To give a narrative overview of meniscal tears with a radiologic emphasis on the morphologic type, technical considerations, and on the relevance of the type of meniscal tear in the context of osteoarthritis ({OA}) research.
Design
Total 20 years of the {PubMed} database were searched for epidemiological, radiological, arthroscopic and biomechanical reports, and review articles focusing on meniscal tears in middle-aged and older individuals, in the setting of {OA}. Case reports, publications on meniscal tears in young active individuals, and publications not in English were excluded.
Results
Meniscal intra-substance signal abnormalities are associated with an increased risk of a degenerative meniscal tear in the same segment. Posterior radial tears of the medial meniscus appear to be a highly relevant event in {OA} of the knee, with associated cartilage loss and meniscal extrusion. Radial tears are more commonly missed on {MRI} than other types, and should be carefully looked for on coronal and axial images. While medial meniscus posterior root tears are of “radial” morphology, there is growing interest in looking at them as a separate entity, mainly because they require a different therapeutic approach.
Conclusion
There is a lack of data on the relevance of different morphologic types of meniscal tears to the natural history of knee {OA}, both cross-sectionally and—especially—longitudinally. Further epidemiologic studies should focus on specific meniscal tears based on their morphology to better understand their relevance in the genesis and progression of knee {OA}.},
