Posterior Tibial Tendon Dysfunction (PTTD)
Overview
Originally known as posterior tibial tendon dysfunction or insufficiency, adult-acquired flatfoot deformity encompasses a wide range of deformities. These deformities vary in location, severity, and rate of progression. Establishing a diagnosis as early as possible is one of the most important factors in treatment. Prompt early, aggressive nonsurgical management is important. A patient in whom such treatment fails should strongly consider surgical correction to avoid worsening of the deformity. In all four stages of deformity, the goal of surgery is to achieve proper alignment and maintain as much flexibility as possible in the foot and ankle complex. However, controversy remains as to how to manage flexible deformities, especially those that are severe. 
Causes
There are a number of theories as to why the tendon becomes inflamed and stops working. It may be related to the poor blood supply within the tendon. Increasing age, inflammatory arthritis, diabetes and obesity have been found to be causes.
Symptoms
The first stage represents inflammation and symptoms originating from an irritated posterior tibial tendon, which is still functional. Stage two is characterized by a change in the alignment of the foot noted on observation while standing (see above photos). The deformity is supple meaning the foot is freely movable and a ?normal? position can be restored by the examiner. Stage two is also associated with the inability to perform a single-leg heel rise. The third stage is dysfunction of the posterior tibial tendon is a flatfoot deformity that becomes stiff because of arthritis. Prolonged deformity causes irritation to the involved joints resulting in arthritis. The fourth phase is a flatfoot deformity either supple (stage two) or stiff (stage 3) with involvement of the ankle joint. This occurs when the deltoid ligament, the major supporting structure on the inside of the ankle, fails to provide support. The ankle becomes unstable and will demonstrate a tilted appearance on X-ray. Failure of the deltoid ligament results from an inward displacement of the weight bearing forces. When prolonged, this change can lead to ankle arthritis. The vast majority of patients with acquired adult flatfoot deformity are stage 2 by the time they seek treatment from a physician.
Diagnosis
Examination by your foot and ankle specialist can confirm the diagnosis for most patients. An ultrasound exam performed in the office setting can evaluate the status of the posterior tibial tendon, the tendon which is primarily responsible for supporting the arch structure of the foot.
Non surgical Treatment
Because of the progressive nature of PTTD, early treatment is critical. If treated soon enough, symptoms may resolve without the need for surgery and progression of the condition can be stopped. If left untreated, PTTD may create an extremely flat foot, painful arthritis in the foot and ankle, and will limit your ability to walk, run, and other activities. Your podiatrist may recommend one or more of these non-surgical treatments to manage your PTTD. Orthotic devices or bracing. To give your arch the support it needs, your foot and ankle surgeon may recommend an ankle brace or a custom orthotic device that fits into your shoe to support the arch. Immobilization. A short-leg cast or boot may be worn to immobilize the foot and allow the tendon to heal. Physical therapy. Ultrasound therapy and stretching exercises may help rehabilitate the tendon and muscle following immobilization. Medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce the pain and inflammation. Shoe modifications. Your foot and ankle surgeon may recommend changes in your footwear. 
Surgical Treatment
For those patients with PTTD that have severe deformity or have not improved with conservative treatments, surgery may be necessary to return them to daily activity. Surgery for PTTD may include repair of the diseased tendon and possible tendon transfer to a nearby healthy tendon, surgery on the surrounding bones or joints to prevent biomechanical abnormalities that may be a contributing factor or both.
Does Pain In The Arches Require Surgical Procedures ?
Overview
Plantar Fasciitis is a common condition that involves degenerative changes (wear and tear) of the thick fibrous band of tissue that runs from the heel bone beneath the arches through to the ball of the foot. Plantar Fasciitis can be caused by a range of factors including: high impact exercises, excessive body weight, hormonal changes and/or foot biomechanics (foot alignment with weight bearing including high arches or flat feet).
Causes
There are many different causes of flat feet, which can be separated into two main categories. The first category, congenital flat foot, is a condition that one is born with or is predisposed to at birth. This type includes the completely asymptomatic, pediatric flexible flat foot-by far the most common form of congenital flat foot. Flexible means that an arch is present until weight is put on the foot, at which time the arch disappears. This foot type is a result of the fact that all people are born with different physical features. Some people have bigger noses than others, just as some people have flatter feet (of course, there is no known correlation between the two). Any alteration in the many building blocks of the foot can influence its shape.
