The management of isolated meniscal tears in skeletally immature children. An international expert consensus.

Abstract

Purpose: The prevalence and appreciation of meniscal tears in children have increased in both number and complexity. There is currently a paucity of high-quality evidence that can guide surgeons in treating skeletally immature patients with meniscal injuries. The aim of this study was to develop comprehensive recommendations for the management of isolated meniscal tears in skeletally immature children.

Methods: An international, two-round, modified Delphi consensus was completed. Included 'experts' were identified as having an established adult knee practice, including children and either: (1) Faculty at an international paediatric knee conference, (2) Active members of complex national paediatric multi-disciplinary groups or (3) Members of faculty on recognised national/international instructional courses aimed at teaching the management of meniscal lesions to knee surgeons. The currently available literature was reviewed, and areas of poor quality, inconclusive or absent evidence were examined and formed the focus of the study. A threshold of 70% was used to define consensus for our study based on other similar Delphi consensus studies in the literature.

Results: A total of 43 experts (Round 1) and 41 experts (Round 2) took part in the Delphi study, including surgeons from Europe, the United States of America and South America. 34 statements were identified exploring three main domains-clinical assessment, management and complex tears (bucket handle, discoid and radial). Following Round 1, consensus was reached on 17 (50%) statements; subsequently, after completion of Round 2, consensus was reached on 28 (82%) statements, leaving six (18%) with no consensus. The areas of no consensus included investigation of painless clicking, the most sensitive clinical test for meniscal pathology, treatment of small radial tears (less than 1/3 width), ability to reduce chronic bucket handle tears and timing of surgery.

Conclusions: This is the first modified Delphi consensus that provides evidence for surgeons treating skeletally immature children with isolated meniscal tears. A valuable level of consensus was reached on the assessment and management of simple and specialist meniscal tears. These consensus statements can both inform clinical practice and be used in the development of further high-quality research studies.

Level of evidence: Level V.
