At present, there few studies on the kinematic features of lateral discoid meniscus injury. In this study, a motion capture system was used to investigate the motion characteristics of knees with lateral discoid meniscus after injury, and the differences between the knees with lateral meniscus and intact knees were compared. Fourteen patients diagnosed with unilateral lateral discoid meniscus injury, fourteen patients diagnosed with unilateral lateral meniscus injury, and fourteen normal subjects with healthy knees were recruited and grouped...

Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: Radiographs of pediatric patients with arthroscopically confirmed lateral discoid menisci were compared with age-, side-, and sex-matched individuals with confirmed normal menisci...

Arthroscopic partial resection is indicated for patients who have symptomatic discoid meniscus with overall satisfactory clinical outcomes. Reports regarding regeneration of discoid meniscus after arthroscopic surgery are limited. There are only two reports for children in the literature. To the authors' knowledge, the present study is the first report in the literature to report regeneration of discoid lateral meniscus after arthroscopic partial meniscectomy in an adult patient. The diagnosis was confirmed by both magnetic resonance imaging and arthroscopy...

Objective: To examine the clinical and functional outcomes for a series of patients who underwent meniscal repair for isolated meniscal tears focusing the study population on athletes. Methods: This study represents a case series of 46 athletes who underwent repair of isolated meniscal lesions of the knee from 2010 to 2015. Cases of discoid meniscal lesions and combined ligament injuries were excluded. The mean age of the patients was 22.9 years ranging from 12 to 50 years...

Preservation of the meniscus has been shown to influence the progression of degenerative changes of the knee. As more meniscus is preserved, the propensity for development of osteoarthritis is lessened. Surgical treatment of a torn discoid meniscus has typically been a subtotal meniscectomy or partial meniscectomy. Similar to tears of a normal meniscus, partial meniscectomy compared with subtotal meniscectomy of the discoid meniscus confers better long-term results. With the abnormal morphology predisposing the discoid meniscus to tearing, several characteristic tear patterns can be observed-the horizontal tear being commonly encountered...

PURPOSE: The purpose of this study was to examine the long-term clinical outcomes of arthroscopic partial meniscectomy for the treatment of discoid lateral meniscus in children. METHODS: A previous study identified 34 consecutive patients that underwent arthroscopic meniscal saucerization by one of the two surgeons between 1997 and 2002. Patients were asked to complete several outcomes questionnaires and were given the opportunity to receive a knee exam performed by their treating surgeon...

PURPOSE: To develop prediction models to improve the diagnostic utility of plain radiographs for the diagnosis of complete discoid lateral meniscus by combining previously reported radiographic findings. METHODS: Patients ages 5 to 16 years with complete discoid lateral meniscus confirmed by arthroscopy or magnetic resonance imaging were included. Patients with insufficient radiographs were excluded. Normal control subjects were randomly sampled by age and sex matching...

INTRODUCTION: The aim of this study is to evaluate mid-to-long-term clinical and radiological outcomes after an arthroscopic partial meniscectomy for symptomatic discoid lateral meniscus (DLM) in young patients and to determine whether degeneration of the residual meniscus and articular cartilage progresses during the follow-up period using magnetic resonance imaging (MRI). MATERIALS AND METHODS: We retrospectively reviewed patients aged ≤ 40 years at surgery who underwent arthroscopic partial meniscectomy for symptomatic DLM and were followed up for ≥ 5 years...

RATIONALE: Bilateral discoid medial menisci is an extremely rare abnormality of the knee joint. The presence of a discoid medial meniscus has been associated with magnetic resonance imaging (MRI) and radiographic changes in the tibial region, such as cupping of the medial tibial plateau and tibial physis collapse. While discoid medial meniscal tears with hypoplasia of the femoral medial condyles have not been previously reported. Herein, we report a case of bilateral discoid medial menisci associated with meniscal tears and femoral bone changes...

The number of knee arthroscopies has increased rapidly since the 1980s and are among the most common orthopedic procedures today. It is generally considered a minimally invasive surgery with relatively low morbidity, but it is not without risk of complications. We report the case of a 14-year-old boy who developed a lesion of common peroneal nerve and tibial nerve after knee arthroscopy for a torn discoid lateral meniscus, which was confirmed by electromyogram study.

The discoid meniscus is a rare anomaly of the knee that affects mostly the lateral meniscus and is often asymptomatic. The osteochondritis dissecans is a disorder of the subchondral bone and articular cartilage and occurs frequently associated with the discoid lateral meniscus. In the present case, we showed the evolution of this association related to surgical treatment. A patient with lateral knee pain and a magnetic resonance depicting a torn discoid lateral meniscus and osteochondritis dissecans of the lateral femoral condyle was treated with partial meniscectomy and meniscal sutures...

PURPOSE: Discoid meniscus often causes mechanical problems and needs surgical treatment at an early age. However, many aspects of its morphological development and changes remain unknown. The purpose of this study was to investigate the insertion of the femoral anterior cruciate ligament (ACL) via the behind-ACL approach and the morphology of the lateral femoral condyle to which the ACL attaches to clarify the morphological characteristics of the knee with discoid lateral meniscus (DLM)...

Discoid meniscus is a congenital variant of the knee joint that typically involves abnormal morphology and potential instability of the lateral meniscus. Some discoid menisci have abnormal peripheral attachments and are unstable. Discoid menisci are prone to tearing secondary to increased thickness, poor tissue quality, and instability. Patients may or may not be symptomatic. Torn or unstable discoid menisci cause mechanical symptoms, pain, and swelling. Symptomatic patients in whom nonsurgical management fails most frequently are treated with arthroscopic surgery...

INTRODUCTION: Partial meniscectomy has been preferred in the treatment of discoid lateral meniscus (DLM) with tear, rather than total or subtotal meniscectomy, which could lead to late radiographic degenerative changes. HYPOTHESIS: One or more risk factors contribute to radiographic progression of osteoarthritis after partial meniscectomy of DLM tear. MATERIAL AND METHODS: Inclusion criteria were consecutive patients who underwent arthroscopic surgeries for DLM tear from January 2005 to December 2010 by one surgeon...

PURPOSE: MRI evaluation of torn lateral meniscus was compared with arthroscopy. This study calculates the sensitivity, specificity, and accuracy of MRI in determining the presence or absence of discoid lateral meniscus (DLM) for different tear types. METHODS: MR imaging of 156 knees with arthroscopically confirmed lateral meniscus tears was analysed. There were 78 knees (70 patients) in non-DLM group and 78 knees (74 patients) in DLM group on arthroscopy as the reference standard...

Lateral meniscus dislocation, as a cause of atraumatic knee locking, is often attributed to a discoid meniscus which can be readily diagnosed on MRI. In the absence of radiological abnormality, a dislocated lateral meniscus is a rare occurrence. We present a case of a 14 year old male who presented with atraumatic sequential locking of bilateral knees 6 months apart. Although on both occasions, MRI was normal, arthroscopy demonstrated dislocating lateral menisci that were subsequently surgically stabilised...
