Knee ligament and meniscus injuries in children and teenagers.

Knee ligament and meniscus injuries in children and teenagers are becoming more numerous because of increased sports participation but also better diagnosis. Meniscus injuries occur either in a normal meniscus or due to a congenital anomaly. The diagnosis is made clinically and confirmed by MRI.

Abnormal patella height may be an independent risk factor in meniscal tears: a retrospective study in paediatric patients.

Purpose: The literature on factors predisposing to meniscal tears in the paediatric population focuses on concomitant injuries such as anterior cruciate ligament rupture (ACL) or abnormal meniscus morphology such as discoid menisci. Patella alta has been associated with ACL ruptures but its association with meniscal tears has not been described. The purpose of our study was to evaluate whether abnormal patella height is associated with isolated meniscus tears in skeletally immature patients METHODS: We retrospectively analysed all patients under 16 years of age who had an isolated meniscal tear diagnosis confirmed on arthroscopic surgery.

Regeneration of a Discoid Meniscus: A Case Report.

Case: A 4-year-old girl with no relevant medical history presented with left knee swelling. Knee laxity, magnetic resonance imaging findings of anterior cruciate ligament (ACL) deficiency and discoid meniscus, and the chronicity of symptoms prompted arthroscopic ACL reconstruction and meniscal saucerization. Pain and swelling continued, and repeat arthroscopy revealed regeneration of the discoid meniscus at 18-month follow-up.

The management of isolated meniscal tears in skeletally immature children. An international expert consensus.

Purpose: The prevalence and appreciation of meniscal tears in children have increased in both number and complexity. There is currently a paucity of high-quality evidence that can guide surgeons in treating skeletally immature patients with meniscal injuries. The aim of this study was to develop comprehensive recommendations for the management of isolated meniscal tears in skeletally immature children.

MRI diagnostic performance and strategies for identifying retears in treated pediatric discoid and non-discoid lateral meniscal repairs.

Magnetic resonance imaging (MRI) plays a role in assessing retears of previously treated lateral menisci (LM). We aim to characterize the rate and pattern of arthroscopically confirmed LM retears in children with and without discoid morphology. 288 patients (312 knees) who underwent arthroscopic repair of isolated LM tears between 2018 and 2023 were identified.

Characteristics and Outcomes of Operatively Treated Discoid Lateral Meniscus in Pediatric and Young Adult Patients: A Multicenter Study.

Background: Discoid lateral meniscus (DLM) is the most common congenital abnormality of the meniscus. Tears are common; treatment is frequently not definitive, often requiring reoperation.

Purpose: To report the clinical manifestations, physical characteristics, operative treatments and findings, complications, and reoperations of DLM in pediatric patients from multiple centers across North America.

Failure rate of isolated medial meniscus repair in the stable knee: Systematic review and meta-analysis.

Purpose: The present meta-analysis aims to determine the outcomes and failure rates for medial meniscus repairs in patients with stable knees.

Methods: A literature search was conducted using PubMed and Scopus with the terms '(medial meniscus OR medial meniscal) AND (repair)'. The search strategy was based on the PRISMA (Preferred Reporting Items for Systematic Meta-Analyses) protocol and included 93 articles assessed for eligibility.

Case Report: Dislocation of lateral menisci secondary to congenital lateral tibiofemoral cartilage thickening in both knees.

A 24-year-old male patient complained of mild knee pain after jogging. The subsequent knee MRI demonstrated bilateral lateral thickened tibiofemoral cartilages, evidenced by deformities of the bilateral subchondral bone beneath the lateral femoral condyle cartilage. The corresponding dislocations of almost all the left lateral meniscus and part of the right lateral meniscus to the center of the joint were detected.

Clinical efficacy and pain follow-up after arthroscopic discoid meniscoplasty of the knee: a retrospective study.

Background: To assess the viability and efficiency of performing arthroscopic meniscoplasty in treating discoid meniscus (DM) in the knee joint.

Methods: A total of 29 patients diagnosed with symptomatic lateral DM between October 2014 and December 2019 were included in the study. Among them, 7 patients with intact DM underwent arthroscopic discoid meniscoplasty (group A), while 22 patients with torn DM received arthroscopic DM plasty along with repair and suturing (group B).

