Pain on the Inside of the Ankle and Foot (Medial Side)

Tendonitis is a common foot problem as our feet take tremendous amounts of stress and rarely get to rest. The Posterior Tibial Tendon is particularly prone to problems as it must work constantly to support the arch of the foot.

If you think you may have posterior tibial tendonitis make an appointment right away to see us in our Seattle clinic. If not treated, this tendonitis can lead to a rupture or tear of the tendon.

Anatomy – Why is the Posterior Tibialis Tendon Prone to Injury?

posterior tibial tendonitis

Figure 1 – Posterior Tibial Tendon

The posterior tibial tendon starts deep in the calf and runs behind the ankle bone on the inside of the ankle. The tendon continues along towards the foot and attaches into multiple locations on the inside of the foot and the bottom of the arch. A tremendous amount of tension and stress is placed is on this tendon with every step as it helps to maintain and recreate the arch of the foot. The amount of stress on the tendon varies from person to person depending on the shape of their foot (flatfeet versus a very high arch). It would seem that only a flatfooted person would get posterior tibial tendonitis is more common in flatfooted people, but it can occur in anyone.

Symptoms of Posterior Tibial Tendonitis – Pain on the Inside of the Foot

Symptoms of posterior tibial tendonitis include pain and swelling along the inside of the ankle and arch along the course of the tendon. There is often pain on the inside of the of foot. Pain is present with walking, exercise or just standing. This discomfort will usually increase over time. This pain initially is absent when at rest but may progress to the point where pain is present even when not active. In advanced cases the injury to the tendon that started as tendonitis may result in a full or partial tear of the tendon.

Diagnosing Posterior Tibial Tendonitis

We can usually make this diagnosis very easily by history and examination. Sometimes we will order an MRI or ultrasound to determine the extent of damage to the posterior tibial tendon.

Initial Treatment

Treatment can depend on how long the symptoms have been present and the amount of strength that is lost (if any) in the tendon. Initial treatment may include:

  • Anti-inflammatory medication
  • Taping or ankle braces
  • Use of a walking boot
  • Orthotics
  • Physical therapy,
  • Rest

Orthotics for Posterior Tibial Tendonitis

Orthotics for this problem are designed specifically to reduce tension on the posterior tibial tendon. This often requires an orthotic that is deeper than normal around the heel and perfectly matches the arch of the foot (total contact orthotics). The correct orthotic can not only help heal the tendon by reducing tension on it but can also help prevent reoccurrence of the problem.

Treatment for Resistant Cases

This problem should be treated as early as possible in order to prevent damage to the tendon that can be more difficult to treat. Call us at our Seattle clinic right away if you are having symptoms.

In more severe cases a cast or walking boot from the knee down may be utilized from four to six weeks to allow the tendon to completely rest without placing the day-to-day demands of walking on it. An arch support or orthotic must be worn in the boot to support the arch and further reduce tension on the posterior tibial tendon. If these measures fail to produce acceptable results surgical intervention may be necessary to clean around the tendon and repair any defects in the tendon. Surgical repair is more commonly needed when there is a progressive weakness in the tendon. This loss of strength is called posterior tibial tendon dysfunction.

Taping for Posterior Tibial Tendonitis – Video

We often have our patients use special taping techniques to reduce tension on the posterior tibial tendon.  We recommend the use of kinesiology tape since it does not irritate the skin as standard athletic tape often does.  The video below shows proper technique for applying tape to protect the tendon.

Self Treatment Suggestions for Posterior Tibial Tendonitis and Pain on the Inside of the Ankle and Foot

Posterior tibial tendonitis and other causes of pain on the inside of the ankle and can sometimes be difficult to treat, so we do think you should see a podiatrist with a specialty in biomechanics. If you want to try home treatment first, use the following suggestions. If you are not better in 3 weeks, see a medical professional.

Keep in mind that treatment is focused on taking tension off of the posterior tibial tendon by supporting the arch of the foot. We recommend never going barefoot during this three week period of treatment. The following items are affiliate links and we will receive a small commission on items purchased.

Use an arch support in your shoes

An arch support, particularly one that conforms close to the arch of your foot, will act to support the arch and reduce tension on the posterior tibialis tendon. OTC arch supports will not work as wp3ell as a quality custom orthotic, but will help. The best ones have a high enough arch to do a good job supporting the arch of the foot. In addition they are firm enough to not collapse under the arch of the foot. The best we have found for inside of ankle pain to fit in athletic and walking shoes is the FootChair Podiatrist Designed Orthotic. It is the only OTC arch support we have found with both an exceptional arch and additional pads that can be used to increase the arch height.

For use in smaller shoes including high heels, flats, soccer cleats FootChair makes a much smaller orthotic that still has the adjustable height arch support. This is the FootChair Slim Orthotic. We also like it because it flexes to fit different heel heights

flip flopsUse a sandal or slipper with an arch support to wear around the house. This will act to support your arch when you are not wearing shoes. We recommend the Vionic Arch Support Sandals and Slippers for their superior arch support.

pttd braceWear an ankle brace designed to take tension off of the posterior tibial tendon.  For the first few pttd aircasetweeks of treatment it can help tremendously to take more tension off of the tendon than an arch support can do. If you cannot get custom orthotics right away, the AirCast Posterior Tibial Tendon Ankle Brace is made especially for the treatment of problems affecting the posterior tibial tendon. It has two air bladders that lie along the inside of the arch and the inside of the ankle. These air bladders can be pumped up in order  to take maximum tension off of the posterior  tibialis tendon.

orthaheel walker shoeUse shoes with excellent support features. You can find a list of Seattle area shoe stores on our Shoe List. If you don’t have a good shoe store nearby, these Orthofeet Shoes for Women and Orthofeet Shoes for Men provide great support for flat feet.

For more severe pain or longer lasting problems, wear a walking boot until you can see a medical professional. We recommend a high walking bootperoneal tendonitis self treatment ossur brace tall boot because they do a better job at decreasing tension on the posterior tibialis. Be sure to wear an arch support in the boot. Without the arch support your foot can collapse in the boot which increases tension on the injured tendon.

Above all, don’t go barefoot at all for the first few weeks. Wear the ankle brace, walking boot, stable shoes with the orthotics or at least the sandals with arch support at all times when you are bearing weight. Usually the more support you have the fast you will heal, so the ankle brace or the boot should be worn for the first week or two and then transition into the shoes and arch supports.

Ice the inside of your ankle and foot two – three times per day for 10 minutes each time.

If you are not getting better or are not completely better within a few weeks, see a medical professional.
