Gastrocnemius refers to the gastrocnemius muscle, which is located on the posterior side of the knee and calf, and its medial and lateral heads originate from behind the medial and lateral epicondyles of the femur. When the muscle is contracted, it will drive the knee joint into flexion, and when the gastrocnemius muscle is torn, it will affect the function of the knee joint in flexion.
The gastrocnemius muscle is an important part of the posterior calf muscle, which is superficial, and together with the deeper flounder muscle, it continues down to the Achilles tendon and ends at the Achilles tuberosity. The contraction of the gastrocnemius muscle leads to flexion of the knee as well as flexion of the ankle. When the gastrocnemius muscle is completely ruptured, knee motion is severely compromised.
In case of a complete rupture of the gastrocnemius muscle, it is important to go to the hospital in time for medical consultation and treatment, and timely surgical repair, so as not to affect the function of the limb.