Long-term clinical and radiological outcomes after arthroscopic partial meniscectomy on stable knees are better for traumatic tears when compared to degenerative lesions: A systematic review.

Purpose: An arthroscopic partial meniscectomy (APM) for degenerative meniscus lesions and traumatic meniscus tears are two distinct entities and their long-term outcomes are rarely reported. The aim of this review was to compare the long-term (clinical and radiological) results of APM performed on stable knees for traumatic tears (TT) or degenerative lesions (DL).

Methods: Pubmed, Scopus and Embase databases were searched to identify relevant studies published between 2010 and 2023 using the keywords 'meniscectomy' OR 'meniscectomies' OR 'meniscal resection'.

Discoid meniscus: Treatment considerations and updates.

A discoid meniscus is a morphological abnormality wherein the meniscus loses its normal 'C' shape. Although most patients are asymptomatic, patients might still present with symptoms such as locking, pain, swelling, or giving way. Magnetic resonance imaging is usually needed for confirmation of diagnosis.

Excellent accuracy of magnetic resonance imaging for diagnosis of discoid meniscus tears: A systematic review and meta-analysis.

Purpose: The discoid meniscus (DM) is distinguished by its thickened, disc-shaped formation, which extends over the tibial plateau. The likelihood of developing osteoarthritis escalates if a DM tear remains undiagnosed and untreated. While DM tears can be diagnosed through arthroscopy, the high cost, invasive nature and limited availability of this procedure highlight the need for a better diagnostic modality.

Dynamic Magnetic Resonance Imaging Protocol: An Effective and Useful Tool to Assess Discoid Lateral Meniscus Instability in Children.

Objectives: One of the most common symptoms in cases of discoid lateral meniscus (DLM) in children is a "snapping" knee. The clock in extension, followed by a pop in flexion, perceived by the clinician, reflects the meniscal displacement caused by the peripheral meniscocapsular detachment. Standard magnetic resonance imaging (MRI) results in a 40% false-negative rate for detecting this instability.

Long Term Surgical and Radiological Outcome of Discoid Lateral Meniscus: An Updated Systematic Review.

Purpose Of The Study: This study aimed to reach a consensus for ideal surgical treatment of discoid lateral meniscus (DLM) and to evaluate its long term surgical and radiological outcome.

Methods: All authors independently searched for peer reviewed publications with keywords like discoid lateral meniscus, tibial menisci abnormalities, tibial menisci surgery and clinical outcome and their representative Medical Subjects Headings (MeSH) in databases of PubMed, EBSCO, Cochrane Central Register of Controlled Trials, from inception to December 2022. Original articles in English language on discoid lateral meniscus reporting clinical, surgical, or radiological outcomes with five or more years of follow-up were included in this systematic review.

Adults Have a Higher Incidence of Discoid Lateral Meniscus Tears Than Children-Adults Tend to Present With Complex Tears, While Horizontal Tear Patterns Are Frequently Encountered in Children: A Systematic Review.

Purpose: To systematically review the available literature on patients with discoid lateral meniscus (DLM) with the goal of elucidating the rates and types of meniscal tears, clinical symptoms, treatment strategies, and postoperative clinical and radiographic outcomes in adult patients compared with a pediatric population.

Methods: A literature search was performed using the PubMed, Embase, and Scopus databases from database inception to October 2023 according to the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Level of evidence I through IV human clinical studies evaluating rate and type of meniscal tears, clinical symptoms, patient-reported outcome measures, and postoperative radiographical assessments in patients with DLM were included.

Discoid LaterL Meniscus: A Concise Literature Update.

Discoid lateral meniscus (DLM) is the most frequent congenital variant of the lateral meniscus, which is prone to degeneration and tears, and frequently causes knee osteoarthritis. The purpose of this article has been to analyze the publications made during 2023 on DLM. The main conclusions of the analysis were as follows: MRI assessment might be helpful to diagnose DLM and detect the presence of instability: two main factors in the decision to perform surgery.
