When this bulge becomes large enough, it becomes palpable and cystic. Most Baker's cysts maintain this direct communication with the synovial cavity of the knee, but sometimes, the new cyst pinches off. A Baker's cyst can rupture and produce acute pain behind the knee and in the calf and swelling of the calf muscles.
Moving from superficial to deep structures, the roof is formed by: the skin. [1]the superficial fascia. [1] This contains the small saphenous vein, the terminal branch of the posterior cutaneous nerve of the thigh, posterior division of the medial cutaneous nerve, lateral sural cutaneous nerve, and medial sural cutaneous nerve.
Another is between the popliteal artery and the posterior surface of the knee-joint. It receives afferents from the knee-joint, together with those that accompany the genicular arteries. The others lie at the sides of the popliteal vessels, and receive, as efferents, the trunks that accompany the anterior and posterior tibial vessels. [2]
There is sometimes an additional head from the sesamoid bone in the lateral (outer) head of the gastrocnemius muscle. Rarely an additional inconstant muscle; the popliteus minor is seen. It originates from the femur on the inner side of the plantaris muscle and inserts into the posterior ligament of the knee-joint. Peroneotibialis, 14% of ...
The plantaris muscle and a portion of its tendon run between the two muscles, which is involved in "locking" the knee from the standing position. Since the anterior compartment of the leg is lateral to the tibia, the bulge of muscle medial to the tibia on the anterior side is actually the posterior compartment. The soleus is superficial to the ...
The popliteus tendon's main attachment is on the femur at the proximal portion of the popliteus sulcus. As the tendon runs posteriorly and distally behind the knee, it gives off 3 fascicles that attach to and stabilize the lateral meniscus. The popliteus tendon provides static and dynamic stabilization to the knee during posterolateral rotation.
Iliotibial band syndrome is one of the leading causes of lateral knee pain in runners. The iliotibial band is a thick band of fascia composing the tendon of the tensor fasciae latae muscle. It is located on the lateral aspect of the knee, extending from the outside of the pelvis, over the hip and knee, and inserting just below the knee. The ...
All four parts of the quadriceps muscle attach to the patella (knee cap) by the quadriceps tendon. The rectus femoris is situated in the middle of the front of the thigh ; it is fusiform in shape, and its superficial fibers are arranged in a bipenniform manner, the deep fibers running straight ( Latin : rectus ) down to the deep aponeurosis .
