Background: Imaging of knee joint to detect joint disorder using magnetic resonance imaging (MRI) is an efficient tool and safest one. Purpose: The current research was conducted to compare between two MRI machines with different magnetic field strength for detection knee lesion.100 images was done at King Fiasal hospital at Taif city KSA from mid-February till mid-March 2019, special data collection sheet was designed to record patient gender and ages as well as protocol for each knee examination. Results: From the 100 images there were 15 images that diagnosed as normal cartilage and lesion detected, more frequent women patient was detected compared to male patients (60% and 40% respectively. The most common age of patients was 51-60 years, 3.0 Tesla (T) MRI machine was more sensitive in detection of knee cartilage lesion than 1.5T. 3T give better signal to noise ratio and better resolution with large matrix size. Conclusion and recommendations; MRI at 3.0 T improved visualization of anatomical structures and improved diagnostic confidence compared to 1.5 T. More study are required to detect specificity and accuracy as well as phantoms based study, to establish local protocol for imaging knee that compatible with our local society
