Synovial cyst formation resulting from nonabsorbable meniscal repair devices for meniscal repair

Several arthroscopic meniscal repair techniques and devices have been developed during the past decade. The Mitek Meniscal Repair System (Mitek, Ethicon, Norderstedt, Germany) is one of these devices. We report a case of synovial cyst formation after medial meniscus repair with a nonabsorbable Mitek Meniscal Repair System. The cyst in the right knee developed 5 months after the meniscus repair. After excision of the synovial cysts and removal of these devices, the mass and pain of the knee were relieved. To our knowledge, this is the first report of synovial cyst formation resulting from this device.
