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.

The medial gastrocnemius tendon arises proximal and posterior to the gastrocnemius tubercle of the medial femoral condyle. [2] This is another important landmark because it is rarely injured and attaches close to the capsular arm of the POL, thus helping the surgeon locate the femoral attachment of the POL.
the medial gastrocnemius (subtendinous) bursa between the medial head of the gastrocnemius and the joint capsule [2] the anserine bursa between the medial (tibial) collateral ligament and the pes anserinus – the conjoined tendons of the sartorius , gracilis , and semitendinosus muscles .
Posterior: done with the patient laying on stomach (prone); retract semimembranosus (one of hamstring muscles) until gastrocnemius becomes visible and continue until postero-medial capsule is visualized; Dual plate fixation: can be used over medial and lateral aspects of plateau; used for bicondylar plateau fractures.
A common injury that is normally attributed to the plantaris muscle is a condition called tennis leg. Although pain in the calf can be attributed to a rupture of the plantaris muscle, recent ultrasound research has shown that tennis leg more commonly arises from tears in the musculotendinous junction of the medial gastrocnemius. In one clinical ...
In then, the original attribution of the syndrome to the medial collateral ligament may now be outdated as many publications have suggested concomitant and even sometimes preferential involvement of the adductor magnus tendon, medial head of the gastrocnemius, or medial patellofemoral ligament. [2]
The common fibular nerve is the smaller terminal branch of the sciatic nerve. The common fibular nerve has root values of L4, L5, S1, and S2. It arises from the superior angle of the popliteal fossa and extends to the lateral angle of the popliteal fossa, along the medial border of the biceps femoris.
Weakly assists gastrocnemius in plantarflexing ankle Soleus: Posterior aspect of head and superior quarter of posterior surface of fibula; soleal line and middle third of medial border of tibia; and tendinous arch extending between the bony attachments: Plantarflexes ankle independent of position of knee; steadies leg on foot
