Associated Medial Meniscal Injury with ACL Reconstruction Results in Poorer Strength and Jump Tests Outcomes: A 6-Month Analysis of 504 Patients from the MERIScience Cohort.

: After anterior cruciate ligament reconstruction (ACLR), a 6-month composite test is recommended during rehabilitation before the return to sport, and the influence of a meniscal tear is not known. The hypothesis was that the location and treatment of meniscus injuries could influence the results of the composite test. : A retrospective single-center study was carried out of prospectively collected data involving 504 patients who performed a composite test 6 months after ACLR.

Knee osteotomy combined with meniscal allograft transplantation versus knee osteotomy alone in patients with unicompartmental knee osteoarthritis: a prospective double-blind randomised controlled trial protocol.

Introduction: Knee osteotomy combined with meniscal allograft transplantation (MAT) showed promising results to treat unicompartmental knee osteoarthritis (OA) secondary to meniscal deficiency and knee malalignment. However, there is still no high-level evidence to demonstrate whether the combination of these two treatments is superior to osteotomy alone.

Methods And Analysis: 52 patients with unicompartmental knee OA Kellgren-Lawrence grade ≤3 secondary to meniscal deficiency and knee malalignment (aged 20-60 years) are randomised to undergo knee osteotomy associated with MAT or knee osteotomy alone in a 1:1 ratio.

Extension patellar engagement index: a new measurement of patellar height.

Introduction: Patellar instability is a multifactorial pathology requiring precise evaluation of its contributing factors, particularly patella alta. Patellotibial height measurement indexes, such as the Caton-Deschamps index, have the disadvantage of being referenced to the tibia. Patellotrochlear indexes are more appropriate but fail to account for variable knee flexion during magnetic resonance imaging (MRI).

The clinical potential of meniscal progenitor cells.

Introduction: The meniscus is an important cushioning structure of the knee joint, with the maintenance of its normal structure and function playing a crucial role in protecting the joint from early degeneration. Stem/progenitor cells could be the key to help researchers to have a deeper understanding of the biological process of meniscal injury repair and may be important in the meniscus tissue regeneration processes. To the best of our knowledge, there is currently a lack of comprehensive reviews on existing research about the meniscus progenitor cells (MPCs).

Arthroscopic meniscal surgery in Norway from 2010 to 2020: A paradigmatic shift.

Purpose: Meniscal injuries in the knee are usually treated surgically with arthroscopic partial resection (APR) or arthroscopic repair (AR). APR has been shown to increase the risk of osteoarthritis and the focus has shifted to repairing the meniscus with AR. The extent of this shift is yet to be established and an analysis of incidence rates (IR) of APR and AR for meniscal injuries could highlight this.

Lateral Meniscal Tears Can be Safely Repaired "All-Inside" Without Peroneal Nerve Injury: Case Series and Literature Review.

Introduction: The menisci are a pair of fibrocartilaginous structures important for the normal biomechanical function of the knees. Tears are common, and multiple approaches have been used to repair meniscal tears. Of the approaches, the all-inside approach has historically been avoided for tears to the posterior aspect of the lateral meniscus (LM) due to the risk of popliteal and common peroneal neurovascular injury.

Evaluation of meniscal injury on magnetic resonance imaging and knee arthroscopy in patient with anterior cruciate ligament tear.

Introduction: Meniscal injuries often occur in association with anterior cruciate ligament (ACL) injury. Failure to detect meniscal tears in patients with ACL injuries can lead to more complex tears and make them more difficult to repair.

Objective: To determine the degree of correlation between magnetic resonance imaging (MRI) and knee arthroscopy in diagnosing meniscal injuries in patients with ACL tears.

The Molecular Mechanism Investigation of HBP-A Slows Down Meniscus Hypertrophy and Mineralisation by the Damage Mechanical Model.

HBP-A is the main active component of a traditional Chinese medicine Huaizhen Yanggan Capsule, for the remarkable treatment of knee osteoarthritis (KOA). This study aimed to elucidate the ameliorative effect of HBP-A on meniscus hypertrophy and mineralisation in KOA and the molecular mechanism of its action. An Hartley guinea pig model of KOA that underwent anterior cruciate ligament transection (ACLT) and a model of rat primary meniscus fibrochondrocytes (PMFs) were used to investigate the ameliorative effect of HBP-A on meniscal hypertrophy and calcification and its signal transduction mechanism of action.

Tibial Spine Fractures.

