Tennis Leg

Tennis leg classically presents in a middle-aged person with sport-related acute pain in the middle portion of the calf, associated with a snapping sensation. Initially attributed to rupture of the plantaris tendon, more recent work has implicated rupture of the medial head of the gastrocnemius muscle at the musculotendinous junction as a more common etiology.
