“…Compared with the SLM group, the alignment in the DLM group was significantly more varus (p = 0.001). This difference may be related to the larger volume of the DLM 1,5,19 , which widens the lateral knee compartment and thus leads to a more varus alignment. The mean differences in the HKA and MAD between the 2 groups were 0.8° and 2.5 mm, respectively.…”

Background:A discoid lateral meniscus (DLM) is more prone to tear, and treatment of this condition is challenging. The purpose of the present study was to investigate (1) whether a torn DLM is associated with more varus alignment than a torn semilunar lateral meniscus (SLM) and (2) whether the lower-limb alignment associated with a torn DLM changes with age.Methods:Consecutive patients who underwent arthroscopic knee surgery for a torn lateral meniscus were included. Patients with a torn DLM (confirmed on arthroscopy) were allocated to the DLM group; those with a torn SLM were allocated to the SLM group. After strict screening according to the inclusion and exclusion criteria, 436 and 423 patients were included in the DLM and SLM groups, respectively. The mechanical axis deviation (MAD), hip-knee-ankle angle (HKA), mechanical lateral distal femoral angle, and medial proximal tibial angle were compared between the 2 groups after propensity score matching. Additionally, the correlation of the HKA and MAD with age was evaluated within the DLM group.Results:After propensity score matching, all baseline characteristics were well balanced between the 2 groups. The DLM group had significantly more varus alignment than the SLM group (MAD: 3.6 mm ± 9.6 mm versus 1.1 mm ± 10.3 mm, respectively, p = 0.001; HKA: 179.1° ± 2.9° versus 179.9° ± 3.0°, respectively, p = 0.001). Within the DLM group, the MAD (R = 0.10, p = 0.032) and HKA (R = −0.13, p = 0.007) had a weak correlation with age.Conclusions:Patients with a torn DLM had more varus knee alignment than those with a torn SLM, and this trend did not increase with age after minimizing the effects of osteoarthritis. Therefore, surgical treatment may not be appropriate for asymptomatic DLM.Level of Evidence:Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

“…Other anatomical variants, like a more distal location of the footprint of the posterior cruciate ligament (PCL) as well as the presence of a discoid lateral meniscus (DLM) may further affect the mechanical environment in the knee. 4 , 33 , 34 Complete discoid menisci were associated with a central OCD, while incomplete discoid menisci were associated with peripheral OCD. 35 Mitsuoka et al 36 even reported a case of OCD with a complete DLM in a 10-year-old male that completely healed after partial arthroscopic meniscectomy, without specific treatment for the osteochondral lesion of the LFC.…”

Osteochondritis dissecans of the knee is a disease that typically affects skeletally immature patients. Clinically manifested with knee pain, limping, and joint disfunction, this condition has remained misunderstood and undervalued for a long period. Although being a rare condition, its awareness is of utmost clinical interest because of the possible severe consequences it can bring when misrecognized or inadequately treated. Its etiology remains unclear and is still debated. Many theories have been proposed, including inflammation, local ischemia, subchondral ossification abnormalities, genetic factors, and repetitive mechanical microtrauma, with a likely interplay of the same. This review article aims to deliver and discuss current and up-to-date concepts on epidemiology, etiology, and natural history of this pediatric condition. Level of evidence: level V.

“…Nonetheless, this hypothesis cannot reasonably explain the formation of complete DLM or incomplete DLM with normal meniscus-tibial ligament and without high mobility and repeated impingement. 8 DLM was reported to have the family aggregation 16,57,[64][65][66] and was found to complicate with achondroplasia, [67][68][69][70] Turner syndrome, 71 and anterior cruciate ligament hypoplasia, 72 which leads to speculation that DLM may be a congenital genetic disease of meniscus dysplasia. However, these results are still in the preliminary exploration stage, lacking studies on the specific molecular mechanism and functional verification.…”

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.
