Abstract

Suprapatellar synovial plica with complete septum is a relatively rare disease, but it sometimes causes anterior knee pain, suprapatellar swelling, and flexion disorder in young people. We report three cases of this disease, in which the suprapatellar bursa and knee joint were completely separated by the septum. All cases were young or middle aged female and they had anterior knee pain and swelling which were localized in suprapatellar pouch. Two of them had limited range of motion under 90°. T2-weighted MRI revealed synovial plica, seen as bands of low signal intensity within the high-signal intensity joint fluid in all cases. Rest and injection therapy were not effective. However arthroscopic synovectomy and resection of the septum successfully cured their symptoms and no recurrence was observed.
