Popliteus tendinopathy causes lateral knee pain. During the examination, patients present tenderness at the lateral epicondyle of the femur, along the popliteus, and at its insertion. Patients also present swelling and redness. There must also be attention for asymmetry, erythema of the involved tendon, change in range of motion
3 lut 2022 · Popliteus tendinitis, also known as popliteus tendonitis or tenosynovitis, is a rare cause of pain in the back and outside of the knee. Generally, this condition is poorly understood and misdiagnosed as other problems, such as ligament or cartilage injuries.
15 cze 2024 · The most important role of the popliteus is to provide advancing stabilization of the knee and the stabilization of the lateral meniscus during knee flexion. It is considered as a flexion starter as it allows the knee to be flexed from full extension. Due to this function, the popliteus muscle is often seen as the key to unlock the knee [ , ].
The popliteus muscle has both static and dynamic function at the knee joint. Dynamic functions: During initial flexion of the knee, it initiates and maintains the internal rotation of the tibia on the femur (unlocking of knee joint) and prevents forward dislocation of the femur on the tibia.
Popliteus Tendinitis: Biomechanical Factors and Conservative Treatment. Thomas Michaud, DC. The popliteus muscle originates from the lateral aspect of the distal femur and inserts along the posterior aspect of the proximal tibia.
Different EMG studies have shown that popliteus muscle activity increases with knee extension and downhill walking, thereby consolidating its role in the control of hyperextension of the knee joint. The referred pain pattern in case of trigger point of popliteus muscle is back of knee.
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.
