Incorrect bone tunnel position, particularly on the femoral side, is a frequent cause of failed anterior cruciate ligament reconstruction. Several studies have reported that drilling the femoral tunnel through the anteromedial portal allows a more anatomical placement on the lateral femoral condyle and higher knee stability than does transtibial reconstruction.In the current study, the femoral ...

OBJECTIVE The objective of this study was to describe the MR imaging features of osteochondritis dissecans of the femoral sulcus, which have not been described previously. CONCLUSION Osteochondritis dissecans of the femoral sulcus has been recognized as a unique clinical and radiographic entity, warranting early diagnosis and appropriate treatment. Although this type of osteochondritis dissec...

Femoral shaft fractures are correlated with frequent morbidity and mortality. It is a major musculoskeletal disorder caused by tremendous force applied to the femur. One of most common surgical treatments for fixation intramedullary nailing (IM), which utilises specially designed metal rod screws be implanted into medullary canal. However, severe bowing femur can result in mismatch between IM n...

PURPOSE The object of this study was to evaluate entrance angle effects on femoral tunnel length and cartilage damage during anteromedial portal drilling using three-dimensional computer simulation. MATERIALS AND METHODS Data was obtained from an anatomic study performed using 16 cadaveric knees. The anterior cruciate ligament femoral insertion was dissected and the knees were scanned by comp...

The Multicenter ACL (anterior cruciate ligament) Revision Study (MARS) group was developed to investigate revision ACL reconstruction outcomes. An important part of this is obtaining and reviewing radiographic studies. The goal for this radiographic analysis is to establish radiographic findings for a large revision ACL cohort to allow comparison with future studies. The study was designed as a...

PURPOSE Three-dimensional (3D) effects of the single plane osteotomies of the proximal femur are compared and analyzed by the trigonometric method. MATERIALS AND METHODS The shape of proximal femur was simplified as a bent line. The bent line is the continuation of the three points-the center of the femoral head, the center of femoral neck at the base, and the center of the femoral shaft. The...

Advances in imaging technology and computer-assisted design (CAD) have recently enabled the introduction of patient-specific knee implant designs that hold the potential to improve functional performance on the basis of patient-specific geometries, namely a patient-specific sagittal and coronal curvature, as well as enhanced bone preservation. The objective of this study was to investigate the ...

We adopted a new computed tomography (CT)-free navigation system and noticed that, compared with our previous experience using a different type of CT-free navigation system that led to oversized and extended femoral component implanted compared with the conventional implantation, the femoral components were similarly implanted to the conventional method. The purpose of our study was to compare ...