Symptoms
Symptoms of plantar fasciitis may occur anywhere along the arch, but it is most common near its attachment to the heel bone. Symptoms of plantar fasciitis vary, but the classic symptom is pain after rest--when you first get out of bed in the morning, or when you get up after sitting down for a while during the day. This is known as "post-static dyskinesia." The pain usually diminishes after a few minutes of walking, sometimes even disappearing, but the pain is commonly felt again the longer you're on the foot. Fasciitis can be aggravated by shoes that lack appropriate support, especially in the arch area, and by the chronic irritation of long-periods of standing, especially on concrete, and by being overweight. Other factors which influence this condition are gender (females get this more than men), age (30s to 50s are most common), and those with flatter-than-normal feet. It doesn't help that fascia doesn't heal particularly quickly. This is because it has relatively poor circulation, which is why it's white in colour.
Diagnosis
Magnetic Resonance Imaging (MRI) can show tendon injury and inflammation but cannot be relied on with 100% accuracy and confidence. The technique and skill of the radiologist in properly positioning the foot with the MRI beam are critical in demonstrating the sometimes obscure findings of tendon injury around the ankle. Magnetic Resonance Imaging (MRI) is expensive and is not necessary in most cases to diagnose posterior tibial tendon injury. Ultrasound has also been used in some cases to diagnose tendon injury, but this test again is usually not required to make the initial diagnosis.
Non Surgical Treatment
Cortisone, a type of steroid, is a powerful anti-inflammatory medication. It can be injected into the plantar fascia to reduce inflammation and pain. Your doctor may limit your injections. Multiple steroid injections can cause the plantar fascia to rupture (tear), which can lead to a flat foot and chronic pain. Supportive shoes and orthotics. Shoes with thick soles and extra cushioning can reduce pain with standing and walking. As you step and your heel strikes the ground, a significant amount of tension is placed on the fascia, which causes microtrauma (tiny tears in the tissue). A cushioned shoe or insert reduces this tension and the microtrauma that occurs with every step. Soft silicone heel pads are inexpensive and work by elevating and cushioning your heel. Pre-made or custom orthotics (shoe inserts) are also helpful. Most people sleep with their feet pointed down. This relaxes the plantar fascia and is one of the reasons for morning heel pain. A night splint stretches the plantar fascia while you sleep. Although it can be difficult to sleep with, a night splint is very effective and does not have to be used once the pain is gone. Your doctor may suggest that you work with a physical therapist on an exercise program that focuses on stretching your calf muscles and plantar fascia. In addition to exercises like the ones mentioned above, a physical therapy program may involve specialized ice treatments, massage, and medication to decrease inflammation around the plantar fascia. Extracorporeal shockwave therapy (ESWT). During this procedure, high-energy shockwave impulses stimulate the healing process in damaged plantar fascia tissue. ESWT has not shown consistent results and, therefore, is not commonly performed. ESWT is noninvasive-it does not require a surgical incision. Because of the minimal risk involved, ESWT is sometimes tried before surgery is considered.
Surgical Treatment
Surgery is considered only after 12 months of aggressive nonsurgical treatment. Gastrocnemius recession. This is a surgical lengthening of the calf (gastrocnemius) muscles. Because tight calf muscles place increased stress on the plantar fascia, this procedure is useful for patients who still have difficulty flexing their feet, despite a year of calf stretches. In gastrocnemius recession, one of the two muscles that make up the calf is lengthened to increase the motion of the ankle. The procedure can be performed with a traditional, open incision or with a smaller incision and an endoscope, an instrument that contains a small camera. Your doctor will discuss the procedure that best meets your needs. Complication rates for gastrocnemius recession are low, but can include nerve damage. Plantar fascia release. If you have a normal range of ankle motion and continued heel pain, your doctor may recommend a partial release procedure. During surgery, the plantar fascia ligament is partially cut to relieve tension in the tissue. If you have a large bone spur, it will be removed, as well. Although the surgery can be performed endoscopically, it is more difficult than with an open incision. In addition, endoscopy has a higher risk of nerve damage. The most common complications of release surgery include incomplete relief of pain and nerve damage. Most patients have good results from surgery. However, because surgery can result in chronic pain and dissatisfaction, it is recommended only after all nonsurgical measures have been exhausted.
