Summary
Standardized MRI reporting for knee menisci is needed due to inconsistent terminology. Ten recommendations were developed to improve clarity and consistency in reporting meniscal anatomy and tears.
Area of Science:
- Radiology
- Orthopedics
- Medical Imaging
Background:
- Nomenclature variability in meniscal MRI reporting hinders consistent interpretation.
- Standardized reporting is crucial for accurate diagnosis and clinical decision-making.
Purpose of the Study:
- To evaluate nomenclature variability in MRI reporting of meniscal findings.
- To establish consensus recommendations for standardized MRI reporting of knee menisci.
Main Methods:
- A panel of musculoskeletal radiologists and orthopedic surgeons was convened.
- A systematic literature review was conducted to identify nomenclature inconsistencies.
- Consensus recommendations were developed based on literature analysis.
Main Results:
- Significant variability was found in terminology for meniscal anatomy, variants, tears, and associated findings.
- Inconsistencies included definitions of root zones, vascular zones, discoid meniscus criteria, tear grading, and interpretive labels.
- Ten consensus recommendations for standardized MRI reporting were formulated.
Conclusions:
- Descriptive anatomic language enhances reproducibility and clinical actionability over variable grading systems.
- Adopting the ten recommendations can reduce miscommunication and improve inter-institutional consistency.
- Standardized reporting supports more reliable clinical research and patient care.
