Risk of Anterior Femoral Notching in Navigated Total Knee Arthroplasty
BACKGROUND We retrospectively investigated the prevalence of femoral anterior notching and risk factors after total knee arthroplasty (TKA) using an image-free navigation system. METHODS We retrospectively reviewed 148 consecutive TKAs in 130 patients beginning in July 2005. Seventy knees (62 patients) underwent conventional TKA, and 78 knees (68 patients) received navigated TKA. We investiga...
متن کاملBiomechanical Consequences of Anterior Femoral Notching in Cruciate-Retaining Versus Posterior-Stabilized Total Knee Arthroplasty.
Anterior femoral notching during total knee arthroplasty is a potential risk factor for periprosthetic supracondylar femur fracture. We conducted a study to determine if the design of the femoral implant changes the risk for periprosthetic supracondylar femur fractures after anterior cortical notching. An anterior cortical defect was created in 12 femoral polyurethane models. Six femora were in...
متن کاملFemur 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...
متن کاملAging Effect on Femoral Stress Fracture Risk after Computer-navigated Total Knee Arthroplasty
INTRODUCTION Recent clinical studies have shown that computer navigation for total knee arthroplasty (TKA) provides improved component alignment accuracy, and can help to avoid femoral malrotation and errors in axial alignment [1]. However, femoral stress fracture after computernavigated TKA has been reported due to the pin hole [2] and we hypothesized that osteoporosis would be one of the key ...
متن کاملThe Effect of Sagittal Femoral Bowing on the Femoral Component Position in Total Knee Arthroplasty
Background: In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment ofthe femoral component in total knee arthroplasty (TKA).Methods: There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittalfemoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cor...