Stretching Exercises
Point your toes. To ease foot pain and aching in your feet, lift one foot and roll it downward until the toes are pointed toward the ground. Then flex your foot. Repeat using the other foot. This exercise will help stretch out all the small muscles that are on the bottom of your feet, which can help relieve aching and improve blood circulation. Raise your heels. This exercise is good for relieving toe cramps caused by standing for hours in constricting shoes, says Kurtz. Bonus: It can also strengthen calf muscles and make them look more defined. Stand up and lift your heels so that you are standing on the balls of your feet. Hold for 10 seconds. Repeat 10 times. Squeeze your toes. To strengthen the toes and help alleviate foot pain from hammertoes (when a toe resembles a claw), separate your toes using corks or foam toe separators and then squeeze your toes together for five seconds. Repeat 10 times. Roll a ball. Want to create an instant massage for the bottom of your feet? Roll a golf ball or tennis ball under the ball of your foot. Apply light pressure for about two minutes. This exercise can be helpful for arch pain, cramps, and heel pain from plantar fasciitis. Stretch standing up. A weight-bearing, runners-type stretch can be helpful for foot pain in the arch. Stand up and place your toes against a wall; lean forward a little until you feel your arch stretch. Repeat using the other foot. Stretch sitting down. Sit barefoot and cross your left leg so that your ankle rests on your right thigh. Then hold your toes and bend them back toward your shin, stretching the band of tissue connecting the bottom of the heel to the ball. A University of Rochester study found that people living with plantar fasciitis had a 75 percent chance of having no pain within three to six months of performing this stretch three times daily. Give yourself a foot massage. Nothing spells pain relief like a good foot rub. Use the following technique recommended by Rhonda Crockett, a licensed massage therapist at Ohio State University?s Center for Integrative Medicine in Columbus. Start with your toes, using your thumb to massage them in circular motions. Then move to the arch under your foot and gradually work your way down to the heel, applying pressure with your fingers and palm of your hand. Use lotion to allow your hand to move smoothly over your foot. Relax in a warm bath with Epsom salts. The combination of warm water and Epsom salts will give you a double dose of pain relief and relaxation. Magnesium sulfate, the key compound in Epsom salts, has been found to relax muscles, reduce pain, and sedate the nervous system. Plus, warm water helps improve circulation in the feet and relieve muscle pain. Crockett recommends adding two cups of Epsom salts to a warm bath and soaking for 20 minutes.

What Is Posterior Tibial Tendon Dysfunction ?
Overview
Collapsed arches occur in five percent of adults 40 years and older, especially those who are overweight or maintain sedentary lifestyles. At the onset of the condition, adult acquired flatfoot can be controlled with anti-inflammatory medications, physical therapy, taping, bracing, and orthotics. While most cases of adult-onset flatfoot require surgery, congenital flatfoot is an entirely different condition that is best treated with orthotics in children. Ninety percent of children born with flat feet will be fine with conservative treatment. 
Causes
As the name suggests, adult-acquired flatfoot occurs once musculoskeletal maturity is reached, and it can present for a number of reasons, though one stands out among the others. While fractures, dislocations, tendon lacerations, and other such traumatic events do contribute to adult-acquired flatfoot as a significant lower extremity disorder, as mentioned above, damage to the posterior tibial tendon is most often at the heart of adult-acquired flatfoot. One study further elaborates on the matter by concluding that ?60% of patients [presenting with posterior tibial tendon damage and adult-acquired flatfoot] were obese or had diabetes mellitus, hypertension, previous surgery or trauma to the medial foot, or treatment with steroids?.
Symptoms
Initially, flatfoot deformity may not present with any symptoms. However, overtime as the tendon continues to function in an abnormal position, people with fallen arches will begin to have throbbing or sharp pain along the inside of the arch. Once the tendon and soft tissue around it elongates, there is no strengthening exercises or mechanism to shorten the tendon back to a normal position. Flatfoot can also occur in one or both feet. If the arch starts to slowly collapse in one foot and not the other, posterior tibial dysfunction (PTTD) is the most likely cause. People with flatfoot may only have pain with certain activities such as running or exercise in the early phase of PTTD. Pain may start from the arch and continue towards the inside part of the foot and ankle where the tendon courses from the leg. Redness, swelling and increased warmth may also occur. Later signs of PTTD include pain on the outside of the foot from the arch collapsing and impinging other joints. Arthritic symptoms such as painful, swollen joints in the foot and ankle may occur later as well due to the increased stress on the joints from working in an abnormal position for a long period of time.
Diagnosis
In the early stages of dysfunction of the posterior tibial tendon, most of the discomfort is located medially along the course of the tendon and the patient reports fatigue and aching on the plantar-medial aspect of the foot and ankle. Swelling is common if the dysfunction is associated with tenosynovitis. As dysfunction of the tendon progresses, maximum pain occurs laterally in the sinus tarsi because of impingement of the fibula against the calcaneus. With increasing deformity, patients report that the shape of the foot changes and that it becomes increasingly difficult to wear shoes. Many patients no longer report pain in the medial part of the foot and ankle after a complete rupture of the posterior tibial tendon has occurred; instead, the pain is located laterally. If a fixed deformity has not occurred, the patient may report that standing or walking with the hindfoot slightly inverted alleviates the lateral impingement and relieves the pain in the lateral part of the foot.
