Abstract The discoid lateral meniscus is often thicker and disc or saucer-shaped and more susceptible to tearing. The peripheral rim of the meniscus is more unstable and may be the reason for a higher rate of injury. MRI should be considered the standard for diagnosis. Symptomatic patients typically have meniscal tears. At imaging, these tears appear as degenerative damage or horizontal tears. Surgical intervention is only recommended for symptomatic patients. Patient age and the degree of tissue removed are the largest drivers regarding patient outcome. While acceptable clinical results were achieved around 10 years following surgery, 40% of patients developed degenerative changes in their knees.
