Association of Grit With Postoperative Knee Outcomes and Physical Function After ACL Reconstruction in Adolescent Athletes.

Background: Grit is the disposition to strive for long-term goals despite setbacks and challenges. Given the lengthy, arduous process of rehabilitation after anterior cruciate ligament reconstruction (ACLR), an athlete's grit may predict postoperative outcomes across time.

Purpose/hypothesis: The primary aim of the study was to evaluate the relationships between baseline (preoperative) grit and postoperative knee outcomes across the year after ACLR among adolescents.
