The discoid medial meniscus developed a horizontal cleavage tear and consequently a parameniscal cyst which became symptomatic insidiously. Physical examination revealed medial joint line tenderness with T...

Meniscal variations have increasingly been reported in medical literature. These anomalies mainly appear in the lateral side of the knee (Arnold et al., 2000). However, meniscal variations, such as discoid meniscus and hypoplasia, can also be found in the medial side (Cave and Staples, 1941; Min et al., 2001; Yañez-Acevedo, 2001; Tachibana et al., 2003; Monllau et al., 2006). The purpose of thi...

OBJECTIVE This work aimed to assess tibial rotations, meniscal movements, and morphological changes during knee flexion and extension using kinematic magnetic resonance imaging (MRI). METHODS Thirty volunteers with healthy knees were examined using kinematic MRI. The knees were imaged in the transverse plane with flexion and extension angles from 0° to 40° and 40° to 0°, respectively. The tib...

The objective of this study was to investigate the effect of partial longitudinal lateral meniscectomy on the mechanics of the knee joint. A 3D fibril-reinforced finite element (FE) model of the knee joint was used for this purpose. The model includes bones, cartilages, menisci as well as four major ligaments. The cartilages and menisci were modeled as fully saturated porous media reinforced by...

Background: Lateral meniscal tears are often seen with acute anterior cruciate ligament (ACL) injury and may be left in situ, repaired, or treated with meniscectomy. Clinical studies have shown good outcomes with vertical tears left in situ and poor outcomes following meniscectomy. However, clinically relevant studies are needed to establish a biomechanical foundation for treatment of these tea...

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...

The aims of a meniscal replacement are: 1) to reduce the pain experienced by some patients following meniscus resection; 2) to prevent the degenerative changes of cartilage and the changes in subchondral bone following meniscus resection; 3) to avoid or reduce the risk of osteoarthritis following meniscus resection; 4) to restore optimally the mechanical properties of the knee joint after menis...

This study addressed the question of whether the level of compressive load would affect the conclusions from statistical analyses aimed at determining how well a lateral meniscal autograft restores tibial contact (as indicated by the maximum contact pressure, mean pressure, and contact area) to that of the intact knee. If statistical analyses indicated that normal tibial contact was not restore...

BACKGROUND There are various indirect signs of a discoid lateral meniscus in radiographs, for example lateral joint space widening, hypoplasia of the LFC, etc. There has, however, been no previous report of the characteristic shape of the lateral femoral condyle (LFC) in patients with osteochondritis dissecans (OCD) accompanied by a discoid lateral meniscus. The purpose of this study was to eva...
