Ligamentous structures of the knee are numerous and complex, including the anterior and posterior cruciate ligaments, medial and lateral collateral ligaments, ligaments of the posteromedial and posterolateral corners, and the anterolateral ligament. Clinical assessment after a knee injury is paramount and can direct both the clinician's choice of imaging study and the radiologist's interpretation. Imaging is crucial in that it provides additional information for diagnosis, management, and surgical planning...

PURPOSE: To investigate the appropriate mediolateral placement of symmetrical tibial components and the amount of overhang expected from the posterolateral of tibial components implanted to give ideal coverage and the subsequent incidence of residual knee pain and reduction in functional capacity. METHOD: A retrospective evaluation was made of 146 consecutive total knee arthroplasties. The posterolateral overhang, rotational alignment and coverage of the tibial component were measured on a post-operative CT scan and the effect of posterolateral overhang on clinical outcomes was analysed 3 years after surgery...

REVIEW
Thomas K Miller
Patients who present for anterior cruciate ligament (ACL) revision with a high-grade pivot shift at the time of an index ACL revision procedure and subsequent reconstruction failure or a high-grade pivot shift at revision surgery, patients with generalized joint laxity, and those requiring softs tissue grafts should be considered candidates for lateral tenodesis to supplement intraarticular graft revision. Although there is no consensus regarding the optimal lateral tenodesis technique, due to the tibial positioning associated with tensioning and fixation of extra-articular procedures, a lateral tenodesis should not be used in patients with posterolateral corner injuries or lateral compartment articular disease...

The number of posterolateral corner (PLC) injury patients has risen owing to the increased motor vehicle accidents and sports activities. Careful examination is required because this injury is easy to overlook and may lead to chronic instability. The purpose of this article is to review the anatomy, biomechanics, diagnosis, classification and, treatment of PLC injuries and summarize the recent literatures regarding the treatment outcomes.

Magnetic resonance imaging and a thorough understanding of its interpretation in the diagnosis and management of injuries to the ligaments about the knee is an essential skill for orthopedists. The goal of this review is to provide a description of the native and injured anatomy through magnetic resonance imaging and its correlations, when appropriate, as seen through the arthroscope at the time of surgery. The ligaments of focus include the anterior cruciate ligament, the posterior cruciate ligament, the medial collateral ligament, the posterolateral corner, the anterolateral ligament, and the medial patellofemoral ligament...

Acute posterolateral corner injuries of the knee with associated hamstring avulsions and peroneal paralysis are rare in rugby. Regain of motor function following a complete paralysis is documented to be 38%. To our knowledge, only one case describes return to preinjury level of competitive sport taking up to 27 months. A 24-year-old international level rugby player, a medical student, sustained an acute posterolateral knee injury with associated anterior cruciate ligament tear, bicep femoris and semimembranosus avulsions as well as a complete peroneal paralysis...

The posteromedial corner of the knee encompasses five medial structures posterior to the medial collateral ligament. With modern MRI systems, these structures are readily identified and can be appreciated in the context of multiligamentous knee injuries. It is recognized that anteromedial rotatory instability results from an injury that involves both the medial collateral ligament and the posterior oblique ligament. Like posterolateral corner injuries, untreated or concurrent posteromedial corner injuries resulting in rotatory instability place additional strain on anterior and posterior cruciate ligament reconstructions, which can ultimately contribute to graft failure and poor clinical outcomes...

BACKGROUND: We identified common morphologies of tibial plateau fractures that arise with multiligament knee injuries (MLKIs), and investigated the relationship of the fracture with ligament tears. We also evaluated the correlation of 3 tibial plateau fracture classification systems (Schatzker, AO, and Duparc). METHODS: Over a 2-year period, a single orthopaedic surgeon at our institution managed 90 MLKIs. Images of those knees with a tibial plateau fracture were retrospectively reviewed and classified per Schatzker, AO, and Duparc systems...

Posterolateral corner avulsion fractures are a rare variant of ligamentous knee injury primarily described in the skeletally immature population. Injury is often related to a direct varus moment placed on the knee during sporting activities. Various treatment strategies have been discussed ranging from nonoperative management, to excision of the bony fragment, to primary repair with screws or suture. The described technique is a means for achieving fixation of the bony avulsion using principles familiar to double-row transosseous equivalent rotator cuff repair...

Injury to the posterolateral corner of the knee is a difficult condition to treat. We know a lot about the anatomy and different methods with which we can reconstruct this complex area of the knee. Despite these advances, injuries to this area still do not lead to great surgical outcomes.

Reverse Segond fracture is an uncommon avulsion fracture of the tibial attachment of the deep portion of the medial collateral ligament of the knee. We report a reverse Segond fracture associated with anterior cruciate ligament tibial avulsion fracture and anteromedial tibial rim fracture. Unlike previous reports, the combination of reverse Segond fracture, anteromedial tibial rim fracture, and anterior cruciate ligament avulsion fracture was not associated with posterior cruciate ligament injury, posterolateral corner injury, or tibial plateau fracture...

Musculoskeletal trauma and infections are commonly encountered in the emergency department. Magnetic resonance imaging (MRI) is rarely employed in true emergencies and most musculoskeletal studies can be deferred to the outpatient setting. This article seeks to address the urgent conditions in which MRI can play a role in diagnosis, management, and treatment. This article outlines MRI's role in the evaluation of posterolateral corner injuries and other soft-tissue pathologies such as rhabdomyolysis, diabetic myonecrosis, septic arthritis, cellulitis, necrotizing fasciitis, and compartment syndrome...
