Surgical treatment for injuries to soft connective tissues are estimated at about 800,000 cases each year in the US. For these surgical procedures, interference screws or suture anchors are needed. Currently, materials used for the devices are non-degradable metals or bioresorbable polymers. However, these materials do lead to complications. Metallic materials suffer from difficulties encounter...

BACKGROUND Primary stability of the graft is essential in anterior cruciate ligament surgery. An optimal method of fixation should be easy to insert and provide great resistance against pull-out forces.A controlled laboratory study was designed to test the primary stability of ACL tendinous grafts in the tibial tunnel. The correlation between resistance to traction forces and the cross-section ...

An anterior cruciate ligament (ACL) tear is one of the most common orthopaedic injuries. Optimal results are not always achieved after surgical reconstruction after a surgical technical error, namely, tunnel malposition. Understanding of the anatomy is vital, and several anatomic landmarks can be used to aid in an optimal reconstruction technique. The purpose of this Technical Note is to descri...

Abstract Background Interference screw is commonly used for graft fixation in anterior cruciate ligament (ACL) reconstruction. However, previous studies had reported that the insertion of interference screws significantly caused laceration. The purposes this study were to (1) quantitatively evaluate laceration from one single PEEK screws; and (2) determine whether different types sutures reduce...

Bone tunnel enlargement following anterior cruciate ligament (ACL) reconstruction can complicate revision surgery. This study compared postoperative tibial tunnel widening in patients who underwent arthroscopically assisted, single-incision, four-strand hamstring ACL reconstruction using a poly-L-lactic acid/hydroxyapatite blend (PLLA+HA) bioabsorbable interference screw for tibial fixation, wi...

INTRODUCTION Anterior Cruciate Ligament (ACL) is as one of the most frequently injured ligaments in the modern contact sports scenario. Graft fixations can be achieved during anterior cruciate ligament (ACL) reconstructions by using either bioabsorbable screws or metal screws. The objective of this study was to compare the functional outcomes after bioabsorbable and metallic interference screw ...

Background: The short-time creep behavior for a series of biodegradable nanocomposites which is used as implantable device into body is a crucial factor. In the current paper, we aimed to study the effect of bioactive glass nanoparticles (BGn) on creep and creep-recovery behaviors of PLA/PCL blends at different given load and different applied temperatures. Method: A series of biodegradab...

Treatment of the torn ACL is of great interest in the human sports medicine world. Over 400,000 patients are estimated to get an ACL tear each year in the US. ACL injuries in humans are of great interest not only because of their large numbers, but also because of the significant disability that accompanies these injuries – the short term disability of pain and loss of knee function, and the lo...

Recent anatomical and biomechanical studies on the anterolateral ligament (ALL) of the knee have shown that this structure has an important function in relation to joint stability, especially when associated with anterior cruciate ligament (ACL) injury. However, the criteria for its reconstruction have not yet been fully established and the surgical techniques that have been described present v...

The quadriceps tendon autograft can be used for primary and revision anterior cruciate ligament (ACL) reconstruction. Despite several successful clinical reports, graft fixation issues remain, and the ideal technique for fixation continues to be controversial. We present a technique of ACL reconstruction with quadriceps tendon autograft (QTA) using a patellar bone block. The tendon end is fixed...
