Conversion of Fused Knee Following Distal Femur Tumor Surgery to Total Knee Arthroplasty
نویسندگان
چکیده
Conversion of knee arthrodesis to total knee arthroplasty is a difficult procedure accompanied by many complications due to soft tissue and extensor mechanism contracture and bone defects. We report two cases of distal femur osteosarcoma that had been undergone wide resection arthrodesis initially. Arthrodesis was converted to total knee arthroplasty with hinged prosthesis after many years. We describe patients' history and outline their surgical therapy and prognosis. To the best of the authors' knowledge, few cases have been previously reported in the literature.

Background: Acquiring knowledge about anatomic and geometric quantities of bones is among the most vitalparameters in orthopedic surgery that has a significant effect on the treatment of various disorders and subsequentoutcomes. The aim of this study was to obtain anthropometric information for distal femur in order to compare withsimilar dimensions of prosthesis used in total...
متن کاملRadiologic Assessment of Distal Femur Cutting Angle in Varus Knee Candidates for Total Knee Arthroplasty
Background: In a total knee arthroplasty surgery the goal is to produce 90 degree angle between the knee articular lobe and the mechanical femoral line. Most orthopedic surgeons usually utilize a 5 to 7 degree for distal femoral cutting angle. In this study we will aim at clearing this question, that whether the” five-seven degree” distal femoral cutting angle supposed to be an equable spectrum...

Background: The valgus cut angle (VCA) of the distal femur in Total Knee Arthroplasty (TKA) is measured preoperativelyon three-joint alignment radiographs. The anatomical axis of the femur can be described as the anatomical axis of thefull length of the femur or as the anatomical axis of the distal half of the femur, which may result in different anglesin some cases. During TKA, the anatomical ...

Background: Evaluating the landmarks for rotation of the distal femur is a challenge for orthopedic surgeons. Although the posterior femoral condyle axis is a good landmark for surgeons, the surgical transepicondylar axis may be a better option with the help of preoperative CT scanning. The purpose of this study was to ascertain relationships among the axes’ guiding distal femur rotational ...
