en تروما Trauma گزارش مورد Case Report <div style="text-align: justify;"><span style="font-size:14px;"><span style="font-family:Tahoma;"><span style="line-height:2;">Neglected knee dislocations are rare. There is no agreement on the best treatment for these injuries. In this report, we present a case of old knee dislocation treated with open reduction and proximal tibial traction pin. After open reduction and extensive soft-tissue release, the complete reduction was not achieved. Therefore, we used a proximal tibial traction pin to gradually obtain a complete reduction via &lrm;traction weight change.&lrm; We did no ligamentous repair. One year after the operation, the patient had an acceptable radiographic reduction and satisfactory clinical outcomes. We recommend the proximal tibial traction pin as a valuable alternative in the treatment of neglected &lrm;knee dislocation. In addition to its promising outcomes, the traction pin is much less expensive than the already-used devices. Moreover, the introduced procedure makes the future conversion to total knee arthroplasty (TKA) more feasible, which is considered a significant concern in such &lrm;patients.&nbsp;</span></span></span></div> Old knee dislocation, Soft-tissue release, Traction pin 181 186 http://jros.iums.ac.ir/browse.php?a_code=A-10-1030-1&slc_lang=en&sid=1 Hooman Yahyazadeh yahyazadehhooman@yahoo.com 10031947532846006676 10031947532846006676 No Department of Orthopedics, Bone and Joint Reconstruction Research Center, School of Medicine, Iran University of Medical Sciences, Tehran, Iran.
