BACKGROUND The risk of anterior cruciate ligament (ACL) injury is 2 to 10 times greater in women than men. While the effect of sex on injury risk is well established, its effects on surgical outcomes remain controversial. PURPOSE/HYPOTHESIS To investigate whether the biomechanical outcomes of ACL reconstruction are affected by sex using an established porcine model that displays similar sex-s...

The use of allograft bone is becoming increasingly common. intrinsic mechanical and structural properties the graft are major importance for osseointegration. Current cleaning treatments using chemical or physical products increase biosafety but may disturb these characteristics. A new treatment cancellous cortical by simple washing (sonication centrifugation) supercritical carbon dioxide (scCO...

Biomechanical comparison between rigid and non-rigid posterior stabilization systems following lumbar interbody fusion has been conducted in several studies. However, most of these previous studies mainly focused on investigating biomechanics adjacent spinal segments or spine stability. The objective the present study was to compare biomechanical responses devices when using different instrumen...

BACKGROUND Ligament reconstruction is a common procedure in orthopedic surgery. Although several popular techniques are currently in use, new methods are proposed for secure fixation of the tendon graft into the bone tunnel. PURPOSES We sought to introduce our new technique of Bashti bone plug for fixation of soft tissue graft in anterior cruciate ligament (ACL) reconstruction and to compare ...

Posterior cruciate ligament (PCL) injuries usually constitute part of a multiligament injury. Isolated PCL injuries account for only approximately 3% of all ligament injuries. No consensus on optimal surgical reconstruction exists. The PCL is a double-bundle structure that functions in an anisometric manner. Biomechanical studies have shown that re-creating the PCL femoral double-bundle configu...

Methods of reconstruction of the anterior cruciate ligament (ACL) have developed considerably over the last 15 years. Primary repair and extra-articular procedures have failed to reproduce satisfactory stability of the knee 1 and the use of prosthetic ligam...

STUDY DESIGN Comparative evaluation of in vitro and in vivo biomechanics, resulting fusion and histomorphometric aspects of polyetheretherketone (PEEK) versus titanium (Ti) interbody fusion devices in an animal model with similar volumes of bone graft. OBJECTIVE Identify differences in the characteristics of fusion and biomechanics immediately following implantation (time 0) and at 26 weeks w...

The management of irreparable rotator cuff tears remains challenging. Since its introduction by Mihata in 2012, superiorcapsule reconstruction (SCR) has grown in popularity at an astonishingly rapid rate. The aim of this article is to providea comprehensive review of the available literature, in order to highlight what has so far been published on SCR,covering all aspects including biomechanica...
