Location of the Anatomic Footprint Centers of the Anterior Cruciate Ligament Determined by Quadrant Method on Three-Dimensional Magnetic Resonance Imaging.

Background: The quadrant method is widely used to determine the femoral footprint center (FFC) on radiographs or computed tomography (CT) and can also describe the tibial footprint center (TFC). However, its application on three-dimensional (3D) magnetic resonance imaging (MRI) has been limited. This study aims to describe the ACL footprint center position on 3D MRI of healthy knees using the quadrant method.

Accuracy of total knee arthroplasty using hospital-based 3D printed patient-specific instrumentation: A radiology research.

Background: Patient-specific instruments (PSIs) were reported to improve implant position and rotation accuracy in total knee arthroplasty (TKA), among other benefits. Most PSIs used in TKA were commercial products from implant manufacturers, which could be time-consuming and could potentially affect accuracy as they relied on engineer's decision. This study aimed to present the radiological outcomes of PSI produced by the 3D printing facility at our hospital, with direct involvement of the surgeon in its design.

Novel technique for scapulothoracic arthroscopy: A case report of the application of intraoperative 3D imaging.

Introduction: Snapping shoulder syndrome could be effectively treated with scapulothoracic arthroscopy. The excision of the scapular superomedial corner is assumed to help lower the recurrence rate. However, the amount of resection is still controversial.

The Anatomical Numerical Measurement of Posterior Cruciate Ligament: A Vietnamese Cadaveric Study.

Background: The posterior cruciate ligament (PCL) is crucial to restrain the posterior translation of the tibia. Its anatomical structure is complex. A proper understanding of PCL anatomy may assist surgeon in reconstructing anatomically native PCL.
