Disease relevance of Menisci, Tibial

• The analysis focused on the six most common diagnoses: anterior cruciate ligament tear, lateral meniscal tear, medial meniscal tear, osteochondritis dissecans, discoid lateral meniscus, and osteochondral fracture [1].
• Recent reports indicate that combined anterior cruciate ligament/medial collateral ligament (ACL/MCL) knee injuries are usually associated with a lateral meniscus tear [2].

High impact information on Menisci, Tibial

• Discoid medial meniscus [3].
• In addition, dermatan sulfate levels increased significantly in the middle and outer zones of the lateral menisci compared with the same zones of the meniscus from the saline-treated group [4].
• There was 0.20 +/- 0.01 and 0.25 +/- 0.04 microg PRG4/cm(2) area of lateral and medial meniscus surface, respectively [5].
• This difference in translation patterns indicates that the posterior horn of the medial meniscus might encounter shear, potentially explaining the high rate of secondary medial meniscal tears in patients with ACL-deficiency [6].
• Meniscal protrusion is more frequently present in the medial meniscus and averaged less than 3 millimeters in normal volunteers in either the sagittal or coronal MR imaging plane [7].

Biological context of Menisci, Tibial

• A popular model to study OA is the knee joint of sheep following medial or lateral meniscus removal combined with exercise, but there is a need for an estrogen-deficient large animal model of OA to study articular cartilage changes occurring after menopause [8].
• Road traffic accident victims had a higher incidence of PCL and lateral meniscus injuries than did a series of athletes with injuries [9].

Anatomical context of Menisci, Tibial

• Our patient presented with a rare lesion, a patella osteogenic sarcoma that spread to the anterior horn of the lateral meniscus via the arthroscope [10].
• Bilateral discoid medial menisci: association with bone changes in the tibia [11].
• We reviewed the sagittal and coronal magnetic resonance images of 173 knees for lateral meniscus tears and the presence of the meniscofemoral ligaments [12].
• There was a trend towards better healing of isolated meniscus repairs and lateral meniscus tears less than eight weeks old associated with ACL reconstruction when a blood clot injection was used to supplement the rasp abrasion of the parameniscal synovium [13].

Associations of Menisci, Tibial with chemical compounds

• A porous polyurethane prosthesis was used to replace the lateral meniscus in the dog [14].
• Three tantalum beads were inserted in the medial meniscus of six human-cadaver joints [15].
• The medial menisci of both knees in 32 Iceland sheep were operated on with either sham operation (C6), medial meniscectomy (M6), primary transplantation (P6), or secondary transplantation 3 months after meniscectomy (S6) [16].
• The purpose of this research was to quantify the mechanical properties of both fresh and glutaraldehyde-cross-linked canine medial menisci [17].
• The femoral faces of medial and lateral menisci of the rabbit knee were structurally reinforced with tannic acid and studied using the scanning electron microscope [18].

Gene context of Menisci, Tibial

• In general, the increase in COL1A1 and COL6A3 mRNA concentrations was greater in medial menisci than in lateral menisci [19].
• Even chondral fractures of the lateral femoral condyle outnumbered medial meniscus tears [6 (17%) versus 4 (11%)] in patients with a second-degree MCL sprain [20].
• In reconstructing the ACL, ideal tibial tunnel placement requires an understanding of the unique anatomy of the ACL tibial footprint and its relationship to the PCL, lateral meniscus, and medial tibial part of the spine [21].
• Pathologic examination of the resected specimen showed osteogenic sarcoma of the patella and a completely separate 1.0-cm nodule of osteogenic sarcoma tissue growing in the anterior horn of the lateral meniscus [10].
• The anterior horn of the lateral meniscus moves 6.3 mm, and the posterior horn 4.0 mm, with 3.4 mm of radial displacement [22].

Analytical, diagnostic and therapeutic context of Menisci, Tibial

• We have seen twelve patients with the so-called complete type of discoid lateral meniscus, with intact ligament attachments as an incidental finding at the time of arthroscopy [23].
• Arthrography of the discoid lateral meniscus [24].
• In a retrospective study, 14,731 menisci were examined to determine the incidence of discoid medial and lateral menisci [25].
• We concluded that arthroscopic partial meniscectomy should be the preferred method for the surgical treatment for discoid lateral menisci, due to it's minimal traumatic effects, possibilities of early mobilization, a lower complication rate, and easy and short rehabilitation period [26].
