Tennis leg is a painful condition of partial tearing of the medial belly of the gastrocnemius, caused by overstretching the muscle by concomitant ankle dorsiflexion and full knee extension. Contributory factors are muscle fatigue and degenerative changes. Simple conservative treatment is effective and permanent disability does not result. Prodromic calf aching has been discussed and permits preventive measures to be taken. A diagnosis of plantaris tendon rupture is erroneous.
