Characterization of Common Knee Joint Diseases using Magnetic Resonance Imaging among Saudi Population

Objective: To characterize common knee joint diseases using Magnetic Resonance Imaging among Saudis population, to find out the most common disease in knee joint, demonstrate the diagnostic value of MRI in diagnosing presence and absence of this disease and identify whether MRI can lead to accurate diagnoses of Knee joint disease. Methods: The study was a retrospective study of MRI finding in common knee joint diseases, A total of 50 patients were investigated by MRI machine across different Hospitals Department of Radiology Jeddah State, Saudi Arabia from September 2018 to December 2018. The problem of the study was increasing in patients suffering from knee joint pain. Results: Among 50 patients data was classified and analyzed using excel, and found that meniscus tear is the most common knee joint disease with a prevalence of 30 % and 14 % for osteoarthritis changes and also found that males (56 %) were more affected than females (44 %), and the age group of (36-50) and (51-65) were more exposed to knee joint disease. Conclusion: MRI scan is a good non-invasive tool and can be used as first line imaging modality for knee joint diseases. The MRI is the modality of choice in diagnosing internal lesions of the knee with high details and showed that meniscus tear had the highest prevalence of the knee pathological change, the result found meniscus tear had higher percentage and found a relation between patients age and OA changes and Backer Cyst of the knee joint and there is significant relationship between patient gender and incident of knee disease.
