[2] [9] This distal attachment is the stronger of the two and makes up the floor of the pes anserine bursa. The proximal tibial attachment of the sMCL is the primary stabilizer to valgus force on the knee, whereas the distal tibial attachment is the primary stabilizer of external rotation at 30° of knee flexion. [3] [9]
The gastrocnemius muscle is prone to spasms, which are painful, involuntary contractions of the muscle that may last several minutes. [5] A severe ankle dorsiflexion force may result in a Medial Gastrocnemius Strain (MGS) injury of the muscle, commonly referred to as a "torn" or "strained" calf muscle, which is acutely painful and disabling.

Sometimes, the SSV joins the common gastrocnemius vein before draining in the popliteal vein. [2] Sometimes, it does not make contact with the popliteal vein, but goes up to drain in the GSV at a variable level. [1] Instead of draining in the popliteal vein, it can merge with the Giacomini vein and drain in the GSV at the superior 1/3 of the thigh.
Posteriorly: The popliteal vein and the tibial nerve, fascia, and skin. Laterally: The biceps femoris and the lateral condyle of femur in upper part, and plantaris, lateral gastrocnemius in lower part. Medially: The semimembranosus and the medial condyle of femur in upper part, and tibial nerve, popliteal vein, medial head of gastrocnemius in ...
The popliteal artery courses more medially around a normally positioned medial head of the gastrocnemius muscle. [3] Type II The medial head of the gastrocnemius muscle attaches more laterally to the femur. [3] Type III Aberrant additional tendon of the gastrocnemius muscle encircles a normally positioned popliteal artery. [3] Type IV
Along the side of the muscle, and superficial to it, is the small saphenous vein. The sural nerve accompanies the small saphenous vein as it descends in the posterior leg, traveling inferolateral to it as it crosses the lateral border of the Achilles tendon. [12] The tendon is the thickest tendon in the human body. [11]

The plantaris closely follows the lateral head of the gastrocnemius. Its tendon runs between those of the soleus and gastrocnemius and is embedded in the medial end of the calcaneus tendon. [32] In the deep layer, the tibialis posterior has its origin on the interosseus membrane and the neighbouring bone areas and runs down behind the medial ...
