Cysts of Hoffa's ligament are exceptional. Twelve cases have been reported in the literature, two of which were treated arthroscopically. We report the first case in the French literature. A 21-year-old woman developed an atypical cystic formation of the knee. The diagnosis of ganglion cyst of Hoffa's ligament was strongly suggested at magnetic resonance imaging and confirmed at arthroscopy. We recall the different epidemiologic, pathogenic, clinical and radiological aspects of this condition and emphasize the importance of MRI for the differential diagnosis with other tumors.

    • "However, the recurrence of ganglia after arthroscopic treatment has been reported with cyst reformation [14]. In such cases, the recurrence risk is high; therefore, patients should be followed up more carefully [15]. "

    ABSTRACT: Large ganglionic cystic formations arising from the infrapatellar fat pad are quite uncommon and only a few are mentioned in the literature. An open excision in these cases is mandatory. We report the case of a large infrapatellar fat pad ganglion in a 37-year-old Greek man with chronic knee discomfort. The ganglionic cyst originated from the infrapatellar fat pad and had no intrasynovial extension. The final diagnosis was determined with magnetic resonance imaging of the knee, and the lesion was treated with surgery. These lesions are asymptomatic in most cases but often are misdiagnosed as meniscal or ligamentous lesions of the knee joint. Nowadays, the therapeutic trend for such lesions is arthroscopic excision, but when there is a large ganglion, as in this case report, the treatment should be an open and thorough resection. This report is intended mostly but not exclusively for clinical physicians and radiologists.

    ABSTRACT: Ganglion cysts of the knee are extremely uncommon. They usually cause non-specific symptoms and do not produce classical signs. Advances in imaging techniques as well as widespread use of arthroscopy have made detection of these cysts easier, and most can be treated arthroscopically. Ganglion cysts arising within the infrapatellar fat pad are even more uncommon. We report a case of a young lady with a giant intra-articular ganglion within the infrapatellar fat pad that was treated by open excision.
