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.

Pes anserinus tendinitis/bursitis syndrome, or pes anserine bursitis, is a cause of chronic knee pain and weakness. [3] [4] It occurs when the medial portion of the knee is inflamed.
In adults, Baker's cysts usually arise from almost any form of knee arthritis (e.g., rheumatoid arthritis) or cartilage (particularly a meniscus) tear. Baker's cysts in children do not point to underlying joint disease. Baker's cysts arise between the tendons of the medial head of the gastrocnemius and the semimembranosus muscles.
Gastrocnemius muscle weakness (in standing position) Upper motor neuron lesion (for example, hemiplegia as the result of a cerebrovascular accident) Lower motor neuron lesion (for example, in post-polio syndrome) Deficit in joint proprioception; Lower limb length discrepancy; Congenital genu recurvatum; Cerebral palsy; Muscular dystrophy
A calf strain refers to damage to a muscle or its attaching tendons. [3] [4] A premature return before recovery is achieved will result in a prolonged recovery or incomplete return to baseline prior to injury. [1] Stretches such as alternating calf raises can improve flexibility as well as mobilize legs before running. [4]
The sural nerve (L4-S1) is a cutaneous sensory nerve of the posterolateral calf with cutaneous innervation to the distal one-third of the lower leg. [1] Formation of the sural nerve is the result of either anastomosis of the medial sural cutaneous nerve and the sural communicating nerve, or it may be found as a continuation of the lateral sural cutaneous nerve [2] traveling parallel to the ...
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 ...
