Simulation of Ti-6Al-4V cruciform welded joints subjected to fatigue load using XFEM

Journal of Mechanical Engineering and Sciences, 2019
The stress distribution of cruciform shape welded joints is analyzed by finite element codes ABAQUS. Welded joints with various weld shapes and sizes are investigated to estimate the fatigue life of different joints.

Arthroscopic Repair of Posterior Root Tear of the Lateral Meniscus Using the Anterior Meniscofemoral Ligament

Arthroscopy Techniques, EarlyView.
Abstract Posterolateral meniscus root tears are frequently associated with anterior cruciate ligament injuries and contribute to altered knee biomechanics, increased joint loading, and potential graft failure. Despite various described repair techniques, the use of the anterior meniscofemoral ligament (aMFL, ligament of Humphrey) for repair is not ...

Less‐Invasive Capsulotomy Strategy in Hip Arthroscopy: The Gluteus Minimus Sign as a Visual Landmark for the Joint Capsule Based on Cadaveric Analysis

Arthroscopy Techniques, EarlyView.
Abstract Hip arthroscopy requires a capsulotomy to achieve adequate visualization and access; however, an excessive incision can increase the risk of postoperative instability. This technical note describes a less‐invasive capsulotomy technique guided by the “gluteus minimus sign,” a fibrous membrane connecting the main tendon of the gluteus minimus to
