Comparing supine CT scanogram and standing long-leg radiograph for postoperative alignment in total knee arthroplasty: a prospective study.

Purpose: Achieving precise postoperative alignment is critical for the long-term success of total knee arthroplasty (TKA). Long-leg standing radiograph (LLR) at 6 weeks post-op is the gold standard for assessing alignment, but its reliance on weight-bearing and positioning makes it less practical in the early postoperative period. Supine computed tomography scanogram (CTS) offers a potential alternative.

Assessing the current role of AP and Bernageau view radiographs in measurement of glenoid bone loss in patients with recurrent shoulder dislocation: correlation with computed tomography, magnetic resonance imaging, and arthroscopy.

Background: Evaluation of glenoid bone loss following recurrent anterior shoulder dislocations is normally performed using cross sectional imaging.

Objectives: To assess how anteroposterior (AP) and Bernageau view radiographs compare to computed tomography (CT), magnetic resonance imaging (MRI) and arthroscopy for evaluating glenoid bone loss in patients with recurrent anterior shoulder dislocation.

Materials And Methods: A prospective observational study was performed on 32 patients over two years at a tertiary orthopedic center.

True all inside meniscus repair using the popliteus tendon.

The popliteus tendon is a useful anchor point to repair the posterior horn of the lateral meniscus. We describe a new, economical technique that does not violate the neurovascular structures, using an antegrade suture passer and a 2-0 fiberwire to repair the posterior segment including posterior horn of the lateral meniscus taking bites through the capsule and meniscus or the popliteus tendon and meniscus with no anchors in the capsule or popliteus. 9 patients were operated upon using this technique and the mean IKDC score improved from 24.

Ultrasound guided arthroscopic meniscus surgery.

Ultrasound is a useful adjunctive intra-operative imaging modality for soft tissue pathologies. It is readily available in the operating theater and has the distinct advantage of being more portable than an MRI, with no harmful radiation. It is especially useful for determining if any extra articular cysts have been decompressed through arthroscopic surgery, if a parameniscal cyst has been removed completely or if extrusion has been reduced adequately in a meniscus root repair.

How Important is the Tunnel Position in Outcomes Post-ACL Reconstruction: A 3D CT-Based Study.

Background: Drilling the femoral and tibial tunnels at their anatomical locations are critical for good outcomes and involve seeing the footprints well. We intended to compare two techniques of drilling the tunnels and the patient-reported outcomes and knee stability of patients undergoing single bundle ACL reconstruction using 3D CT to evaluate if the tunnels were anatomical or not.

Materials And Methods: Sixty single bundle ACL reconstructions were analyzed, 30 each with Technique A and B.

Does Viewing the ACL Femoral Footprint End on Using a High Medial Portal Produce Better Tunnel Placement as Compared to Viewing it from a Lateral Portal while Drilling: A 3D CT-based Pilot Study.

Background: Anatomical placement of an ACL graft is critical to the clinical outcome of an ACL reconstruction. The purpose of the study was to compare the conventional technique of drilling a femoral tunnel from a medial portal while viewing it from a lateral portal versus viewing it from a high anteromedial portal and drilling it from a low medial portal. We hypothesized that the high anteromedial portal possibly provides an end-on view of the tunnel and would lead to a more favourable tunnel position.

Implantless Fixation of a Large Osteocartilaginous Fracture of the Lateral Femoral Condyle in a Child.

We describe for the first time a case of lateral femoral condyle fracture following a fall in a 13-year-old child that was reduced arthroscopically using a probe. It was definitively fixed with 0 vicryl sutures in a cruciate pattern after being initially stabilised with 1.5-mm Kirschner wires.

Anterior tibial plateau fracture: An often missed injury.

Background: In most classifications of tibial plateau fractures, including one used most widely-Schatzker classification, fractures are described as a combination of medial and lateral condyle, primarily in the sagittal plane. Coronal component of these fractures, affecting the posterior tibial condyle is now well recognized. What is not described is anterior coronal component of the fracture, what we are calling "anterior tibial condyle fracture".

Recognition and analysis of protein-coding genes in severe acute respiratory syndrome associated coronavirus.

Motivation: The recent outbreak of severe acute respiratory syndrome (SARS) caused by SARS coronavirus (SARS-CoV) has necessitated an in-depth molecular understanding of the virus to identify new drug targets. The availability of complete genome sequence of several strains of SARS virus provides the possibility of identification of protein-coding genes and defining their functions. Computational approach to identify protein-coding genes and their putative functions will help in designing experimental protocols.
