Synovial ganglia of the central pivot of the knee.
Five patients with intraarticular synovial ganglia of the knee were treated by arthroscopic surgery. These synovial cysts were found in the intercondylar fossa and appeared to originate from the cruciate ligaments. In 3 patients the ganglia were the only pathologic finding, solely responsible for the pain and functional impairment. In the other 2 patients the ganglia were accompanied by other intraarticular lesions. The diagnostic procedure (radiography, arthrography, CT, MRI, arthroscopy), confirmed the validity of CT scan and MRI in detection, differential diagnosis, and location of the ganglia in all cases. Arthroscopy enabled us to directly observe, biopsy, and remove the ganglia, resulting in immediate disappearance of symptoms and no relapse after a minimum follow-up of 20 months.
