Learning objectives To review the basic anatomy of Hoffa’s fat pad including its neurovascular supply. To discuss the various abnormalities associated with Hoffa’s fat pad. To demonstrate the imaging features of Hoffa’s fat pad lesions. 
Read more Background Hoffa’s fat pad (HFP) may be involved in various pathologies and present as one of the causes of anterior knee pain due to its rich nerve supply. While these pathologies are commonly seen on MRI, it is essential to be aware of the wide range of normal variants and pathologic conditions affecting the HFP and their clinical significance. 
Read more Findings and procedure details This exhibit discusses the must know details about the normal anatomy, variants and common pathologies involving the HFP with some key example cases.  Firstly, it is essential to be aware of the normal anatomy and normal variants of HFP. The Hoffa’s (infrapatellar) fat pad is a soft tissue structure in the knee that is highly vascularized and innervated. It has adipocytes and connective tissues and acts as a protective layer that separates the patella from the thigh and shin bones. Vascular supply...
Read more Conclusion HFP is richly innervated resulting in significant pain caused by an abnormality, which usually present as knee pain. MRI helps to diagnose and differentiate among various pathologies. Knowledge of basic anatomy of HFP and its lesions is crucial in diagnosis which can alter the clinical approach, management and prognosis.
