3 sty 2022 · 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. Internally rotates tibia relative to femur and unlocks knee during knee flexion initiation. Innervation.
28 sie 2024 · The popliteus is a muscle within the deep compartment of the posterior leg. It lies behind the knee joint, forming the base of the popliteal fossa. Attachments: Originates from the lateral condyle of the femur and the lateral meniscus of the knee joint.
5 cze 2023 · Structure and Function. The muscle fibers of the popliteus originate from the lateral condyle of the femur and insert on the posterior surface of the tibia, superior to the soleal line.
The popliteus appears to act as a dynamic guidance system for monitoring and controlling subtle transverse- and frontal-plane knee joint movements, controlling anterior-posterior lateral meniscus movement, unlocking and internally rotating the knee joint (tibia) during flexion initiation, assisting with 3-dimensional dynamic lower extremity post...
Unlocking the Knee Joint (Primary Function): The primary function of the popliteus muscle is to "unlock" the knee joint from a fully extended position (as in standing) to a flexed position (as in bending the knee). When the knee is fully extended, the femur tends to rotate laterally on the tibia.
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.
