After 40 days intra-articular injury, risk profile increases linearly with time to surgery in adolescent patients undergoing primary anterior cruciate ligament reconstruction.

Purpose: Anterior cruciate ligament (ACL) injuries are becoming more common in youth athletes. Time-to-surgery has been shown to significantly affect the rates of concurrent injuries at the time of ACL reconstruction (ACLR). The purpose of this study was to evaluate if time-to-surgery in ACLR impacts observances of intra-articular injuries and to categorize injury profile in relation to time.

Skeletal Maturity Is Associated With Increased Meniscal and Chondral Pathology in Patients Under 21 Years of Age Undergoing Primary Anterior Cruciate Ligament Reconstruction Within 6 Months of Injury.

Purpose: To compare injury profiles of meniscal and/or chondral injury in skeletally mature (SM) with immature (SI) patients undergoing primary anterior cruciate ligament reconstruction (ACLR).

Methods: Current Procedural Terminology code 29888 was queried from January 2012 to April 2020. Patients younger than 22 years who underwent primary ACLR within 6 months of injury were included.

Improving Academic Performance, Belonging, and Retention through Increasing Structure of an Introductory Biology Course.

Integration of active-learning approaches into increased-structure postsecondary classrooms significantly improves student academic outcomes. We describe here two parallel sections of Introductory Biology that shared learning objectives and content but varied in course structure. The large-enrollment traditional course consisted of four 50-minute lectures coupled with minimal active-learning techniques, while an increased-structure intervention course integrated multiple active-learning approaches, had limited enrollment, and comprised three 50-minute lectures combined with a fourth peer-led team-learning discussion section.
