Abstract

Purpose

To identify the incidence of lateral meniscal oblique radial tears (LMORTs) concomitant with anterior cruciate ligament (ACL) tears in pediatric patients undergoing ACL reconstruction.

Methods

A single-center retrospective cohort design was used to analyze all patients 18 years and younger undergoing ACL reconstruction between July 2017 and February 2023. Operative notes and intraoperative arthroscopic photos were analyzed to determine the incidence of LMORTs. Two independent observers reviewed the images and reached agreement on LMORT incidence and classification of each tear. Demographic, clinical, and outcomes data were collected and analyzed.

Results

Lateral meniscal oblique radial tears were identified in 19 of 310 (6.13%) adolescent and pediatric ACL reconstruction cases. Of these patients, 68.4% were male. All but one patient had signs of lateral meniscus injury on preoperative magnetic resonance imaging. Of the LMORT patients, 7 (37%) had a type 1 tear, 1 (5%) had a type 2 tear, 7 (37%) had a type 3 tear, and 4 (21%) had a type 4 tear.
