Backgroud: Anterior cruciate ligament reconstruction (ACLR) remains the gold standard treatment for anterior cruciate ligament (ACL) injury. However, a good functional outcome even after a successful surgery depends on multiple factors. It has been observed that certain patients with a chronic ACL injury demonstrate knee instability voluntarily. The authors observed that these patients might not perform well even after a successful surgery. This study aims to assess the outcome after ACL and other ligament reconstruction in patients with voluntary knee instability...

BACKGROUND: Posterolateral tibial plateau fractures (PTPF) remain a challenge for orthopedics surgeons because the special anatomical structures of the posterolateral corner of knee joint including the fibular head, the lateral collateral ligament, and the peroneal nerve, which impedes the exposure of the fracture fragments and need irregular implants to get a stable fixation. The purpose of present study was to introduce a new articular fracture fragments restoration technique for three patterns of PTPF and investigate the relationship between associated soft injuries and fracture patterns...

Injuries to the lateral collateral ligament (LCL) most commonly occur with concomitant cruciate ligament tears. Over the past decade, there has been increased interest in anatomic reconstruction of the posterolateral corner (PLC). Not much attention has been paid to anatomic primary LCL repair given the historically high failure rates of primary repair of lateral sided knee ligaments, but better outcomes can now be expected because of recent developments in additional suture augmentation. The purpose of this Technical Note is to describe the surgical technique of primary distal LCL repair using suture augmentation...

BACKGROUND: The fibular collateral ligament is a permanent and extracapsular ligament of the knee joint. It is located on the lateral aspect of the knee and extends from the lateral epicondyle of the femur to the lateral surface of the head of the fibula. As one of the main knee joint ligaments it is a stabilizer of the posterolateral corner of the knee and resists varus stress. The case report displays the bifurcated variant of the fibular collateral ligament. The aim of this study is to determine which of those bands should be considered dominant...

Knee dislocations leading to multiligament knee injuries are associated with a wide variety of bony, ligamentous, soft tissue, and neurovascular injury patterns. Numerous management strategies have been proposed including nonoperative treatment and surgical repair or reconstruction. In recent years, an emphasis has been placed on anatomic repair and reconstruction principles, which have shown superior outcomes compared with older techniques. However, despite these advances, clinical outcomes continue to vary widely, with many patients experiencing chronic pain, stiffness, loss of range of motion, instability, and failure to return to work or sports...

A knee dislocation that involves at least 2 of the 4 major ligament groups-such as the anterior cruciate ligament, the posterior cruciate ligament, or the posterolateral corner-is a catastrophic event for an athlete or trauma patient. Careful evaluation of these patients is needed to avoid disastrous outcomes. Surgeons must be cognizant of a number of key treatment concerns-such as tunnel crowding, controversies over graft fixation methods, and sparsity of level I clinical data-to make proper ligament repair decisions...

BACKGROUND: This is an experimental study conducted to assess whether the fibular head is a reliable reference point to identify the position of the common peroneal nerve at the posterolateral corner of the knee. MATERIALS AND METHODS: Twelve cadaveric knees were dissected through the lateral approach. The common peroneal nerve was identified and traced. The location where the common peroneal nerve crossed the posterior border of the biceps femoris and the posterior border of the fibular neck were designated as points B and N, respectively...

BACKGROUND: Missed posterolateral corner (PLC) injuries are a known cause of anterior cruciate ligament reconstruction (ACL) failure in the adult population. Failed ACL reconstruction causes significant morbidity in the skeletally immature pediatric population. There is little literature on the character and potential significance of PLC injuries in skeletally immature patients. METHODS: Magnetic resonance imaging studies of the knee at a tertiary care children's hospital for patients who underwent an ACL reconstruction without PLC surgery were retrospectively reviewed...

Comminuted proximal fibula fractures or arcuate fractures (OTA/AO 4F1B fractures), can defunction the posterolateral corner and result in posterolateral knee instability. Ongoing posterolateral knee instability can limit function, cause significant pain, and lead to early knee arthrosis. The anatomy of the posterolateral corner and proximal fibula limit the options for repair of this injury. The ideal method for osteosynthesis of these injuries has not been established. The goals of treatment include reconstitution of posterolateral stability, restoration of the anatomic relationship of posterolateral corner structures, and restoration of bone stock that would permit future reconstruction...

PURPOSE: There has been a recent resurgence in interest in posterolateral instabilities of the knee joint. As this terminology comprises a large variety of pathologies, confusion and ambiguity in communication between surgeons and allied health professionals are generated. Consequently, accurate classification criteria are required to account for thorough preoperative diagnostics, surgical decision-making, and a standardized scientific documentation of injury severity. METHODS: A working group of five knee surgeons, who retrospect more than 2000 reconstructions of the posterolateral corner (PLC) at the minimum, was founded...

We report the case of a six-year-old male child with progressive pain and swelling of the right shoulder for six months. On examination, there was a 7x7 cm globular, tender swelling with firm consistency over the posterolateral corner of the right shoulder. Radiographs showed an expansile lytic lesion in the acromion process of the scapula. Biopsy showed lobules of hypocellular cartilage separated by fibroconnective stroma suggestive of an enchondroma. Extended curettage and fibular bone grafting of the lesion was done...

We present an unusual and complex case of a 16-year-old adolescent male who injured his right knee and sustained combined avulsion injuries of posterior cruciate ligament (PCL) at the tibial insertion site, iliotibial band at lateral tibial condyle, and lateral collateral ligament (LCL) at femoral insertion site akin to osteoligamentous posterolateral corner injury. Anatomical reduction of the femoral LCL avulsion fragment was performed and fixed with a two 4-mm partially threaded cancellous screw. Iliotibial band avulsion was buttressed using Ellis t-plate and fixed with two 4-mm partially threaded cancellous screws...

Two decades ago, it was not uncommon to call the posterolateral corner of the knee the "dark side of the knee." This was because there were few quantitative anatomic data, no anatomic-based reconstructions, and a high rate of clinical outcome failures. Most nonanatomic posterolateral reconstruction procedures at the time commonly resulted in significant recurrent increases in varus gapping and significant overconstraint in external rotation. Postoperative protocols for treating these injuries were designed to often either cast or immobilize the operative knee for 2 to 6 weeks, which resulted in a higher incidence of arthrofibrosis...

The negative consequences of neglected posterolateral corner injury (PLC) have led to numerous advancements in the understanding and treatment of these injuries. As anatomic, biomechanical, and clinical knowledge of PLC injury continues to progress, finding the balance between re-creating native anatomy and safely performing PLC reconstruction continues to provide challenges to surgeons managing this complex constellation of injuries.

Historically described as the "dark side of the knee," the posterolateral corner of the knee has been a significant focus of anatomic, biomechanical, and clinical outcomes research due to poor treatment outcomes for these injuries before improvements over the past 2 decades. These research efforts have resulted in significant improvements in the understanding, diagnosis, and surgical treatment of these injuries. Perhaps most importantly, improved understanding of the anatomy and biomechanics has led to the development of anatomic-based reconstructions, which have been subsequently validated with both biomechanical and clinical outcomes...
