Tibialis Posterior Tendon: Why It Matters for Runners and How to Prevent Injury

The Tibialis Posterior tendon plays a vital role in foot stability, particularly in runners and active individuals. When functioning well, it helps maintain arch support and controls foot motion. However, when injured, it can cause significant discomfort and long-term structural changes.

Anatomy and Function

The Tibialis Posterior tendon originates from the back of the tibia (shin bone) and runs down the inside of the ankle, inserting into multiple bones in the arch of the foot. Its primary functions include:

• Applying a braking force against excessive pronation – As the foot lands during walking or running, the Tibialis Posterior tendon works eccentrically to slow down the inward rolling motion, preventing excessive strain on the arch and ankle.
• Arch support and stability – The tendon maintains structural integrity by resisting excessive flattening of the foot.
• Shock absorption and propulsion – It helps transfer forces efficiently through the foot, ensuring smooth motion during push-off.

Common Causes of Injury

Runners and active individuals are particularly prone to Tibialis Posterior tendinopathy due to:

• Excessive pronation, which places excessive strain on the tendon.
• Inadequate footwear, offering insufficient support.
• Sudden increases in training intensity, leading to overload.
• Weakness in surrounding muscles, reducing the tendon’s ability to function properly.

Signs and Symptoms

Early recognition is key. Symptoms include:

• Pain along the inside of the ankle and arch, which may worsen after activity or the following day.
• Swelling or tenderness near the medial ankle.
• Weakness when pushing off while running or walking.
• A gradual flattening of the foot’s arch over time.

Treatment and Prevention

Managing Tibialis Posterior tendon issues requires a combination of biomechanical assessment and targeted interventions. Key options include:

• Gait analysis to assess foot mechanics and identify excessive pronation patterns.
• Orthotics to provide structural support and offload stress.
• Footwear advice to ensure proper support and stability.
• Shockwave therapy and laser treatment to stimulate tendon healing.
• Strengthening exercises to improve foot and ankle control.
