We report 6 cases of dislocation of total knee arthroplasty (TKA). We identified 2 patterns of instability in the sagittal plane, one with posterior translation of the tibia, occurring mainly in the postoperative period and usually resulting from a trauma, and the other with anterior translation of the tibia, occurring 6 months to 7 years postoperatively and with no preceding trauma. In the latter group, instability was manifested gradually as a lengthening of the posterior cruciate ligament and the posterior capsule, leading to a recurvatum deformity of the knee.
我们报告了6例全膝关节置换术（TKA）脱位的病例。我们在矢状面确定了2种不稳定模式，一种是胫骨后移，主要发生在术后，通常由创伤引起；另一种是胫骨前移，发生在术后6个月至7年，且无先前创伤史。在后一组中，不稳定逐渐表现为后交叉韧带和后关节囊延长，导致膝关节反屈畸形。
