The popliteus muscle can produce two types of actions; lateral rotation of the femur or medial rotation of the tibia. These actions are dictated by the phase of the gait cycle: During the closed chain phase of the gait cycle, the foot is in contact with the ground The popliteus assists in flexing the leg upon the thigh; when the leg is flexed, it will rotate the tibia inward. It is especially called into action at the beginning of the act of bending the knee, in as much as it produces the slight inward rotation of the tibia, which is essential in the early stage of this movement The popliteus muscle assists in knee flexion and its function is decided according to the position of the lower extremity, i.e. weight-bearing or non weight-bearing, as it is a primary internal rotator of the tibia in a non weight-bearing position. In open chain kinematics, it rotates tibia mediall The popliteus muscle is innervated by the tibial nerve. The popliteus muscle unlocks the knees by laterally rotating the femur on the tibia when the foot is in contact with the ground. When the leg is not in contact with the ground, the popliteus medially rotates the tibia on the femur The main functions of the popliteus are flexion and internal rotation of the knee
Due to its location and muscle action, the popliteus is a big player in the healthy functioning of the knee joint. Injury to the popliteus muscle may arise in a weight-bearing position with a varus force to the knee whilst the tibia is externally rotated, or a forced hyperextension moment with the tibia internally rotated 1 The Popliteus Muscle is one of the deep flexors of the knee.

Get your copy on http://www.practicalguidestohealing.co Action: Medial rotation and flexion of knee . Description: The Popliteus is a thin, flat, triangular muscle, which forms the lower part of the floor of the popliteal fossa. It arises by a strong tendon about 2.5 cm. long,. Muskelns funktion är att vrida underbenet i förhållande till låret. Popliteus är särskilt viktig när knäböjning ska påbörjas från rakt läge; den vridning som popliteus åstadkommer är nödvändig för att låsa upp knäleden. Muskeln innerveras av nervus tibialis
The popliteus muscle was studied during both normal gait and a series of planned exercises. Its activity during the walking cycle was shown to begin shortly before heel-strike and to continue throughout three-quarters of the stance phase. During the exercises the muscle was active during internal ro Popliteus Biomechanics Action: Medial rotation of the tibia; lateral rotation of the femur, flexion of the knee joint Unlocks the knee with open or closed chain activities External Rotation of Femur - Closed Chain Internal Rotation of Tibia - Open Chai Action: Popliteus is responsible for flexing the TF joint, and also causes rotation of the TF joint when flexed*. Innervation: The popliteus is innervated by the tibial nerve, which is a branch of the sciatic nerve that innervates the muscles of the lower leg Popliteus. Origin: Anterior part of the popliteal groove on lateral surface of lateral femoral condyle. Insertion: Posterior surface of tibia in a fan-like fashion, just superior to the popliteal line. Action: Rotates knee medially and flexes the leg on the thigh Popliteus is a triangular shaped muscle that is found deep in the popliteal fossa at the back of the knee, just below the joint. Location. Popliteus arises from the outer surface of the lateral femoral condyle, from within the joint capsule, below the lateral epicondyle and the superior attachment of the lateral collateral ligament. The stout tendon passes backwards, downwards and medially.
Popliteus. The popliteus muscle is a band of muscular tissue located in the leg. The muscle wraps around the bottom half of the femur, or thighbone. It inserts on the back of the shinbone, or. Function. The popliteus assists in flexing the leg upon the thigh; when the leg is flexed, it will rotate the tibia inward.. It is especially called into action at the beginning of the act of bending the knee, in as much as it produces the slight inward rotation of the tibia, which is essential in the early stage of this movement.. When the knee is in full extension, the femur slightly. The popliteus muscle is a band of muscular tissue located in the leg.

Popliteus Muscle: Definition. The popliteus muscle is a thin, flat, triangular-shaped muscle located at the back of the knee joint. This muscle gets its name from the word popliteal, which is an. The popliteus attaches proximally onto the lateral surface of the lateral condyle of the femur. ACTIONS: Medially rotates the leg at the knee joint. Laterally rotates the thigh at the knee joint. Flexes the leg at the knee joint. NOTES: The proximal tendon of the popliteus travels through the knee joint cavity The posterior aspect of forty cadaver knees was dissected to determine the proximal insertion of the popliteus tendon, particularly its relationship to the lateral meniscus. Thirty-three (82.5 per cent) of the specimens demonstrated no major attachment of the popliteus tendon to the lateral meniscus
Which is an action of the popliteus? A)lateral rotation of the leg at the knee joint B)lateral rotation of the thigh at the hip joint C)medial rotation of the leg at the knee joint D)medial rotation of the thigh at the hip join Popliteus is a minor flexor of the knee, and it can also produce medial rotation of the tibia. Lying on top of popliteus is the small plantaris muscle. It which we'll see in the next section, to form the calcaneal tendon, or heel cord. Gastrocnemius has a slight flexing action at the knee, but its main action, by far, is at the. The Popliteus comes into action especially at the commencement of the movement of flexion of the knee; by its contraction the leg is rotated inward, or, if the tibia be fixed, the thigh is rotated outward, and the knee-joint is unlocked Popliteus Tendinitis. Popliteus tendinitis is often caused by a tendon strain. There are 3 levels of strains to the popliteus tendon. Level 1 - The strain in the popliteus tendon causes pain but the tendon is not lengthened. Level 2 - The strain in the popliteus tendon is lengthened because the ligament is stretched or ruptured

A popliteus strain is when the muscle fibres tear due to too much force being applied to the muscle. There are three categories a popliteus strain can be decribed as. Grade two - extensive damage with more than 5% of the muscle fibres involved. Grade three - complete rupture of the popliteus muscle Tensor fasciae latae muscle (Musculus tensor fasciae latae) Tensor fasciae latae is a fusiform muscle located in the lateral aspect of the thigh.It belongs to the muscles of the gluteal region, along with the gluteus maximus, gluteus medius and gluteus minimus muscles.. Tensor fasciae latae is found superficial in the anterolateral aspect of the thigh, spanning from the anterior portion of the. Popliteus facilitates bending of the knee, by generating a slight rotation inward of the tibia. On the other hand, Popliteus locks the joint in place by slightly rotating the femur on the tibia. Often, people refer to popliteus as key owing to its strange twisting action on the femur. Control for this muscle comes from the tibial nerve from. popliteus muscle A short diagonally placed muscle running from the outer side of the lower end of the thigh bone (femur) to the back of the upper part of the main lower leg bone (TIBIA).

Plantaris Muscle Injuries. Fig. 20.1. Schematic drawing of the posterior view of the lower leg illustrates the plantaris muscle. The long tendon is commonly harvested by orthopedic surgeons as an autograft for ligament and tendon reconstructions, demonstrating that function is maintained despite the absence of the tendon [ 7 ] Popliteal tendinopathy / tendinitis refers to an overuse injury of the popliteal tendon. The condition is also known as popliteus syndrome. The popliteus is a small muscle which is located at the back of your knee. It is important in unlocking the knee from a fully straightened position Abstract Background The popliteus tendon (PT) or lateral collateral ligament (LCL) stabilizes the postero-lateral aspects of the knees. When surgeons perform total knee arthroplasty (TKA), PT and LCL iatrogenic injuries are a risk because the femoral attachments are relatively close to the femoral bone resection area 1.