Tibial spine fractures (TSFs) are a relatively uncommon knee injury that most commonly occurs in skeletally immature pediatric patients following a sports or bicycle-related injury. Treatment of TSFs is guided based on fracture displacement on radiographs and associated injuries. Surgical treatment is recommended for displaced TSFs with arthroscopic or open reduction and fixation.

Analysis of microvascular density and collagen structure of the medial meniscotibial ligament of the knee: Immunohistochemical study with CD31 and histology with Picrosirius red.

Background: The aim of the present study was to describe the structure of the collagen matrix and the microvascularization of the medial meniscotibial ligament (MMTL), in order to contribute to the refinement of the surgical technique for repairing these structures and consequently lead to a reduction in the risk of anterior cruciate ligament re-rupture.

Methods: Twelve MMTLs were obtained from deceased organ donors. The ligaments were initially analyzed macroscopically and evaluated histologically using hematoxylin and eosin staining.

Longer time between anterior cruciate ligament injury and reconstruction is associated with a greater risk of medial meniscus injury.

Purpose: To evaluate the impact of delaying reconstruction following anterior cruciate ligament (ACL) injury on the risk of meniscal injury and subsequent meniscectomy, the study was carried out. This constitutes the first study of its kind to be conducted in China.

Methods: This study collected data on patients who had undergone ACL reconstruction surgery at Peking University First Hospital between 2010 and 2022.

The effectiveness of microfracture augmentation on the wall of femoral condyle in meniscal healing among patients with meniscus tears after sports injury.

Background: Meniscus injuries are familiar sources of knee pain, with meniscus repair sometimes yielding unsatisfactory results. Microfracture is a standard procedure for treating articular cartilage damage in the knee that promotes the formation of fibrocartilage over damaged cartilage. Microfracture enhanced the healing rate of meniscus repair in animal models.

Age under 20 years, pre-operative participation in pivoting sports, and steep posterior tibial slope of more than 12° are risk factors for graft failure after double-bundle anterior cruciate ligament reconstruction.

Purpose: Younger age and steep posterior tibial slope (PTS) have been reported as risk factors for graft failure after anterior cruciate ligament reconstruction (ACLR). Few studies have evaluated these risk factors simultaneously in a large cohort of patients undergoing double-bundle ACLR (DB-ACLR). Therefore, this retrospective study aimed to simultaneously investigate known risk factors such as PTS and age in DB-ACLR, determine their thresholds and calculate odds ratios (ORs).

Anterior Cruciate Ligament Reconstruction in Patients Older Than 50 Years: A Descriptive Study With Minimum 10-Year Follow-up.

Background: Anterior cruciate ligament (ACL) reconstruction is increasingly being performed in patients >50 years old; however, the long-term outcomes are unclear.

Purpose: To analyze the functional results, osteoarthritic progression, reoperation rate, and failure rate at minimum 10-year follow-up in patients >50 years old who have undergone primary ACL reconstruction.

Study Design: Case series; Level of evidence, 4.

Multitask learning for automatic detection of meniscal injury on 3D knee MRI.

Magnetic resonance imaging (MRI) of the knee is the recommended diagnostic method before invasive arthroscopy surgery. Nevertheless, interpreting knee MRI scans is a time-consuming process that is vulnerable to inaccuracies and inconsistencies. We proposed a multitask learning network MCSNet which efficiently introduces segmentation prior features and enhances classification results through multiscale feature fusion and spatial attention modules.

Augmentation with Bone Marrow Aspirate Harvested from the Iliac Crest for Horizontal or Radial Meniscal Tears Yields Favorable Healing Rates in Magnetic Resonance Imaging and Clinical Outcomes.

Background: As the importance of meniscus in joint function becomes more apparent, there is a growing interest in meniscus repair techniques. Notably, biological augmentation methods have shown promising results for meniscus healing, despite their challenges in practical implementation. The purpose of this study was to evaluate meniscus healing and clinical outcomes of meniscus repair with bone marrow aspirate for horizontal or radial tears.

Evaluation of the Effect of Menisci on Tibial Slope and the Correlation With Body Mass Index.

Background One of the important factors affecting the biomechanics of the knee joint is the posterior tibial slope which is the tibial plateau's anatomical inclination toward the posterior of the sagittal plane. This inclination, which affects anterior-posterior stability, is important for the kinematics of the knee joint. Changes in the tibial slope may cause a deficit in the stability and function of the knee joint.