Non surgical Treatment
Conservative treatment is indicated for nearly all patients initially before surgical management is considered. The key factors in determining appropriate treatment are whether acute inflammation and whether the foot deformity is flexible or fixed. However, the ultimate treatment is often determined by the patients, most of whom are women aged 40 or older. Compliance can be a problem, especially in stages I and II. It helps to emphasise to the patients that tibialis posterior dysfunction is a progressive and chronic condition and that several fittings and a trial of several different orthoses or treatments are often needed before a tolerable treatment is found. 
Surgical Treatment
In cases of PTTD that have progressed substantially or have failed to improve with non-surgical treatment, surgery may be required. For some advanced cases, surgery may be the only option. Your foot and ankle surgeon will determine the best approach for you.
The Causes And Treatment
Overview
Posterior tibial tendon insufficiency (also called posterior tibial tendon dysfunction or adult acquired flatfoot) has been named literally after failure of the posterior tibial tendon. However, the condition is caused not only by the progressive failure of the posterior tibial tendon; it is also failure of associated ligaments and joints on the inner side of the ankle and foot. This results in collapse of the arch of the foot, along with the deformity which most often becomes the debilitating problem in its later stages. While at the beginning the common symptom is pain over the tendon in the inner part of the hindfoot and midfoot, later on it is the deformity that can threaten a person?s ability to walk. Just as the tendon degenerates and loses its function, other soft tissue on the same inner side of the foot - namely the ligaments - degenerate and fail. Ligaments are responsible for holding bones in place, and when they fail, bones shift to places where they shouldn?t; deformity is the result. The deformity causes malalignment, leading to more stress and failure of the ligaments. 
Causes
Flat feet causes greater pressure on the posterior tibial tendon than normal. As the person with flat feet ages, the muscles, tendons and ligaments weaken. Blood supplies diminish as arteries narrow. These conditions are magnified for obese patients because of their increased weight and atherosclerosis. Finally, the tendon gives out or tears. Most of the time, this is a slow process. Once the posterior tibial tendon and ligaments stretch, body weight causes the bones of the arch to move out of position. The foot rotates inward (pronation), the heel bone is tilted to the inside, and the arch appears collapsed. In some cases, the deformity progresses until the foot dislocates outward from the ankle joint.
Symptoms
Symptoms of pain may have developed gradually as result of overuse or they may be traced to one minor injury. Typically, the pain localizes to the inside (medial) aspect of the ankle, under the medial malleolus. However, some patients will also experience pain over the outside (lateral) aspect of the hindfoot because of the displacement of the calcaneus impinging with the lateral malleolus. This usually occurs later in the course of the condition. Patients may walk with a limp or in advanced cases be disabled due to pain. They may also have noticed worsening of their flatfoot deformity.
Diagnosis
In the early stages of dysfunction of the posterior tibial tendon, most of the discomfort is located medially along the course of the tendon and the patient reports fatigue and aching on the plantar-medial aspect of the foot and ankle. Swelling is common if the dysfunction is associated with tenosynovitis. As dysfunction of the tendon progresses, maximum pain occurs laterally in the sinus tarsi because of impingement of the fibula against the calcaneus. With increasing deformity, patients report that the shape of the foot changes and that it becomes increasingly difficult to wear shoes. Many patients no longer report pain in the medial part of the foot and ankle after a complete rupture of the posterior tibial tendon has occurred; instead, the pain is located laterally. If a fixed deformity has not occurred, the patient may report that standing or walking with the hindfoot slightly inverted alleviates the lateral impingement and relieves the pain in the lateral part of the foot.
Non surgical Treatment
Non-surgical treatment includes rest and reducing your activity until the pain improves. Orthotics or bracing help support the tendon to reduce its pull along the arch, thus reducing pain. In moderate to severe cases, a below knee cast or walking boot may be needed to allow the tendon to rest completely and heal. Physical therapy is an integral part of the non-surgical treatment regimen to reduce inflammation and pain. Anti-inflammatory medication is often used as well. Many times evaluation of your current shoes is necessary to ensure you are wearing appropriate shoe gear to prevent re-injury. 
Surgical Treatment
For those patients with PTTD that have severe deformity or have not improved with conservative treatments, surgery may be necessary to return them to daily activity. Surgery for PTTD may include repair of the diseased tendon and possible tendon transfer to a nearby healthy tendon, surgery on the surrounding bones or joints to prevent biomechanical abnormalities that may be a contributing factor or both.
