Authors: Jorge Chahla, M.D., Ph.D., Editorial Board, Brady T. Williams, M.D., and Robert F. LaPrade, M.D., Ph.D. Abstract: Historically described as the “dark side of the knee,” the posterolateral corner of the knee has been a significant focus [...]
Clinical Presentation and Outcomes Associated With Fabellectomy in the Setting of Fabella Syndrome
Background Clinical outcomes pertaining to isolated lateral fabellectomy in the setting of fabella syndrome are limited to small case reports at this time. Purpose To assess the most common presenting symptoms, clinical outcomes, and satisfaction after fabella excision [...]
Posterolateral corner of the knee: an expert consensus statement on diagnosis, classification, treatment, and rehabilitation
2018 Knee Surgery, Sports Traumatology, Arthroscopy The posterolateral corner (PLC) was once considered the “dark side” of the knee, and it was not until recent times that consistent anatomic and biomechanical descriptions aided in improved outcomes. Several factors [...]
The Influence of Graft Tensioning Sequence on Tibiofemoral Orientation During Bicruciate and Posterolateral Corner Knee Ligament Reconstruction
2018 AJSM Background: During multiple knee ligament reconstructions, the graft tensioning order may influence the final tibiofemoral orientation and corresponding knee kinematics. Nonanatomic tibiofemoral orientation may result in residual knee instability, altered joint loading, and an increased propensity [...]
Anatomic Posterolateral Corner Reconstruction
Arthroscopy Techniques 2016 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 [...]
Improving Outcomes for Posterolateral Knee Injuries
JOURNAL OF ORTHOPAEDIC RESEARCH MONTH 2014 The posterolateral corner of the knee was noted for both its complex anatomy and diagnostic challenges. This study breaks down the understanidng of the posterolateral knee into five primary areas: surgical approach and relevant [...]
Outcomes of Untreated Posterolateral Knee Injuries: an In Vivo Canine Model
KSSTA 2011 The purpose of our study was to determine if sectioning the canine fibular collateral ligament, popliteus tendon, and popliteofibular ligament would result in residual posterolateral instability and produce measureable evidence of early-onset arthritis on ultra-high field MRI. Download Full [...]
Avoiding Tunnel Collisions Between Fibular Collateral Ligament and ACL Posterolateral Bundle Reconstruction
KSSTA 2011 Purpose: The purpose of this study was to evaluate the risk of tunnel collisions of the fibular collateral ligament (FCL) and posterolateral bundle anterior cruciate ligament(PLB-ACL) tunnels during a combined FCL and doubledundle (DB) ACL reconstruction. Methods: Thirty-six 4th-generation [...]
Outcomes of Treatment of Acute Grade-III Isolated and Combined Posterolateral Knee Injuries
JOURNAL OF BONE AND JOINT SURGERY 2011 Few studies have reported the outcomes of surgical treatment of an acute grade-III posterolateral knee injury. Our purpose was to report the objective stability and subjective outcomes for a prospective series of patients [...]
Analysis of the Static Function of the Popliteus Tendon and Evaluation of an Anatomic Reconstruction
AJSM 2010 The popliteus tendon has important dynamic and static stabilizing functions at the knee. Evaluation of its static role as the ‘‘fifth ligament’’ of the knee and a subsequent analysis of a popliteus tendon reconstruction has not been performed. [...]
Outcomes of an Anatomic Posterolateral Knee Reconstruction
JOURNAL OF BONE AND JOINT SURGERY 2010 Chronic posterolateral knee injuries often result in substantial patient morbidity and functional instability. The clinical stability and functional outcomes following anatomic reconstructions in patients with a chronic posterolateral knee injury have not been [...]
The Role of the Oblique Popliteal Ligament and Other Structures in Preventing Knee Hyperextension
AJSM 2010 Ligament restraints to terminal knee extension are poorly understood. This study hypothesized (1) as with other motions of the knee, genu recurvatum is limited primarily by a named, identifiable structure, and (2) as the largest static structure of the posterior [...]
Snapping biceps Femoris Tendon Treated with an Anatomic Repair
KSSTA 2009 Three patients were seen for pain and snapping over the lateral aspect of their symptomatic knee during deep knee flexion. On physical examination, each patient had subluxation of the long head of the biceps over the lateral aspect of [...]
A Comparative Analysis of 7.0-Tesla Magnetic Resonance Imaging and Histology Measurements of Knee Articular Cartilage in a Canine Posterolateral Knee Injury Model
AJSM 2009 There has recently been increased interest in the use of 7.0-T magnetic resonance imaging for evaluating articular cartilage degeneration and quantifying the progression of osteoarthritis. Download Full Article
Radiographic Identification of the Primary Posterolateral Knee Structures
AJSM 2009 It is often difficult to identify the attachment sites of the fibular collateral ligament, popliteus tendon, and popliteofibular ligament for chronic posterolateral knee injuries or during revision surgeries. Descriptions of radiographic landmarks for these attachment sites would assist [...]
The Reproducibility and Repeatability of Varus Stress Radiographs in the Assessment of Isolated Fibular Collateral Ligament and Grade-III Posterolateral Knee Injuries
JOURNAL OF BONE AND JOINT SURGERY 2008 Objective measures to quantitate the amount of lateral compartment opening for patients with lateral and posterolateral knee injuries have not been well documented. The purpose of the present study was to measure lateral [...]
Assessment of a Goat Model of Posterolateral Knee Instability
JOURNAL OF ORTHOPAEDIC RESEARCH 2008 The development of an in vivo animal model of posterolateral knee instability is desired for devising effective interventions for this injury. Sequential sectioning of the popliteus tendon, lateral collateral ligament, and lateral capsule was done [...]
