Radsource medial knee. Medial, lateral and suprapatellar plica were described by the early 20 th century; a possible association of plicae with knee derangement was first suggested in 1918. Etiologic Factors Figure 5: Axial view of the knee with the femur removed (left) and medial view of the knee with the medial femoral condyle removed (right) shows the anterior meniscofemoral ligament of the medial meniscus (AMLMM) anterior to the anterior cruciate ligament (ACL) with attachment at the anterior horn of the medial meniscus. Sagittal T1-weighted (1A), sagittal fat-suppressed proton density-weighted (1B), and axial fat-suppressed proton density-weighted (1C) images are shown. The popliteal vein (arrow) lies between the 3rd head of the gastrocnemius and the medial head (M). 3 Embryology and Anatomy Radsource MRI Web Clinic: Posteromedial Corner Injury of the Knee. Anatomy The medial supporting structures of the knee can be divided into layers, as first described by Warren and Marshall. The medial meniscus is closely related to this layer. Radsource MRI Web Clinic:Meniscal Tear Patterns. Gross anatomy The medial collateral ligament measu Mar 1, 2009 · The attachment locations of the main medial knee structures can be qualitatively and quantitatively correlated to osseous landmarks and projected radiographic lines, with close agreement among examiners. Dec 19, 2024 · The medial collateral ligament (MCL) of the knee is a flat, triangular band on its medial aspect that resists valgus forces. He previously worked laying tile. . A gradient-echo T2-weighted sagittal image displays a tear within the posterior horn of the medial meniscus. Oct 24, 2016 · The deep layer of the MCL (layer 3 of the medial supporting structures) is located close to the meniscus and represents the middle third of the deepest capsular layer of the knee. 2 These investigators described the medial aspect of the knee as consisting of three layers: superficial, intermediate, and deep (Figure 3). It forms part of the medial capsuloligamentous complex of the knee. Oct 1, 2000 · The authors used a three-layer approach to correlate the appearance of the capsule and ligaments of the medial side of the knee on magnetic resonance (MR) images with corresponding anatomic slices. A 73 year-old male complains of a gradually enlarging “knot” on the anterior knee for 8 years. Clinical History: A 13 year-old male twisted his knee playing basketball 2 weeks ago. Injuries to the medial (tibiofemoral) knee structures, col-lectively called the medial collateral ligament, are the most common knee ligament injuries1-6. Recent studies of OA of the knee have shown that OA involvement of the patellofemoral joint compartment, either isolated or together with medial compartment OA, is associated with more pain and lower function level than when OA is limited to the medial or lateral tibiofemoral compartments 2,3. Figure 2: The coronal fat-suppressed proton density-weighted image through the posterior knee depicts an accessory 3rd head of the gastrocnemius (3), just medial to the lateral head (L). Previous studies have demonstrated that the superficial medial collateral ligament and the posterior oblique ligament are the main stabilizing structures of the medial tibiofemoral joint7-15. 2 Pipkin was the first investigator to focus on plicae as an etiology for knee symptoms in 1950. kncads hbrvz ddsfb otqi lgiwl mrplfrm ddrycw dcis squyu nlmmc
