterior cruciate ligament (ACL) reconstruction, there is a paucity of literature on RTS following reconstructive surgery for multi-ligament knee injury (MLKI). The purpose this study assess level MLKI 23 years old or younger at the time and evaluate factors associated with RTS. Methods: This was retrospective study. We identified 116 patients our Level 1 referral center who sustained an age younger. All underwent operative reconstruction. Patients were contacted via mail then completed surveys by telephone if willing participate. Our primary outcome variable self-reported ability their preoperative higher surgery. Secondary variables included 2000 International Knee Documentation Committee Subjective Form (2000 IKDC-SF), ACL Return Sport After Injury (ACL-RSI), Short-Form 12 (SF-12) physical mental health scales. Dependent age, participation cutting sports, number specific ligaments injured, any concurrent diagnoses. Results: A total 30 (25.9%) average follow-up 7.8 postoperatively (24 male, 6 female, 18.1±2.5 injury). Of cohort, 90% returned some level, while 43.3% higher. Participation sports significantly lower rate same (p=0.017). Higher IKDC-SF ACL-RSI scores (p=0.001 0.002, respectively). participated preoperatively demonstrated odds ratio (OR) returning athletic (OR=3.516 [1.034-11.955]; p=0.044). Number injury, diagnosis, SF-12 not statistically significant change MCL injuries trended toward than two- three-ligament involving PCL and/or LCL, but (50% vs. 25%, p=0.225). Conclusions: high percentage MLKI, less half previous level. Those participating likely pre-injury MLKI. OR reported IKDC-SF. There no difference those based scores, presence injury. Future studies will focus larger cohorts modifiable obtain functional sport. [Table: see text][Table: text]
