“…In addition, activity level was not found to be correlated with clinical outcomes. Similarly, Sasho et al [20] reported that high activity levels were not a risk factor for DLM requiring surgical treatment. Therefore, BMI and activity level alone are unlikely to explain the risk of DLM progression over time.…”

PurposeThe treatment for symptomatic intact discoid lateral meniscus (DLM) is controversial and the long-term clinical outcome remains unknown. The purpose of this study was to analyze the overall failure rate of nonsurgical treatment for symptomatic intact DLM and identify the risk factors for nonoperative management failure. Methods Consecutive patients who underwent nonsurgical treatment for symptomatic intact DLM at our hospital from 2014 to 2017 were retrospectively reviewed. Patients were divided into Group A (failure group) and Group B (nonfailure group) based on overall failure criteria: conversion to surgery, progression of a tear on MRI re-examination, or severely abnormal International Knee Documentation Committee (IKDC) scores. Statistical analyses between the two groups were performed for demographic and radiographic characteristics. Multivariate regression analysis was used to determine the risk factors associated with worse outcomes. Results One-hundred and four knees in 96 patients were included in this study. After a mean follow-up of 76.9 ± 11.1 months, 25 knees (24.0%) met the overall failure criteria. Multivariate regression analysis demonstrated that age and the presence of intrameniscus signals increased the risk of nonoperative management failure. The clinical criterion of age > 37.5 years combined with the imaging criterion of the presence of intrameniscal signals predicted conservative treatment failure of symptomatic intact DLM with a sensitivity of 0.87 and a speciicity of 0.91. Conclusion Twenty-ive (24.0%) knees that underwent nonsurgical treatment met the overall failure criteria after a mean follow-up of 76.9 months. With increased age and the presence of intrameniscal signals, the nonoperative results become worse. Level of evidence III.

“…47,109,110 In patients with unilateral symptomatic DLM, the probability of DLM in the contralateral knee is about 73%-97%, 6 and of the same type in both is 88%. 6,111,112 Therefore, MRI should be recommended for the contralateral knee to confirm whether it is DLM or discover the obscure lesion 6,47,113,114 (Grade B1).…”

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.

“…Ó surgery in the contralateral knee. Sasho et al 12 reported that the risk of needing surgical treatment on the contralateral knee was high in the first 2 years following the initial surgery. This finding could indicate a high vulnerability of the contralateral knee during the early rehabilitation phase.…”

Recent reports have found the rate of bilateral discoid lateral meniscus (DLM) to be high (79%-97%) in patients with unilaterally symptomatic DLM; the associated torn meniscus incidence is also high at 33%. The present study results indicated that older, symptomatic DLM patients with more degenerative changes may be at risk for a similar condition in the contralateral knee. Long-term follow-up with magnetic resonance imaging screening for asymptomatic contralateral knees is necessary to determine the fate of the contralateral knee.
