Abstract
Numerous anatomical variants are described around the knee, many of which look like
bony lesions, so it is important to know them to avoid unnecessary complementary tests
and inadequate management. Likewise, several alterations in relation to normal development
can also simulate bone lesions.
However, numerous pathologic processes frequently affect the knee, including traumatic,
inflammatory, infectious, and tumor pathology. Many of these entities show typical
radiologic features that facilitate their diagnosis. In other cases, a correct differential
diagnosis is necessary for proper clinical management.
Despite the availability of increasingly advanced imaging techniques, plain radiography
is still the technique of choice in the initial study of many of these pathologies.
This article reviews the radiologic characteristics of tumor and nontumor lesions
that may appear around the knee to make a correct diagnosis and avoid unnecessary
complementary radiologic examinations and inadequate clinical management.
