The patient was a 68-year-old female. She has been on conservative treatment for right knee osteoarthritis for five years.<BR>X-ray showed severe bone loss of her medial tibial condyle. We performed total knee arthroplasty using a 5 mm augmentation block to the medial tibial condyle. However, X-ray showed the loosening and sinking of the tibial component seven months after the operation. We performed revision total knee arthroplasty using a 10 mm augmentation block and long-stem. When treating such cases of severe bone loss of the tibial codyle, MRI is useful for the evaluation of the area of the osteonecrosis. Surgery must also be planned to complete resection of the osteosclerotic area inclusing osteonecrosis."},{"@language":"ja","@value":"脛骨内側顆骨壊死様病変の進行，骨欠損を伴う膝関節症に対し，人工膝関節置換術（以下TKA）を施行後，術後早期に沈下をきたした一例について他の同様の病変に対するTKA症例と比較検討し，考察を加え報告する．症例は68歳，女性．平成11年10月頃より右膝痛増強，変形高度にてTKAを施行した．術後経過は良好であったが，術後6ヶ月頃より右下腿痛が出現し，脛骨コンポーネントの沈下ならびに内反増強を認めた．安静でも症状軽減せず，術後10ヶ月時にlong stemを使用した再置換術施行した．その後の経過は良好である．骨壊死様病変例では術前評価としてMRIによる骨壊死範囲の推定は有意義であり，手術時壊死部を完全に切除し，脛骨ブロックやlong stem使用の必要性等を検討する必要があると考えられた．"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410853647369755394","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000257878941"},{"@type":"NRID","@value":"9000014168031"}],"foaf:name":[{"@language":"en","@value":"Matsubara Hirokazu"},{"@language":"ja","@value":"松原 弘和"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Orthopedic Surgery Kyushu Kosei Nenkin Hospital, Fukuoka, Japan"},{"@language":"ja","@value":"九州厚生年金病院整形外科"}]},{"@id":"https://cir.nii.ac.jp/crid/1410853647369755393","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000257878942"},{"@type":"NRID","@value":"9000000841102"}],"foaf:name":[{"@language":"en","@value":"Yamaguchi Tomotaro"},{"@language":"ja","@value":"山口 智太郎"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Orthopedic Surgery Kyushu Kosei Nenkin Hospital, Fukuoka, Japan"},{"@language":"ja","@value":"九州厚生年金病院整形外科"}]},{"@id":"https://cir.nii.ac.jp/crid/1410853647369755392","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000257878943"},{"@type":"NRID","@value":"9000005798671"}],"foaf:name":[{"@language":"en","@value":"Kawamura Hideya"},{"@language":"ja","@value":"川村 秀哉"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Orthopedic Surgery Kyushu Kosei Nenkin Hospital, Fukuoka, Japan"},{"@language":"ja","@value":"九州厚生年金病院整形外科"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00371033"},{"@type":"EISSN","@value":"13494333"},{"@type":"NCID","@value":"AN00126582"}],"prism:publicationName":[{"@language":"en","@value":"Orthopedics & Traumatology"},{"@language":"ja","@value":"整形外科と災害外科"},{"@language":"en","@value":"Orthopedics & Traumatology"},{"@language":"ja","@value":"整形外科と災害外科"}],"dc:publisher":[{"@language":"en","@value":"West-Japanese Society of Orthopedics & Traumatology"},{"@language":"ja","@value":"西日本整形・災害外科学会"}],"prism:publicationDate":"2008","prism:volume":"57","prism:number":"1","prism:startingPage":"18","prism:endingPage":"20"},"reviewed":"false","url":[{"@id":"https://search.jamas.or.jp/link/ui/2008182503"}],"availableAt":"2008","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=total%20knee%20arthroplasty","dc:title":"total knee arthroplasty"},{"@id":"https://cir.nii.ac.jp/all?q=osteonecrosis","dc:title":"osteonecrosis"},{"@id":"https://cir.nii.ac.jp/all?q=long%20stem","dc:title":"long stem"},{"@id":"https://cir.nii.ac.jp/all?q=magnetic%20resonance%20imaging","dc:title":"magnetic resonance imaging"},{"@id":"https://cir.nii.ac.jp/all?q=%E4%BA%BA%E5%B7%A5%E8%86%9D%E9%96%A2%E7%AF%80%E7%BD%AE%E6%8F%9B%E8%A1%93","dc:title":"人工膝関節置換術"},{"@id":"https://cir.nii.ac.jp/all?q=%E9%AA%A8%E5%A3%8A%E6%AD%BB","dc:title":"骨壊死"},{"@id":"https://cir.nii.ac.jp/all?q=%E3%83%AD%E3%83%B3%E3%82%B0%E3%82%B9%E3%83%86%E3%83%A0","dc:title":"ロングステム"},{"@id":"https://cir.nii.ac.jp/all?q=%E7%A3%81%E6%B0%97%E5%85%B1%E9%B3%B4%E6%98%A0%E5%83%8F%E6%B3%95","dc:title":"磁気共鳴映像法"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1571417125696512128","@type":"Article","relationType":["cites"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Bone defects in revision total knee arthroplasty : classification and management"}]},{"@id":"https://cir.nii.ac.jp/crid/1571417125696515968","@type":"Article","relationType":["cites"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Management of bone loss : augments, cones, offset stems"}]},{"@id":"https://cir.nii.ac.jp/crid/1571698600673220096","@type":"Article","relationType":["cites"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Spontaneous osteonecrosis of the knee : the result of subchondral insufficiency fracture"}]},{"@id":"https://cir.nii.ac.jp/crid/1571980075649935104","@type":"Article","relationType":["cites"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Treatment options of bone defects in revision of total knee replacement"}]},{"@id":"https://cir.nii.ac.jp/crid/1572543025603352064","@type":"Article","relationType":["cites"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Osteonecrosis-like syndrome of the medial tibial plateau can be due to a stress fracture.
