摘要


評估影像檢查對診斷滑膜皺襞與皺襞病變之能力。 回溯過去三年間本院對317位患者的410個膝關節所做的350例關節攝影術,200例電腦斷層關節攝影術,和60例磁振造影術,以評估各種影像檢查診斷滑膜皺襞之存在、位置與滑膜皺襞病變之能力。 我們發現,髕骨下皺襞很少在影像檢查中見到,只有三例前十字韌帶斷裂的病人,可在側位關節攝影術中見到。髕骨上皺襞共有374例(91.2%),大多是沒有症狀的。僅有一例完全性髕骨上皺襞合併慢性出血性髕骨上黏液囊炎及三例不完全性髕骨上皺襞合併局部髕骨上黏液囊炎被發現。髕骨內側皺襞有95例(23.2%),可輕易地在軸切面之關節攝影術、電腦斷層關節攝影術以及併有關節積水之磁振造影術中發現。十八例經由影像診斷為髕骨內側皺襞症候群之病人,後均由關節鏡或關節切開術證實。 隨著影像技術的進步,滑膜皺襞和皺襞症候群可輕易地經由非侵襲性的磁振造影術,或稍具侵襲性的關節攝影術或電腦斷層關節攝影術診斷出來,作為手術前的評估。

To establish the capability of imaging diagnosis of synovial plicae and plica syndrome, we retrospectively reviewed 350 double-contrast arthrograms, 200 computed arthrotomograms (CT-arthrograms), and 60 magnetic resonance (MR) examinations in 410 knees of 317 patients. The presence, location, and pathological findings of synovial plicae were evaluated. The observations were correlated with operative and/or arthroscopic findings. The suprapatellar plicae were present in 374 (91.2%) knees, the medial patellar plicae in 95 (23.2%) knees, the infrapatellar plicae in 3 knees, and the lateral patellar plica in 1 knee. Suprapatellar plicae can be complicated by chronic hemorrhagic bursitis (complete type plica, n=1 knee), osseous body entrapment (incomplete type plica, n=1 knee), or focal suprapatellar bursitis (incomplete type plicae, n=3 knees). Eighteen knees had pathological medial plicae complicated by medial plica syndrome. With advancement of imaging techniques, synovial plicae and plica syndrome can be easily demonstrated and diagnosed prospectively by noninvasive MR imaging or mildly invasive arthrography and CT-arthrography.
