Calf muscle tear
Rupture of the gastrocnemius muscle

A calf muscle tear is the result of a (partial) rupture of the gastrocnemius (calf) muscle. The tear is the result of a sudden, powerful contraction of the muscle against high resistance.

Description of the condition

The muscle that defines the calf is called the gastrocnemius muscle. A calf muscle tear occurs during contraction of the muscle. Usually the tear is located along the inner (medial) part of the gastrocnemius, at the site of the muscle-tendon transition.

Cause and origin

In general, a calf muscle tear will occur during exercise. A classic example is that the patient will feel as if a small stone or twig hit the calf during exercise. This is the moment that the muscle tear occurred.

Signs & symptoms

  • A sharp pain is felt in the calf immediately after the injury.
  • The patient is usually unable to walk any further because of the pain.
  • Standing on the toes of the affected leg is painful.
  • Stretching the calf muscle is painful.
  • The calf can be slightly swollen.
  • The muscle tear is sensitive to touch.
  • In the days after the injury, a bruise (haematoma) can be visible under the skin where the tear occurred.



It is important to keep the weight of the muscle in the first days to a week after the injury. This can then be followed by light weight-bearing on the muscle under the supervision of the physiotherapist. Using an exercise programme to increase strength and mobility, the muscle is then trained until the sports activity can be resumed. Recovery takes approximately 6 to 10 weeks. It is irresponsible to resume sports activities before this time and without gradually increasing the training load.


Training the muscle must be done very carefully. That is why you will find here a carefully constructed programme of exercises with exercises for whiplash in your calf.

You can check your symptoms using the online physiotherapy check or make an appointment with a physiotherapy practice in your area.
