Return to Sport and Re-Operation Rates in Athletes Under the Age of 20 Following Primary Anterior Cruciate Ligament Reconstruction: Risk Profile Comparing Three Patient Groups Predicated Upon Skeletal Age

摘要

Objectives:ACL injury in the skeletally immature athlete has become an increasingly significant clinical problem in recent years. The high-risk population of athletes less than 20 years of age has the lowest return to sport (RTS) rates and highest second surgery rates following ACL reconstruction (ACLR). The purpose of this prospective study is to evaluate the two-year clinical outcomes of three groups of primary ACLR in pediatric and adolescent athletes under the age of 20 based on skeletal age, school grade distribution and ACLR technique with a focus on RTS and incidence of second surgery. We hypothesize that the youngest (Group 1) and oldest (Group 3) cohorts will have lower revision ACL rates and higher RTS rates compared to the middle (Group 2) cohort of athletes.
