OBJECTIVE Evaluate the correlation between magnetic resonance imaging, clinical examination and intraoperative identification of posterolateral corner injuries of the knee. METHODS We compared the findings of physical examination under anesthesia and intraoperative findings as the gold standard for the posterolateral corner injury with the reports of the MRIs of patients who underwent reconst...

Posterolateral corner injuries represent a complex injury pattern, with damage to important coronal and rotatory stabilizers of the knee. These lesions commonly occur in association with other ligament injuries, making decisions regarding treatment challenging. Grade III posterolateral corner injuries result in significant instability and have poor outcomes when treated nonoperatively. As a res...

INTRODUCTION Autogenous iliac crest bone graft continues to be the material of choice for posterolateral lumbar intertransverse process spine fusion. However, continued interest lies in developing bone graft alternatives that can be used as either graft extenders, graft enhancers, or graft substitutes. It was the purpose of this study to evaluate the efficacy of a demineralized bone matrix/ hya...

BACKGROUND There is controversy regarding the necessity of reconstructing both the posterolateral and anteromedial bundles of the anterior cruciate ligament. HYPOTHESIS A laterally oriented transtibial drilled femoral tunnel replaces portions of the femoral footprints of the anteromedial and posterolateral bundles of the anterior cruciate ligament. STUDY DESIGN Descriptive laboratory study....

An anatomical study was conducted to gain orientation regarding the posterolateral approaches. The asterion is defined as the junction of the lambdoid, parietomastoid, and occipitomastoid sutures. This anatomical point has been widely used as a landmark in lateral approaches to posterior fossa. Although there are many common practices in posterolateral approaches, studies providing accurate ana...

SYNOPSIS Injuries to the posterolateral corner of the knee pose a significant challenge to sports medicine team members due to their complex nature. Identifying posterolateral corner injuries is paramount to determining proper surgical management of the injured athlete, with the goal of preventing chronic pain, instability, and/or surgical failure. Postoperative rehabilitation is based on the s...

Posterolateral rotatory instability is a relatively uncommon cause of unstable total knee arthroplasty (TKA). In most cases, surgical treatment requires revision TKA into a more constrained design or thicker polyethylene liner. We present a case of a patient with unstable TKA who remained unstable after increasing thickness of the polyethylene liner and undergoing more constrained TKA. After se...

Posterolateral instability (PLI) is common with posterior cruciate ligament tears and is less common with anterior cruciate ligament tears, and isolated PLI is rare. There are varying degrees of PLI with respect to pathologic external tibial rotation, and varus laxity. Surgical treatment of PLI must address all components of the PLI (popliteus tendon, popliteofibular ligament, lateral collatera...

Although injuries to the posterolateral corner of the knee were previously considered to be a rare condition, they have been shown to be present in almost 16% of all knee injuries and are responsible for sustained instability and failure of concomitant reconstructions if not properly recognized. Although also once considered to be the "dark side of the knee", increased knowledge of the posterol...
