“…A few studies on the diagnosis of DLM using ultrasonography have been published. In addition to our previous study, Arifa Achour et al 24 qualitatively summarised the ultrasonic imaging characteristics from eight cases of children with DLM, and Yang et al 26 explored the diagnostic value of convex and linear array probes for DLM in children. The present study is the first to use quantitative ultrasound parameters to diagnose DLM and its classification in children.…”

Feasibility and efficacy of ultrasound in the diagnosis of discoid lateral meniscus and its classification in children: protocol for a prospective, multicentre, diagnostic test study

IntroductionAlthough ultrasound can reportedly diagnose discoid lateral meniscus (DLM) in children, its widespread application is challenging because the diagnostic criteria are based on qualitative descriptions of DLM morphology rather than quantitative parameters. Additionally, no studies have applied ultrasound in classifying DLM. Therefore, this study aims to establish the quantitative ultrasound parameters that reflect DLM morphology, evaluate the feasibility and validity of these parameters for identifying DLM and their classification, and develop the quantitative ultrasound diagnostic criteria for DLM and their classification in children.Methods and analysisPatients will be recruited from the outpatient clinics of the orthopaedics department at West China Hospital, Sichuan University, the Fourth Medical Center of the Chinese People’s Liberation Army General Hospital, Xinhua Hospital affiliated with Shanghai Jiao Tong University School of Medicine, Yibin Hospital affiliated with West China Hospital Sichuan University, Suining Central Hospital and the Third Hospital of Mianyang from August 2022 to July 2024. Eligible patients are those aged ≤14 years, with knee symptoms such as pain, locking and limited extension, and who planned to undergo arthroscopic surgery. Exclusion criteria are patients with contraindications to ultrasound examination, such as severe skin damage or fracture around the knee. The sample size is estimated to be 576 cases with a power of 0.9 for hypothesis testing, a two-sided α of 0.05, and an expected sensitivity and specificity of 95%. Three days before surgery, ultrasound will be used to observe the morphology of the lateral meniscus and measure its width, angle α formed by the chord of upper and lower arc-shaped articular surface at the free edge, and the movement distance of the peripheral rim. Participants will be categorised according to the arthroscopy results for the DLM and its classification. The diagnostic performance of each parameter will be assessed and compared in terms of the area under the curve, sensitivity, specificity, and positive and negative predictive values.Ethics and disseminationThis study was approved by the Ethics Committee of West China Hospital, Sichuan University (approval no. 2022-923), and this approval covers all study hospitals. Written informed consent is required from all participants before enrolment in the study. The study’s findings will be disseminated through peer-reviewed publications and conference presentations.Trial registration numberChinese Clinical Trial Registry (ChiCTR2200062000).

“…The real-time dynamic observation, the unique advantages of ultrasound, may enable it to become a reliable new method for diagnosing DLM and its classification and lesions. 41,[118][119][120]199 In recent years, there are many studies about the diagnosis of X-ray on DLM and its classification, but X-ray can only be used as an indicative diagnostic method because its diagnostic value is influenced by measuring error and the distance between the X-ray tube and knee joint. [17][18][19][123][124][125][126][127][128][129] The key points of DLM treatment are restoring the normal shape, retaining the appropriate width and thickness, and preserving the remnant meniscus's stability.…”

“…The accuracy of ultrasonography in diagnosing meniscus lesions is comparable to that of MRI, but the diagnosis of DLM and its classification and lesions is potential and still in the preliminary exploration stage.

“…Ultrasonography has unique advantages and high application value in diagnosing musculoskeletal diseases, especially for meniscus tears, 115,116 but diagnosing DLM and its lesions is still in the exploration stage. 117 Achour et al 118 found sonographic features of DLM in children: (1) the absence of a normal triangular shape; (2) an abnormally elongated and thick meniscus; (3) a heterogeneous central pattern. However, this qualitative description is more subjective and influenced by the examiner's experience.…”

Discoid lateral meniscus (DLM) is the most common congenital variant of the lateral meniscus, which is prone to degeneration and lesions, and often leads to knee osteoarthritis. At present, there is no consensus on the clinical practice of DLM, and this expert consensus and practice guidelines on DLM was developed and approved by Chinese Society of Sports Medicine according to the Delphi method. Among 32 statements drafted, 14 statements were excluded for redundant information, and 18 statements achieved consensus. This expert consensus focused on the definition, epidemiology, etiology, classification, clinical manifestations, diagnosis, treatment, prognosis, and rehabilitation of DLM. Restoring the normal shape, retaining appropriate width and thickness, and ensuring the stability of the remnant meniscus is critical to sustaining the physiological function of the meniscus and preserving the knee. The partial meniscectomy with or without repair should be the first-line treatment when possible, given that the clinical and radiological long-term outcomes of total or subtotal meniscectomy are worse.
