The Segond's fracture and the anterolateral ligament.

J Anat 2021 Jun 23. Epub 2021 Jun 23.

Orthopaedic Unit and Kirk Kilgour Sports Injury Centre, S. Andrea Hospital, University of Rome Sapienza, Rome, Italy.

The study of Mullins et al. reasonably explains how the Segond's fracture is probably the most frequent avulsion fracture of the tibia plateau, but it does not challenge the hypothesis of the existence of a discrete ligament (the ALL) strong enough to sometimes pull out its bony insertion as a result of a forced internal rotation and of an ACL failure.

Editorial Commentary: Timing of the Combined Anterior Cruciate Ligament and Anterolateral Ligament Reconstruction: Still a Debatable Issue.

Yong Seuk Lee

Arthroscopy 2021 Jun;37(6):1918-1919

Seoul National University College of Medicine, Seoul National University Bundang Hospital.

Anterior cruciate ligament (ACL) injuries frequently occur as the results of twisting injury of the knee. Accompanying damages to other structures at the time of injury determine the severity of the injury, subsequent surgical procedures, and hence, clinical outcomes. Anterolateral ligament (ALL) seems to act as a side-bar of the ACL rather than a major ligament that should be reconstructed separately. Read More

Anterior cervical surgery to treat diffuse idiopathic skeletal hypertrophic combined with cervical disc herniation: A case report.

Medicine (Baltimore) 2021 Jun;100(22):e26097

Shenzhen Traditional Chinese Medicine Hospital, Shenzhen, China.

Rationale: Diffuse idiopathic skeletal hyperostosis (DISH) is a skeletal disease characterized by calcification of anterolateral ligaments of the spine and the rest of the body.

High Rate of Initially Overlooked Kaplan Fiber Complex Injuries in Patients With Isolated Anterior Cruciate Ligament Injury.

Am J Sports Med 2021 Jun 4:3635465211015682. Epub 2021 Jun 4.

Department of Orthopaedic Surgery, University of Connecticut, Farmington, Connecticut, USA.

Background: Injuries to the Kaplan fiber complex (KFC) are not routinely assessed for in the anterior cruciate ligament (ACL)-deficient knee during preoperative magnetic resonance imaging (MRI). As injuries to the KFC lead to anterolateral rotatory instability (ALRI) in the ACL-deficient knee, preoperative detection of these injuries on MRI scans may help surgeons to individualize treatment and improve outcomes, as well as to reduce failure rates.

Purpose: To retrospectively determine the rate of initially overlooked KFC injuries on routine MRI in knees with isolated primary ACL deficiency. Read More

Electromyographic Assessment of Anterior Cruciate Ligament Injury Risk in Male Tennis Players: Which Role for Visual Input? A Proof-of-Concept Study.

Diagnostics (Basel) 2021 May 30;11(6). Epub 2021 May 30.

Department of Medical and Surgical Sciences, University of Catanzaro "Magna Graecia", 88100 Catanzaro, Italy.

Anterior cruciate ligament (ACL) injury incidence is often underestimated in tennis players, who are considered as subjects conventionally less prone to knee injuries. However, evaluation of the preactivation of knee stabilizer muscles by surface electromyography (sEMG) showed to be a predictive value in the assessment of the risk of ACL injury. Therefore, this proof-of-concept study aimed at evaluating the role of visual input on the thigh muscle preactivation through sEMG to reduce ACL injury risk in tennis players. Read More

[Development of on-line lateral stiffness measurement system for anterior cruciate ligament and its influence on anterior cruciate ligament reconstruction].

Sheng Wu Yi Xue Gong Cheng Xue Za Zhi 2021 Feb;38(1):145-153

Sports Medicine and Joint Surgery Division, Zhejiang Provincial People's Hospital, Hangzhou 310014, P.R.China.

The anterior cruciate ligament (ACL) reconstruction mostly relies on the experience of surgeons. To improve the effectiveness and adaptability of the tension after ACL reconstruction in knee joint rehabilitation, this paper establishes a lateral force measurement model with relaxation characteristics and designs an on-line stiffness measurement system of ACL. In this paper, we selected 20 sheep knee joints as experimental material for the knee joint stability test before the ACL reconstruction operation, which were divided into two groups for a comparative test of single-bundle ACL reconstruction through the anterolateral approach.

Editorial Commentary: This Is the Way: Extra-Articular Augmentation Is an Essential Consideration in Contemporary Anterior Cruciate Ligament Surgery.

Arthroscopy 2021 05;37(5):1667-1669

Since the rediscovery of the anterolateral ligament, extra-articular augmentation (EA) has evolved from controversial to an essential consideration in contemporary anterior cruciate ligament reconstruction surgery. Anterolateral ligament (ALL) reconstruction and lateral extra-articular tenodesis are 2 common methods. Indications among early adopters pioneering anterolateral ligament reconstruction at anterior cruciate ligament surgery included revision anterior cruciate ligament (ACL) case, chronic ACL tear, high-grade pivot shift, and patients with hyperlax, hypermobile knees.

Editorial Commentary: Anterolateral Hinge Position Decreases the Slope in Opening-Wedge High Tibial Osteotomy: A Key Point in Treating an Anterior Cruciate Ligament-Deficient, Varus Knee.

Arthroscopy 2021 05;37(5):1585-1587

The orthopaedic surgeon who performs opening-wedge high tibial osteotomy (HTO) has to be aware of the behavior of the tibial slope depending on variations in the location of the hinge and in the inclination of the osteotomy. The most important point is that changing both the inclination and the rotation axis of the osteotomy cut affects the tibial slope. There is a natural trend to unintentionally increase the tibial slope when performing an opening-wedge HTO. Read More

J Knee Surg 2021 Apr 14. Epub 2021 Apr 14.

American Sports Medicine Institute, Birmingham, Alabama.

Injuries to the anterolateral ligament (ALL) of the knee are commonly associated with anterior cruciate ligament (ACL) ruptures. Biomechanical studies have demonstrated conflicting results with regard to the role of the ALL in limiting tibial internal rotation. Clinically, residual pivot shift following ACL reconstruction has been reported to occur up to 25% and has been correlated with poor outcomes. Read More

Division of Orthopaedic Surgery, Department of Medicine of Sensory and Motor Organs, Faculty of Medicine, University of Miyazaki, Kiyotake, Miyazaki 889-1692, Japan.

Osteotomy of the distal fibula or anterolateral corner of the tibia is usually required to fix a displaced osteochondral fracture of the talus that is located central to posterior area of the lateral talar dome. However, osteotomy is an invasive procedure and is associated with complications, including nonunion, persistent pain, and hardware-related problems. Lateral inverted osteochondral fracture of the talus (LIFT) lesion is an extremely rare type of displaced osteochondral lesion of the talus. Read More
