One strong constraint in ATLAS is the easy and fast access to the Tile calorimeter readout without any destructive interference with the rest of the detector. Therefore the drawer system has been designed to place all PMTs and associated electronics on a movable system inside the TILECAL girders which provide both, the structural support to the individual modules and the solenoid return ux. In ...

PURPOSE The purpose of this study was to objectively evaluate the anatomic and biomechanical outcomes of anterior cruciate ligament (ACL) reconstruction with transtibial versus anteromedial portal drilling of the femoral tunnel. METHODS Ten human cadaveric knees (5 matched pairs) without ligament injury or pre-existing arthritis underwent ACL reconstruction by either a transtibial or anterome...

BACKGROUND Tear of the anterior cruciate ligament (ACL) is a common ligamentous injury of the knee. Reconstruction of this ligament is often required to restore functional stability of the knee. Outcome of ACL reconstruction is significantly affected by how the graft is fixed to the bone. This study is to determine if there is a different clinical outcome after cortical versus cortical-cancello...

We aimed to summarize the effectiveness and changing trends of reconstruction for anterior cruciate ligament (ACL) posterior (PCL) injuries using all-inside arthroscope technique. Between May 2013 2019, 29 patients with ACL PCL ligaments rupture were included. All male, a mean age 25.2±2.9 years. The follow-up period was 2.4±0.7 years (Range, 2-4 years). Reconstruction surgery performed by auto...

BACKGROUND Previous studies have indicated that higher knee joint laxity may be indicative of an increased risk of anterior cruciate ligament (ACL) injuries. Despite the frequent clinical use of knee arthrometry in the evaluation of knee laxity, little data exist to correlate instrumented laxity measures and ACL strain during dynamic high-risk activities. Purpose/ HYPOTHESES The purpose of th...

BACKGROUND Anterior cruciate ligament (ACL) rupture is the biggest concern for orthopedic surgeons who are involved in sports injuries, so most of ACL reconstruction surgeries are sports related. ACL injuries in female athletes are 2 - 8 times more common than male athletes in similar sport injuries. OBJECTIVES The aim of this study was to compare knee laxity changes in the menstrual cycle in...

The anterior cruciate ligament (ACL) is an important structure that maintains the stability of knee joints. Animal models of ACL injury are helpful to explore its underlying mechanisms, and strategies for prevention, treatment and rehabilitation. Therefore, the aim of the present study was to develop an efficient model of ACL injury in cynomolgus monkeys via arthroscopic techniques. In the pres...

We conducted a retrospective, minimum 2-year follow-up study to evaluate the effectiveness of a single-incision endoscopic anterior cruciate ligament reconstruction technique using patellar tendon autograft without extraarticular augmentation and followed by accelerated rehabilitation. One hundred three patients were evaluated (mean followup, 36 months; range, 24 to 55). There were significant ...

Background Publication bias is a form of scientific misconduct. It threatens the validity of research results and the credibility of science. Although several tests on publication bias exist, no in-depth evaluations are available that examine which test performs best for different research settings. Methods Four tests on publication bias, Egger's test (FAT), p-uniform, the test of excess sign...
