Most intra-articular ganglion cysts of the knee develop from the cruciate ligament or meniscus and rarely from the infrapatellar fat pad. We report two cases of arthroscopically resected ganglions arising from the infrapatellar fat pad. Case 1: A 24-year-old woman presented with anterior knee pain and a mass. Imaging revealed a diffuse multifocal mass anterior to the knee joint and a mass arising from the infrapatellar fat pad. Resection was performed, with no ganglion recurrence seen six months postoperatively. Case 2: A 61-year-old woman presented with anterior medial knee pain. Imaging revealed medial-type osteoarthritis changes at KL2 and a multifocal mass in the infrapatellar region. Resection plus tibial osteotomy was performed, with no ganglion recurrence observed two years postoperatively. In both cases, arthroscopic resection was performed, and no postoperative recurrence was observed. Arthroscopic resection of ganglions arising from the infrapatellar fat pad may be useful.
