Kager’s Fat Pad Sprain


Kager’s fat pad sprain, also known as Kager’s triangle or Kager’s triangle syndrome, is a condition involving injury or inflammation to the retrocalcaneal bursa and adjacent structures in the ankle.

What is this Kager’s fat pad?  Kager’s fat pad is a small fatty tissue located in the space between the Achilles tendon and the calcaneus (heel bone).  The retrocalcaneal bursa is a fluid-filled sac located between the Achilles tendon and the heel bone, which helps reduce friction during ankle movement.

This typically occurs due to repetitive stress or trauma to the ankle, such as sudden dorsiflexion (bending the foot upward) or direct impact to the back of the heel.  This can lead to inflammation or swelling of the fat pad and surrounding tissues.
