Medial meniscus posterior root tears (MMPRT) can lead to meniscal extrusion, loss of hoop tension, loss of load-sharing ability and increased contact pressure. Currently, the most commonly used technique for root repair is arthroscopic transtibial pullout repair (ATPR). This article aims to illustrate both normal and abnormal postoperative imaging findings of the MMPRT repair performed with ATPR, with emphasis on MRI. The radiologist must highlight the tunnel position, the reduction of the medial meniscus posterior root to its anatomical attachment, the signs of root healing (continuity and lower signal intensity), and eventual meniscal extrusion or signs of osteoarthritis.

Case: A 16-year-old woman presented with acute on chronic knee pain and instability following a twisting injury. The tibial insertion of the anterior cruciate ligament (ACL) was nonvisualized on magnetic resonance imaging. A cord-like ACL, originating from the lateral intercondylar notch and inserting smoothly into the anterior horn of the intact lateral meniscus, was found on arthroscopy.

Objectives: Dietary interventions are a potentially powerful treatment option for knee osteoarthritis (OA). The objective of this study was to evaluate a well-formulated ketogenic diet (KD) in the context of knee OA histology and pain using the destabilization of the medial meniscus (DMM) mouse model and correlate with gut microbiome and systemic cytokine levels.
Methods: Adult male mice underwent unilateral DMM or sham surgery and were then fed eight weeks of KD or chow.

The anterior cruciate ligament (ACL) is a major ligament in the knee joint, and its function is crucial for both the movement and stability of the knee. Our research takes a novel approach by investigating the effect of meniscus tears on the ACL, how such tears will impact the stress on the ACL, and its overall compensation in response to the changes in the meniscus. : This study aims to investigate how the ACL compensates for the change in knee joint stability and contact pressures due to partial horizontal cleavage tears (HCTs) in the meniscus, such as partial meniscectomy and partial transplantation on knee joint stability and contact pressures.

PubMed and Medline databases were searched in October 2023 for studies reporting outcomes of arthroscopic anterior cruciate ligament (ACL) reconstruction and stable medial meniscal ramp lesion treatment. Studies focused on diagnostic approaches, biomechanical properties, unstable ramp lesions, isolated ramp lesions, and concomitant intraarticular/extraarticular pathologies other than ACL rupture are excluded.

Objective: To measure and analyze the relationships among the posterior tibial slope (PTS), meniscal slope (MS), and meniscus posterior horn thickness (MPHT) of the medial and lateral tibial plateau in healthy people and patients with anteromedial osteoarthritis (AMOA) in Heilongjiang province, so as to provide reference basis for appropriate tibial osteotomy and prosthesis placement angles in knee joint surgeries.
Methods: A retrospective collection of imaging data from knee joint MRI examinations conducted prior to AMOA for various reasons was performed. A total of 103 healthy individuals (healthy group) and 30 AMOA patients (AMOA group) were included.
