Abstract:

BACKGROUND: The knee joint acts as the body’s largest and most complex joint, which is a commonly seen perplex in patients because of synovium and cartilage diseases. Moreover, clinical physicians are often confused on the ultrasonic diagnosis of synovium and cartilage diseases.
OBJECTIVE: To review the ultrasound misdiagnosed cases of knee cartilage and synovial lesions and to summarize the common misconceptions and discrimination methods.
METHODS: A retrospective analysis was performed in the ultrasound misdiagnosed cases of knee cartilage and synovial lesions reported from 2002 to 2014, and then the common misconceptions and corresponding identification methods were summarized.
RESULTS AND CONCLUSION: High-frequency ultrasound is most likely to have six “mistaken ideas” addressing knee cartilage and synovial lesions: (1) cartilage degeneration; (2) synovial calcification; (3) echo intensity from synovial lesions; (4) blood flow in the synovium; (5) synovial effusion; (6) lesions involving intraarticular structures. High-frequency ultrasound runs through dynamical observation and contrast observation of bilateral knee joint lesions, which is a valuable imaging method for diagnosis of cartilage and synovial diseases based on vigilance at the “mistaken ideas” and mastery of the distinguishing ideas and methods.
