Abstract
BackgroundThe evidence supporting best practice guidelines in the field of cartilage repair of the ankle is based on both low quality and low levels of evidence. Therefore, an international consensus group of experts was convened to collaboratively advance toward consensus opinions based on the best available evidence on key topics within cartilage repair of the ankle. The purpose of this article is to report the consensus statements on “terminology for osteochondral lesions of the ankle” developed at the 2019 International Consensus Meeting on Cartilage Repair of the Ankle. MethodsForty-three international experts in cartilage repair of the ankle representing 20 countries were convened and participated in a process based on the Delphi method of achieving consensus. Questions and statements were drafted within four working groups focusing on specific topics within cartilage repair of the ankle, after which a comprehensive literature review was performed, and the available evidence for each statement was graded. Discussion and debate occurred in cases where statements were not agreed on in unanimous fashion within the working groups. A final vote was then held, and the strength of consensus was characterised as follows: consensus, 51%–74%; strong consensus, 75%–99%; unanimous, 100%. ResultsA total of 11 statements on terminology and classification reached consensus during the 2019 International Consensus Meeting on Cartilage Repair of the Ankle. Definitions are provided for osseous, chondral and osteochondral lesions, as well as bone marrow stimulation and injury chronicity, among others. An osteochondral lesion of the talus can be abbreviated as OLT. ConclusionsThis international consensus derived from leaders in the field will assist clinicians with the appropriate terminology for osteochondral lesions of the ankle.
Highlights
The description of cartilage injuries in the ankle have evolved over the past several centuries
Question: What is the definition of an isolated osseous lesion, and what is the appropriate terminology and acronym? Answer: The definition of an isolated osseous lesion is a bony/subchondral defect absent of Journal Pre-proof any cartilaginous/chondral injury
The appropriate terminology is a subchondral bone lesion, which can be abbreviated as SBL
Summary
The description of cartilage injuries in the ankle have evolved over the past several centuries. The current body of evidence in the field of ankle cartilage repair is based on both low-level and low-quality of evidence.[12] The vast majority of studies are of level IV evidence, and consist of short-term follow-up time periods. An international, multidisciplinary group of experts was assembled to develop expert and evidence-based consensus statements to assist clinicians in following best practice guidelines. The purpose of this article is to report the results of the working group on Terminology that were developed at the 2019 International Consensus Meeting on Cartilage Repair of the Ankle. The evidence supporting best practice guidelines in the field of cartilage repair of the ankle are based on both low quality and low levels of evidence. The purpose of this article is to report the consensus statements on “Terminology for Osteochondral Lesions of the Ankle” developed at the 2019 International Consensus
