Learning objectives The purpose of this educational poster is to: Delineate knee fat pad anatomy and pathology by presenting a structured, imaging-based approach to identify normal anatomy versus pathology. Provide a simplified yet comprehensive classification system that allows rapid categorization of lesions. Introduce a step-wise diagnostic workflow that is tailored for routine radiology practice and helps in arriving to the diagnosis quicker and more efficiently. Offer a quick MRI signal correlation key that links sequence-specific findings with probable differential diagnoses. Present a single-glance overview of major fat...
Read more Background  The knee joint contains three primary anterior fat pads: the infrapatellar (Hoffa’s) fat pad, located behind the patellar tendon; the quadriceps fat pad, situated superior to the patella; and the prefemoral fat pad, which lies deep to the quadriceps tendon against the distal femur. These structures serve as flexible buffers that accommodate joint movement while housing essential neurovascular and synovial elements. Hoffa’s fat pad is an intracapsular yet extrasynovial structure located posterior to the patellar tendon and anterior to the...
Read more Findings and procedure details The poster is structured into intuitive, visually guided sections to facilitate easy navigation and rapid learning:  Anatomy and Functional Overview [fig]1 Describes anatomical overview of the anterior knee structures and the various layers of anterior knee. A figure depicting the three knee fat pads in lateral radiograph, CT and MRI is also depicted with brief mention of other adjacent fat pads.[fig]2 shows detailed anatomical description of Hoffa’s fat pad, including boundaries, vascular supply, innervation, fibrous condensation and synovial clefts.Knee fat...
Read more Conclusion Knee fat pad lesions represent a niche yet clinically significant domain in musculoskeletal imaging, with limited consolidated literature and frequent diagnostic ambiguity. This educational poster hopes to address this gap by providing clear, practical, and visually intuitive cues that aid in efficient diagnosis. By combining the optimized classification system, step-wise diagnostic workflow, MRI signal correlation keys, and single-glance pathology summaries, this poster aims to serve as a real-world reporting aid, helping reduce missed or misclassified lesions, and ultimately contribute to...
