Rupture of the patellar tendon is an uncommon injury that requires acute surgical repair to restore the function of the knee. Multiple techniques for repair have been described in the literature. Complications with these repair techniques include rerupture and extensor lag caused by gap formation at the site of repair. Thus, many surgeons have suggested augmenting the standard repair. Several methods of augmentation have been described each with disadvantages. The purpose of this article was to present our case series of six patients with acute patella tendon ruptures treated by a novel procedure using strong sutures...

Here we demonstrate our surgical procedure of minimally invasive aortic valve replacement through right anterolateral mini-thoracotomy. Preoperative evaluation of the whole aorta by contrast-enhanced computed tomography scan is important to prevent cerebrovascular complications. The patient is set in a mild left lateral decubitus position. A skin incision is made along the anterior axillary line to the inframammary fold and the chest is opened at the 3rd or 4th intercostal space. Cardiopulmonary bypass is usually established by femoro-femoral bypass...

For patients with keratoconus, rigid gas-permeable contact lenses are the first line correction method and allow good visual acuity for quite some time. In severe stages of the disease with major cone-shaped protrusion of the cornea, even specially designed keratoconus contact lenses are no longer tolerated. If there are contraindications for intrastromal ring segments, corneal transplantation typically has a very good prognosis. In patients with advanced keratoconus - especially after corneal hydrops due to rupture of Descemet's membrane - penetrating keratoplasty (PKP) is still the first line surgical method...

BACKGROUND: Double-gloving is endorsed by a number of healthcare authorities worldwide, on the basis that it promotes patient and surgeon safety; adoption of this practice amongst surgeons remains limited, based upon anecdotal reporting that double-gloving may compromise surgical technique due to impaired dexterity and sensation. The aim of this study is to formally investigate and demonstrate the effect of double-gloving upon the quality of knot tying, an essential surgical skill. METHODS: An international cohort of practising general surgeons hand tied surgical knots, under both single-gloved and double-gloved conditions, using monofilament and braided sutures, at two different gauges...

BACKGROUND AND OBJECTIVES: Therapeutic laparoscopy was incorporated into surgical practice more than 25 y ago. Several modifications have since been developed to further minimize surgical trauma and improve results. Minilaparoscopy, performed with 2- to 3-mm instruments was introduced in the mid 1990s but failed to attain mainstream use, mostly because of the limitations of the early devices. Buoyed by a renewed interest, new generations of mini instruments are being developed with improved functionality and durability...
