Rotational alignment of femoral component for minimal medial collateral ligament release in total knee arthroplasty.

Purpose: We attempted to determine the degree of rotation of the femoral component to achieve an ideal rectangular flexion gap with minimal medial collateral ligament (MCL) release using a modified measured technique.

Materials And Methods: Group I consisted of 60 osteoarthritis patients (72 cases) who underwent total knee arthroplasty (TKA) with minimal MCL release and Group II consisted of 48 patients without osteoarthritis (61 cases). We performed computed tomography (CT) scanning of the knee with 90 degree flexion in all of the patients and analyzed the angles between the distal femur landmarks and the tibial mechanical axis using a Picture Archiving Communication system.

Rapidly Progressive Cardiac Manifestation of Behçet's Disease Involving Conduction System and Aortic Valve.

Cardiac conduction system impairment is a rare clinical manifestation of Behçet's disease. We report a patient who showed 1st degree atrioventricular block at first presentation, and showed aggravated finding of 3rd degree atrioventricular block on five months later. His cardiac manifestation finally developed to acute severe aortic regurgitation on six months later from his first cardiac manifestation.

A serial ultrasound assessment of neoaneurysm following paclitaxel-eluting stent implantation.

We present a case of serial regression of aneurysm of coronary artery complicating paclitaxel-eluting Taxus stent implantation in the mid anterior descending artery evaluated by intravascular ultrasound in a 55-year-old woman.
