Over the 3 months before his admission, the swelling had become persistent and extended 10 cm proximal to the patella on the anterior aspect of the thigh. Magnetic resonance imaging revealed an enlarged suprapatellar pouch that was completely separated from the knee joint cavity by a suprapatellar membrane. Arthroscopic treatment consisted of complete removal of the membrane, creating a passage to the articular cavity, and debridement of the synovial calcifications. The patient was followed\u2010up postoperatively for 2 years and no recurrence of the swelling was reported during this period of time. Two potential mechanisms might have been responsible for the persistent swelling: (1) chondrocalcinosis led to effusion of a suprapatellar pouch that was originally isolated from the knee joint cavity, or (2) the suprapatellar pouch was separated from the knee joint cavity as a result of an incomplete involuted suprapatellar plica that became adherent during recurrent inflammation due to chondrocalcinosis.<\/jats:p>","DOI":"10.1053\/jars.2002.31698","type":"journal-article","created":{"date-parts":[[2002,8,24]],"date-time":"2002-08-24T23:46:10Z","timestamp":1030232770000},"page":"1-3","source":"Crossref","is-referenced-by-count":5,"title":["Chondrocalcinosis in an isolated suprapatellar pouch with recurrent effusion"],"prefix":"10.1002","volume":"18","author":[{"given":"Marcel","family":"Ziswiler","sequence":"first","affiliation":[{"name":"Balgrist University Hospital Z\u00fcrich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ernst\u2010Willi","family":"Rad\u00fc","sequence":"additional","affiliation":[{"name":"Balgrist University Hospital Z\u00fcrich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9","family":"Romero","sequence":"additional","affiliation":[{"name":"Balgrist University Hospital Z\u00fcrich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2002,3,1]]},"reference":[{"key":"e_1_2_2_2_1","first-page":"34","volume-title":"Arthroscopy of the knee","author":"Jackson RW","year":"1976"},{"key":"e_1_2_2_3_1","first-page":"507","article-title":"Ueber das strangartige Gebilde in der Kniegelenkhoehle (chorda cavi articularis genu)","volume":"21","author":"Mayeda T.","year":"1918","journal-title":"Mitt Med Fak Kaiserl Univ Tokyo"},{"key":"e_1_2_2_4_1","first-page":"513","article-title":"Arthroscopic study on lino's band (plica synovialis mediopatellaris)","volume":"50","author":"Sakakibara J.","year":"1976","journal-title":"J Jpn Orthop Assoc"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/036354657800600502"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/0749-8063(92)90008-Y"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(97)90207-3"},{"key":"e_1_2_2_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/0749-8063(90)90002-U"},{"key":"e_1_2_2_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/0749-8063(90)90063-J"},{"key":"e_1_2_2_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-197101000-00023"},{"key":"e_1_2_2_11_1","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1943.01220110121021"},{"key":"e_1_2_2_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/aja.1000860204"},{"key":"e_1_2_2_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/aja.1000860204"},{"key":"e_1_2_2_14_1","first-page":"149","article-title":"The anatomy of the joints.
