Discussion of Tennis leg
- Tennis leg typically occurs in middle-aged persons, often related to an injury incurred with extension of the knee and forced dorsiflexion of the ankle.
- Although it has been described as a result of mainly sports-related activities, tennis leg also commonly results from daily activities, such as running to catch a bus or climbing stairs.
- Sudden pain is felt in the calf, and patients often report a "pop" in the calf or a feeling as though someone has kicked the back of their leg.
- The treatment of this condition is usually conservative, with elevation of the lower extremity, application of ice, and use of supportive elastic dressings.
- Descriptions of tennis leg have implicated a tear of the medial head of the gastrocnemius muscle, especially at the musculotendinous junction, as the usual pathogenesis of tennis leg
- Less frequently tennis leg results from rupture of the plantaris tendon in the medial aspect of the calf.
 Imaging Findings for Tennis leg
- US or MRI can show disruption of either the medial head of the gastrocnemius muscle or plantaris muscle.
- Fluid collection between the aponeuroses of the medial heads of the gastrocnemius and soleus muscles has been noted in cases of disruption of the medial head of the gastrocnemius muscle, as well as in cases of plantaris rupture.
- Deep vein thrombosis can mimic or complicate tennis leg.
