OBJECTIVE Knee ligament injuries frequently cause devastating impairment to the injured. In car-pedestrian impact accidents, lateral-medial shear displacement is one of principal mechanisms of knee ligament injuries. The current study aims to investigate injury thresholds of knee ligaments under lateral-medial shear loading to improve pedestrian safety. METHODS Ten isolated human knee joints ...

To cite: Chahla J, von Bormann R, Engebretsen L, et al. JISAKOS 2016;1:292– 302. ABSTRACT The posterior cruciate ligament (PCL) is recognised to be the main posterior stabiliser of the knee. PCL injuries are most commonly associated with concurrent ligament injuries and also with a high prevalence of chondral and meniscal injuries. Recent evidence of the accuracy of the stress radiographs as an...

The purpose of this study was to examine the injury incidence and pattern of injuries in youth female and male team handball players using two different prospective registration methods; match reports (90 teams, 1080 players) and coach reports (34 teams, 428 players). A total of 118 injuries were recorded by the coach report, of which 93 (79%) were acute injuries (incidence training: 0.9+/-0.16...

OBJECTIVE Anterior cruciate ligament (ACL) injuries are the most common ligament injury in the United States. These injuries can be career ending for athletes and severely disabling for all individuals. Our objectives are to review the epidemiology of these injuries, as well as ACL biomechanics, anatomy, and nonsurgical and surgical management so that generalists as well as sports medicine phys...

Background/aim Poor frontal plane knee control can manifest as increased dynamic knee valgus during athletic tasks. The purpose of this study was to investigate the association between frontal plane knee control and the risk of acute lower extremity injuries. In addition, we wanted to study if the single-leg squat (SLS) test can be used as a screening tool to identify athletes with an increased...

We retrospectively reviewed the hospital records of 68 patients who had been referred with an injury to the posterolateral corner of the knee to a specialist knee surgeon between 2005 and 2009. These injuries were diagnosed based on a combination of clinical testing and imaging and arthroscopy when available. In all, 51 patients (75%) presented within 24 hours of their injury with a mean presen...

BACKGROUND Biomechanical studies have reported that the posterior cruciate ligament (PCL) functions as a restraint against excessive tibial internal rotation at higher degrees of knee flexion. PURPOSE To investigate the use of a supine internal rotation (IR) test for the diagnosis of grade III PCL injuries. The hypothesis was that internal rotation would be greater in patients with grade III ...

Previous study has shown a likely link between increased shoe- surface traction and risk of knee Anterior Cruciate Ligament (ACL) injury. Portable natural grass systems are being used more often in sport, but no study to date has investigated their relative safety. By their nature, they must have high resistance to falling apart and therefore newly laid systems may be at risk of creating excess...

Multiligamentous knee injuries with simultaneous patellar tendon ruptures are rare. Surgeons must be prepared to address injured structures of the knee to allow return of knee function. Restoring motion while protecting repairs is important. The authors present 2 cases and discuss treatment strategy for preoperative evaluation, surgical intervention, and postoperative care.
