conversion of fused knee following distal femur tumor surgery to total knee arthroplasty

Conversion of Fused Knee Following Distal Femur Tumor Surgery to Total Knee Arthroplasty

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 ...

Radiologic 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...

Anthropometric Measurements of Distal Femur to Design the Femoral Component of Total Knee Arthroplasty for the Iranian Population

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...

Total knee arthroplasty after previous knee surgery

Femur positioning in navigated total knee arthroplasty.

Navigated total knee arthroplasty (TKA) results in better restoration of neutral mechanical axis than does the conventional technique. Nevertheless, coronal malalignment has not been eliminated. It is yet unknown whether errors in implant positioning occur more on the femoral side, more on the tibial side, or equally on both sides. The hypothesis of this study was that a predominance of coronal...

Infection Following Total Knee Arthroplasty

For most orthopedists, total knee arthroplasty (TKA) has been regarded as the most effective surgery for patients with severe knee diseases. Though seldom occur, postoperative infection certainly remains one of the most devastating and dreaded complications of TKA. Thus, careful and early diagnosis is needed. After diagnosis, categorize the infection type and choose a rightful and sequential st...
