Tibialis Posterior Dysfunction
Pain on the inside of the ankle or arch, especially with walking or standing, may be linked to tibialis posterior dysfunction. This condition can affect foot support and stability and often becomes worse over time if left untreated.
What Is Tibialis Posterior Dysfunction?
The tibialis posterior tendon helps support the arch of the foot and control movement during walking. When it becomes irritated, weakened, or overloaded, pain can develop along the inside of the ankle and foot. Some people also notice flattening of the arch or increased fatigue in the foot and leg.
This condition is important to assess early because it can progress if the tendon continues to struggle under load. We assess the tendon, foot posture, gait, and contributing biomechanical factors so treatment can be aimed at both symptom relief and improved support.
Treatment may include gait assessment, supportive footwear advice, orthoses, targeted strengthening, and activity modification. The aim is to improve control, reduce strain, and support long-term foot function.
Common signs
- Pain along the inside of the ankle or arch
- Tired or aching feet during walking or standing
- Flattening of the arch over time
- Discomfort with prolonged activity on hard surfaces
- Difficulty standing on tiptoe on one foot
Assessment & Treatment Options
Assessment covers the tendon, foot posture, gait, and loading patterns. Treatment is aimed at reducing tendon strain and supporting better foot function over the long term.
Frequently Asked Questions
What are the early signs of tibialis posterior dysfunction?
Pain along the inside of the ankle or arch, tired feet, and discomfort with longer periods of walking are common early signs. If you notice gradual flattening of your arch, this is worth getting assessed promptly.
Can flat feet be related to this problem?
Yes. Flat or unstable foot mechanics can increase strain on the tibialis posterior tendon, and the condition can also cause the arch to lower over time if not managed.
Can orthoses help?
In many cases they can help support the foot and reduce tendon load, especially when prescribed based on a proper clinical assessment of your foot posture and gait.
