Radiological Identification of Injury to the Kaplan Fibers of the Iliotibial Band in Association With Anterior Cruciate Ligament Injury.

Am J Sports Med 2020 Jun 24:363546520931854. Epub 2020 Jun 24.

OrthoSport Victoria Research Unit, Richmond, Australia.

Background: Recent biomechanical studies have demonstrated that the Kaplan fibers (KFs) of the iliotibial band play a role in the control of anterolateral rotation of the knee. However, controversy exists regarding whether the KFs are injured in conjunction with anterior cruciate ligament (ACL) injury.

Purpose: To establish the prevalence of radiological injury to the KFs in the ACL-injured knee; to evaluate the effect of the time interval between injury and magnetic resonance imaging (MRI) on diagnosis of KF injury; and to assess for any association between KF injury and other qualitative radiological findings.

Deep MCL injury cases with arthroscopic findings of hypermobile medial meniscus: A report of six cases of arthroscopic meniscal suture repair.

Asia Pac J Sports Med Arthrosc Rehabil Technol 2020 Oct 9;22:1-4. Epub 2020 Jun 9.

Department of Sports Orthopedic Surgery, Kanto Rosai Hospital, 1-1 Kizuki Sumiyoshi-cho, Nakahara-ku, Kawasaki city, Kanagawa-pref, Japan.

MRI did not detect any abnormality in the medial meniscus besides high-intensity changes at the meniscofemoral portion of the deep medial collateral ligament. Although pure valgus stress test proved no medial joint widening at 0° and 30°, when an examiner applied knee valgus and tibial external rotation force, the patient experienced pain in the anteromedial knee joint that coincided with their refractory symptoms in individual specific activity. Arthroscopy investigation confirmed that the anterior to middle segment of the medial meniscus had excessively slid into the central direction by a probe-drawing manoeuvre; synchronous meniscal movement in the valgus and external rotation test was also observed.

Anterolateral ligament injuries on magnetic resonance imaging and pivot-shift testing for rotational laxity.

J Clin Orthop Trauma 2018 Oct-Dec;9(4):312-316. Epub 2017 Oct 7.

Department of Radiology, University of Miami Miller School of Medicine, Jackson Memorial Hospital, Miami, FL, United States.

Maintaining anterolateral rotational stability of the knee requires a complex set of structures, most notably the anterior cruciate ligament. However, lateral knee structures such as the anterolateral ligament (ALL) also play an important role. There has been controversy over the role the ALL plays in an ACL deficient knee to maintain rotational stability. Read More

Prediction of Meniscal and Ligamentous Injuries in Lateral Tibial Plateau Fractures Based on Measurements of Lateral Plateau Widening on Multidetector Computed Tomography Scans.

Biomed Res Int 2018 29;2018:5353820. Epub 2018 Jul 29.

Department of Pediatric Orthopaedic Surgery, Children's Hospital, Hamburg-Altona, Germany.

Background: The influence of increasing lateral plateau widening on the frequency of meniscal and ligamentous lesions in lateral tibial plateau fractures has been examined in very few studies using plain radiographs. Because the amount of this parameter cannot be measured accurately on plain radiographs, the purpose of this survey was to look for a possible correlation between the extent of lateral plateau widening, as measured on multidetector CT (MDCT) scans, and different soft-tissue injuries determined from magnetic resonance imaging (MRI).

Materials And Methods: 55 patients with a lateral tibial plateau fracture were included in this retrospective case series. Read More

Editorial Commentary: Is the Anterolateral Ligament Always Injured in Knee Dislocations? Does It Matter?

Arthroscopy 2018 06;34(6):1898-1899

Vail, Colorado.

Anterolateral ligament injuries with knee dislocations appear to be very common. In particular, those that occur with fibular (lateral) collateral ligament injuries are very frequent. Although the majority of injuries in this magnetic resonance imaging study appear to be at the proximal attachment of the anterolateral ligament, caution is advised because there is still no clear agreement as to the anatomic attachment site of the anterolateral ligament on the femur.
