is a benign and a rare pathology. It is defined as an acute or chronic inflammation of infrapatellar fat [1,2]. It is a differential diagnosis of anterior knee pain, which is not obvious because of the absence of specific signs. In many developing countries, the technical platform is limited and patients can not benefit from the universal health care system coverage. We present a case of Hoffa's disease so that practitioners practicing in our context can pay particular attention to cases of chronic gonalgia not responding in to the usual analgesics. Miss B. B. is 19 years old, who consulted for chronic bilateral knee pain without the notion of trauma. An MRI of the knees showed Hoffa disease at the proximal patellar, and sub-quadricipital bursitis with minimal femoro-tibial effusion without meniscal injury. She have had a series of 3 glucocorticoid infiltrations and physiotherapy sessions, which alleviated the pain, and allowed her to fully recover the functioning of her lower limbs. A favorable evolution was observed with a decline in 6 months. Clinical surveillance every 6 months has been instituted. There are many pathologies wich are manifested by pain in the anterior part of the knee. Hoffa's disease, although benign, can be very debilitating. It is important to think of it when faced with chronic gonalgia which is difficult to diagnose and refere the patient to a referal hospital in order to avoid wrong diagnosis.
