Posterior Tibial Tendinopathy

One of the main muscles located at the back of the leg is called the Tibialis Posterior muscle. The main function of this muscle is to be able to hold the arch and support the foot during gait. Tendinopathy of this muscle is said to occur when it gets inflamed, torn or ruptured. Thus, the functional ability reduces causing a reduction in stability and support at the arch of the foot – causing flat foot.

Posterior Tibialistendinopathy


  • Acute injury such as falls or trauma
  • Overuse from sporting activities


  • Pain at the arch of the foot
  • Pain increases with activity
  • Some pain may be felt at the outer aspect of the heel when there is heel contact
  • Swelling may or may not be present
  • Slight collapse of the arch (may be over time)

The severity of the condition can be determined with the aid of diagnostic imaging such as X-rays or Ultrasounds.

Treatment plans will vary depending on the severity of the condition. It may range from active rest to the use of orthoses to offload and redistribute the pressure from the tendon, or possible surgery if there is a complete tear of the tendon.
