Some of the reasons that the revision TKAs were required were loosening of the three joints (three knees), instability of the joints (two knees), or fracture of the tibial component (one knee). Pre-revision implants included cruciate retaining type (CR-type) implants for six of the knees and posterior stabilizer type (PS-type) implants in two of the knees. Two CR-type prostheses, three PS-type prostheses and three rotating hinge type prostheses were used for the revision TKA. Bone defects were identified in four of the tibiae. Modular metal augments were used to fill each area of bone loss in three of the knees,whereas bone cement was used in one joint.}, pages = {96--101}, title = {人工膝関節再置換術の経験}, volume = {26}, year = {2007}, yomi = {サイショ, コウイチロウ and ウチダ, ヒデホ and ムラカミ, ヒロシ and アリズミ, ユウイチ and トトリベ, コウジ and チョウサ, エツオ} }
