High quality MRI images (1.5 T magnet or higher [22]) of the knee can be extremely useful to diagnose injuries to the posterolateral corner and other major structures of the knee. [23] While the standard coronal , sagittal and axial films are useful, thin slice (2 mm ) coronal oblique images should also be obtained when looking for PLC injuries.
Posterior tibial tendon dysfunction is the dysfunction of the posterior tibial tendon. It is a progressive disease that has four stages [ 1 ] and is the most common cause of adult flatfoot . [ 2 ]
The tibialis posterior muscle originates on the inner posterior border of the fibula laterally. [2] It is also attached to the interosseous membrane medially, which attaches to the tibia and fibula. [2] The tendon of the tibialis posterior muscle (sometimes called the posterior tibial tendon) descends posterior to the medial malleolus. [2]
Tendinopathy is a type of tendon disorder that results in pain, swelling, and impaired function. [2] The pain is typically worse with movement. [2] It most commonly occurs around the shoulder (rotator cuff tendinitis, biceps tendinitis), elbow (tennis elbow, golfer's elbow), wrist, hip, knee (jumper's knee, popliteus tendinopathy), or ankle (Achilles tendinitis).
The medial collateral ligament (MCL), also called the superficial medial collateral ligament (sMCL) or tibial collateral ligament (TCL), [1] is one of the major ligaments of the knee. It is on the medial (inner) side of the knee joint and occurs in humans and other primates. Its primary function is to resist valgus (inward bending) forces on ...
Lateral head: lateral aspect of lateral condyle of femur Medial head: popliteal surface of femur; superior to medial condyle: Posterior surface of calcaneus via calcaneal tendon: Tibial nerve (S1, S2) Plantarflexes ankle when knee is extended; raises heel during walking; flexes leg at knee joint Plantaris
The tibial tuberosity thus forms the terminal part of the large structure that acts as a lever to extend the knee-joint and prevents the knee from collapsing when the foot strikes the ground. [1] The two ligaments, the patella, and the tibial tuberosity are all superficial, easily palpable structures. [2]
When the knee is being extended the ligament prevents the anterior horns of the menisci from moving forward, and the condylar surfaces of the femur and tibia from exerting pressure on the menisci. [2] It has a restricting effect on anterior-posterior excursion of the anterior horn of the medial meniscus at lower degrees of knee flexion. [3]
