Posterior tibial tendon dysfunction (PTTD) is a condition that affects the tendon running along the inside of the ankle. It often begins with mild discomfort but can gradually lead to arch collapse and flatfoot changes if not properly treated.
Early assessment is important to prevent progression.
Our foot clinic provides professional posterior tibial tendon dysfunction treatment in Toronto focused on reducing pain and preserving foot structure.
The posterior tibial tendon helps support the arch of the foot and stabilize the ankle during walking.
Posterior tibial tendon dysfunction occurs when this tendon becomes irritated, weakened, or partially torn. As the tendon loses strength, the arch may gradually flatten and the foot may roll inward more than normal.
Without intervention, symptoms can progress over time.
Common contributing factors include:
Flat feet or overpronation
Repetitive strain from walking or standing
Previous ankle injury
Sudden increase in activity
Aging-related tendon changes
Inflammatory conditions
The condition often develops gradually rather than from a single traumatic event.
You may notice:
Pain along the inside of the ankle or arch
Swelling near the inner ankle bone
Gradual flattening of the arch
Foot turning outward when standing
Difficulty standing on your toes
Increased fatigue when walking
Symptoms may worsen with prolonged activity.
Treatment focuses on supporting the tendon and reducing strain.
Biomechanical assessment helps evaluate arch stability, foot alignment, and walking patterns.
Custom orthotics may be recommended to provide arch support and reduce stress on the posterior tibial tendon.
Immobilization or bracing may be considered in certain cases to allow the tendon to rest and recover.
Stretching and strengthening guidance may be provided to improve tendon function and calf flexibility.
Shockwave therapy may be considered for persistent tendon irritation to stimulate healing.
Treatment plans are individualized depending on severity and structural changes.
Consider booking an assessment if:
Inner ankle pain continues for several weeks
The arch appears to be flattening
Walking becomes uncomfortable
Swelling persists
You notice progressive changes in foot alignment
Early intervention can help prevent long-term structural changes.
If you are experiencing pain along the inside of your ankle or notice changes in your arch, a professional assessment can help determine the cause and guide appropriate treatment.
