30 paź 2023 · The popliteus muscle plays an important role in the gait cycle by initiating the flexion of the fully extended (“locked”) knee. Thus, the popliteus is referred to as the “key to unlock the knee”. In addition, the popliteus muscle is the main stabilizer of the posterior knee region.

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.
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...
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.
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. It inserts onto the proximal tibia, immediately above the origin of the soleus muscle.
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.
Popliteus muscle is innervated by a branch of Tibial Nerve which is also a content of the popliteal fossa. FUNCTION. Internally rotates the Tibia relative to the Femur and unlock the knee joint during initiation of the Knee flexion.
