  • Breaststroker’s knee is the second most common swimming injury after swimmer’s shoulder.
  • It is most common in specialist breaststroke swimmers, hence the name.

The causes of breaststroker’s knee

The unnatural rotation of the knees during the breaststroke kick can put pressure on the inside of the knees.
The unnatural rotation of the knees during the breaststroke kick can put pressure on the inside of the knees.

During the propulsive phase of the breaststroke leg kick, the swimmer is required to vigorously kick backward and downwards with a ‘whipping’ action.

  • The unnatural rotation of the knees during this action can put pressure on the inside of the knees, which can result in an injury to the medial collateral ligament (MCL).
  • This can especially be the case if the leg kick is performed with poor technique.
  • Breaststroker’s knee can also occur as a result of prolonged and intense periods of kicking training.

Breaststroker’s knee symptoms

One of the most common symptoms of breaststroke knee is pain in and around the knee which may worsen during any physical exertion.

  • There may also be swelling and/or reduced mobility in the joint.

Inform your coach

As soon as the swimmer experiences any knee pain, they should inform their coach.

  • The coach should be able to re-assess the swimmer’s technique and make suggestions for any technical adjustments.
  • They may suggest a reduction in the volume of leg-kicking training.
  • At this stage, swimmers may wish to administer first aid to a swollen or painful knee by the application of an ice pack.
  • If the symptoms persist, the swimmer may be advised to rest, until the symptoms subside.
  • However, if the symptoms persist, the swimmer may be advised to seek some professional medical help, where the common course of action is the prescription of some anti-inflammatory medication.
  • Some swimmers are referred to a sports physiotherapist for treatment, which can help to reduce the pain, strengthen the surrounding muscles and speed recovery.
