Overview

The adult acquired flatfoot (AAF) is a progressive, symptomatic (painful) deformity resulting from gradual stretch (attenuation) of the tibialis posterior tendon as well as the ligaments that support the arch of the foot. Although the posterior tibialis tendon plays a significant role, this pathology has recently been recognized as involving failure of other interosseous ligaments, such as the spring ligament. Due to the complexity of this pathology, posterior tibial tendon dysfunction (PTTD) is now referred to as adult acquired flatfoot. Severe flatfoot associated with AAF can lead to other problems, such as plantar fascial tension, tendon pain, rearfoot subluxation, and ankle osteoarthritis

Causes

Adult acquired flatfoot is caused by inflammation and progressive weakening of the major tendon that it is responsible for supporting the arch of the foot. This condition will commonly be accompanied by swelling and pain on the inner portion of the foot and ankle. Adult acquired flatfoot is more common in women and overweight individuals. It can also be seen after an injury to the foot and ankle. If left untreated the problem may result in a vicious cycle, as the foot becomes flatter the tendon supporting the arch structure becomes weaker and more and more stretched out. As the tendon becomes weaker, the foot structure becomes progressively flatter. Early detection and treatment is key, as this condition can lead to chronic swelling and pain.

Symptoms

Your feet tire easily or become painful with prolonged standing. It’s difficult to move your heel or midfoot around, or to stand on your toes. Your foot aches, particularly in the heel or arch area, with swelling along the inner side. Pain in your feet reduces your ability to participate in sports. You’ve been diagnosed with rheumatoid arthritis; about half of all people with rheumatoid arthritis will develop a progressive flatfoot deformity.

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

This condition may be treated with conservative methods. These can include orthotic devices, special shoes, and bracing. Physical therapy, rest, ice, and anti-inflammatory medication may be prescribed to help relieve symptoms. If the condition is very severe, surgical treatment may be needed.

Surgical Treatment

A new type of surgery has been developed in which surgeons can re-construct the flat foot deformity and also the deltoid ligament using a tendon called the peroneus longus. A person is able to function fully without use of the peroneus longus but they can also be taken from deceased donors if needed. The new surgery was performed on four men and one woman. An improved alignment of the ankle was still evident nine years later, and all had good mobility 8 to 10 years after the surgery. None had developed arthritis.

Overview

Achilles tendinitis is a common condition that causes pain along the back of the leg near the heel. The Achilles tendon is the largest tendon in the body. It connects your calf muscles to your heel bone and is used when you walk, run, and jump. Although the Achilles tendon can withstand great stresses from running and jumping, it is also prone to tendonitis, a condition associated with overuse and degeneration. Tendons become inflamed for a variety of reasons, and the action of pulling the muscle becomes irritating. If the normal, smooth gliding motion of the tendon is impaired, the tendon will become inflamed and movement will become painful. This is called tendonitis, meaning inflammation of the tendon. Achilles tendonitis is typically not related to a specific injury. The problem results from repetitive stress to the tendon. This often happens when we push our bodies to do too much, too soon, but other factors can make it more likely to develop tendinitis, including: a sudden increase in the amount or intensity of exercise activity, tight calf muscles, or a bone spur that has developed where the tendon attaches to the heel bone.

Causes

The causes of Achilles tendonitis all appear to be related to excessive stress being transmitted through the tendon. Weak calf muscles, poor ankle range of motion, and excessive pronation have all been connected with the development of Achilles problems.The upshot is that all of these factors, plus training volume and so on, result in damage to the tendon. Much like a bungee cord is made up of tiny strands of rubber aligned together, tendons are comprised of small fiber-like proteins called collagen. Pain in the Achilles tendon is a result of damage to the collagen. Because of this, treatment options should start with ways to address this.

Symptoms

The symptoms associated with Achilles tendonitis and tendonosis include, Pain-aching, stiffness, soreness, or tenderness-within the tendon. This may occur anywhere along the tendon?s path, beginning with the tendon?s attachment directly above the heel upward to the region just below the calf muscle. Often pain appears upon arising in the morning or after periods of rest, then improves somewhat with motion but later worsens with increased activity. Tenderness, or sometimes intense pain, when the sides of the tendon are squeezed. There is less tenderness, however, when pressing directly on the back of the tendon. When the disorder progresses to degeneration, the tendon may become enlarged and may develop nodules in the area where the tissue is damaged.

Diagnosis

The diagnosis is made via discussion with your doctor and physical examination. Typically, imaging studies are not needed to make the diagnosis. However, in some cases, an ultrasound is useful in looking for evidence of degenerative changes in the tendon and to rule out tendon rupture. An MRI can be used for similar purposes, as well. Your physician will determine whether or not further studies are necessary.

Nonsurgical Treatment

The initial aim of the treatment in acute cases is to reduce strain on the tendon and reduce inflammation until rehabilitation can begin. This may involve, avoiding or severely limiting activities that may aggravate the condition, such as running or uphill climbs. Using shoe inserts (orthoses) to take pressure off the tendon. Wear supportive shoes. Reducing Inflammation by icing. Taking non-steroidal anti-inflammatory drugs. Heel cups and heel lifts can be used temporarily to take pressure off the tendon, but must not be used long term as it can lead to a shortening of the calf. Calf Compression Sleeves. Placing the foot in a cast or restrictive ankle-boot to minimize movement and give the tendon time to heal. This may be recommended in severe cases and used for about eight weeks.

Surgical Treatment

Surgery for an Achilles tendon rupture can be done with a single large incision, which is called open surgery. Or it can be done with several small incisions. This is called percutaneous surgery. The differences in age and activity levels of people who get surgery can make it hard to know if Achilles tendon surgery is effective. The success of your surgery can depend on, your surgeon’s experience. The type of surgery you have. How damaged the tendon is. How soon after rupture the surgery is done. How soon you start your rehab program after surgery. How well you follow your rehab program. Talk to your surgeon about his or her surgical experience. Ask about his or her success rate with the technique that would best treat your condition.

Prevention

Warm up slowly by running at least one minute per mile slower than your usual pace for the first mile. Running backwards during your first mile is also a very effective way to warm up the Achilles, because doing so produces a gentle eccentric load that acts to strengthen the tendon. Runners should also avoid making sudden changes in mileage, and they should be particularly careful when wearing racing flats, as these shoes produce very rapid rates of pronation that increase the risk of Achilles tendon injury. If you have a tendency to be stiff, spend extra time stretching. If you?re overly flexible, perform eccentric load exercises preventively. Lastly, it is always important to control biomechanical alignment issues, either with proper running shoes and if necessary, stock or custom orthotics.
