Magnetic resonance imaging of the knee is greater than 90% accurate in detecting intraarticular disease when performed and interpreted by musculoskeletal magnetic resonance imaging specialists in specialized medical centers. However, independent imaging institutions often offer less expensive services to health insurers. We wondered if the magnetic resonance imaging performed in our community i...

BACKGROUND Knowledge of the impact of viable medial meniscus allograft and autograft transplantation on biochemical and mechanical properties of cartilage is needed to understand the development of joint osteoarthritis. The purpose of this study was to evaluate this relationship 6 months after viable medial meniscal autograft and allograft transplantation. METHODS Twenty rabbits were chosen f...

Meniscal Ossicle are a rare clinical entity with an incidence of only 0,15% [1]. However, it may cause functional limitations and its diagnosis is confused with other knee pathologies. We shall share here our experience in the diagnosis and surgical treatment of a case of meniscal ossicle by arthroscopy, utilizing the anterolateral and anteromedial portals, with intercodylar and posteromedial p...

The human knee menisci are important structures to, proper knee joint function. At present, little data exists describing the meniscal kinematics of the intact knee. Accordingly, the purpose of this study was to determine in-vivo meniscal kinematic motion of the non-injured knee during unloaded knee flexion through use of magnetic resonance imaging (MRI). Seven females and three males (mean age...

INTRODUCTION This technical note describes a new arthroscopic technique to repair the peripheral attachment lesion of the posterior horn of the medial meniscus. The operation was performed under arthroscopy using a standard anterior portal. SURGICAL TECHNIQUE A FasT-Fix needle was inserted obliquely close to the tibial plateau and the first implant was inserted into the joint capsule dependin...

Introduction The knee menisci are heterogeneous fibrocartilages with regional variations in phenotype and extracellular matrix composition reflecting varying functional demands. The inner (compressive) region is generally described as closer to cartilage, with higher aggrecan and collagen II contents and rounded fibrochondrocytes resembling articular chondrocytes, while the outer (tensile) thir...

PURPOSE To retrospectively determine the prevalence of posterior lateral meniscus root tears (LMRTs), as depicted on magnetic resonance (MR) images, in patients with an anterior cruciate ligament (ACL) tear and to investigate the association of LMRTs with lateral meniscus extrusion and other ligament injuries. MATERIALS AND METHODS Institutional review board approval was obtained; informed co...

Clinical, arthrographic, and arthroscopic findings in 53 patients with acutely torn anterior cruciate ligaments (ACLs) were documented. Arthroscopy and instability tests under anesthesia were performed on all patients within 2 weeks after the initial injury. Twenty-three patients complained of extension blocks, and localized tenderness on the medial side was revealed in 26 patients at the initi...

The purpose of this study was to document the pattern ligament and meniscal injuries that occur with proximal tibia fractures due high energy trauma. Seventy patients high-energy mechanisms were evaluated magnetic resonance imaging (MRI) knee. All studies reported by a single musculoskeletal radiologist who blinded surgical physical findings. Of 70 patients, there 42 AO/OTA type 41B2 (60%) frac...
