Rotator cuff injury in the pediatric population: a systematic review of patient characteristics, treatment, and outcomes.

Abstract

Rotator cuff injuries (RCIs), traditionally thought to be an adult-type pathology, have been reported in the pediatric population, but there remains limited evidence regarding this injury pattern in pediatric patients. The purpose of this study was to systematically review the literature to characterize the epidemiology, injury patterns, treatment modalities, and outcomes for pediatric patients with RCIs. A systematic review was performed in accordance with Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, reviewing Pubmed, Embase, Cochrane, and CINAHL databases. Studies reporting imaging confirmed RCIs, and treatment outcomes in patients less than 18 years of age were included. Patient demographics, mechanism, injury type, and injury location were recorded. Treatment type and patient outcomes were abstracted when available and summarized with descriptive statistics. Our search identified 28 studies published from 1994 to 2020, which included 215 total tendons injured in 185 patients. Twenty-six studies were classified as level IV evidence, whereas only two were level III. When described, the most injured tendon ( n = 184) was the supraspinatus, whereas the most described injury type ( n = 215) was a partial tear. Surgical intervention was pursued in 75.8% of injuries, with arthroscopy being more common than open repair (79.4% vs. 20.6%). Nonoperative treatment was primarily utilized for partial tears. Among the 24 studies reporting on return to sports, nonoperatively managed patients returned later than those treated operatively (mean: 10.7 vs. 7 months). Only eight studies included patient reported outcome measures (PROMs), and just five had pre- and posttreatment scores. Three complications were noted, all in operative patients. RCIs in pediatric patients have been reported in the literature with increasing frequency over the last decade, but the quality of evidence remains poor with inconsistent injury descriptions and outcome reporting. Excellent results were seen for all injury types and locations with both operative and nonoperative treatments. The literature for pediatric RCIs remains limited in guiding management decisions indicating a need for more high-quality studies to compare outcomes across injury and treatment type. Level of evidence: level III.
