“…However, there are also many practical advantages to studying these tendons, that thereby constitute complications when assessing the collateral ligaments. First, in contrast to the thick and broad Achilles and patellar tendons, the collateral ligaments are small, with complex anatomy (Table 1), and can be difficult to identify on ultrasound; the rope-like lateral collateral ligament (LCL) typically extends from the lateral femoral epicondyle to the fibular head, where it first conjoins with the biceps femoris tendon (Otake et al, 2007; Shin et al, 2014), though significant anatomical variation exists (Shin et al, 2014), and the flat and thin medial collateral ligament (MCL) (Otake et al, 2007) is composed of multiple structures (Robinson et al, 2002) that also display distinct mechanical properties (Robinson et al, 2005). …”

Ultrasound-based methods have shown promise in their ability to characterize non-uniform deformations in large energy-storing tendons such as the Achilles and patellar tendons, yet applications to other areas of the body have been largely unexplored. The noninvasive quantification of collateral ligament strain could provide an important clinical metric of knee frontal plane stability, which is relevant in ligament injury and for measuring outcomes following total knee arthroplasty. In this pilot cadaveric experiment, we investigated the possibility of measuring collateral ligament strain with our previously validated speckle-tracking approach, but encountered a number of challenges during both data acquisition and processing. Given the clinical interest in this type of tool, and the fact that this is a developing area of research, the goal of this article is to transparently describe this pilot study, both in terms of methods and results, while also identifying specific challenges to this work and areas for future study. Some challenges faced relate generally to speckle-tracking of soft tissues (e.g. the limitations of using a 2D imaging modality to characterize 3D motion), while others are specific to this application (e.g. the small size and complex anatomy of the collateral ligaments). This work illustrates a clear need for additional studies, particularly relating to the collection of ground-truth data and more thorough validation work. These steps will be critical prior to the translation of ultrasound-based measures of collateral ligament strains into the clinic.

“…We thought that this angle might be related to the distal variative insertion of the LCL and SI of the proximal LCL. Typically, LCL attaches to the head of the fibula in the form of a conjoint tendon formed with the biceps femoris tendon, but it can also attach with various extensions to the lateral plateau of the tibia and the fibular head (6). In our study, we formed three groups to evaluate this variation according to their insertions to make MRI examination simpler.…”

“…It lies between the lateral condylar region of the femur and classically the head of the fibula (2,3). However, the distal attachment site may vary (4–6). The LCL is more important in limiting varus stress than other posterolateral corner structures (7).…”

Background Hyperintensity in the proximal lateral collateral ligament (LCL) is often confusing. This appearance may be alone or accompany other pathologies. Purpose To investigate the relationship between the signal intensity (SI) change in the proximal LCL and the knee joint pathologies. Material and Methods The knee MRI scans taken between 2020 and 2022 were queried retrospectively. Patients with acute trauma, instability, knee surgery, or high-grade osteoarthritis were excluded. Included patients were divided into two groups as normal SI and increased SI according to proximal LCL. The difference in ligamentous and meniscal pathologies between the two groups was analyzed using a chi-square test. Inter-observer agreement analysis was performed on 50 randomly selected patients. Results A total of 351 patients (139 men [39.6%], 212 women [60.4%]; median age = 37 years; interquartile range = 67 years) were included. There were 114 (32.5%) LCLs with normal SI and 237 (67.5%) LCLs with increased SI. Normal SI and increased SI groups had a significant difference in terms of joint side, median age, patellar tendon SI, anterior cruciate ligament SI, and medial collateral ligament SI ( P = 0.004, P = 0.004, P = 0.001, P = 0.011, P = 0.004, respectively). A significant difference between the results of two separate LCL examinations in coronal + axial and coronal-only planes ( P <0.001). Inter-observer agreement was found to be good to excellent. Conclusion Hyperintensity in the proximal LCL was more common on the right joint side, in older patients, and patients with hyperintensity in the proximal patellar tendon, anterior cruciate ligament, and medial collateral ligament. Evaluating the LCL only in the coronal plane overestimates the hyperintensity.
