When conservative, noninvasive treatments prove unsuccessful, podiatrists will often turn to surgery as the last line of treatment for their patients. If patients are suffering from joint pain, issues in mobility, or are seeking to correct a deformity, joint replacement surgery is an effective option. Joint replacement surgery is also successful in treating arthritis, which is the most common cause of improperly working joints.

Patients with symptoms that include joint pain, stiffness, limping, muscle weakness, limited motion, and swelling are typically considered for joint replacement surgery. Range of motion and activity post-surgery will vary between patients and depending on the specific surgery performed, the affected joint, and the damage that will need to be repaired.

Joint replacement surgery replaces the damaged cartilage and bone, the latter if required. The damaged cartilage is typically replaced with a prosthesis that is attached to the bone, allowing the implant to grow into the bone. Following surgery, the patient will typically undergo physical therapy to become familiar with movement using the replaced joint.

Flatfoot is a foot condition in which the arch of the foot has either partially or totally dropped or has never developed. While it is common in babies and small children, it can become a problem for them in adulthood if the arch never forms. For adults, the development of flat feet can be brought upon by injury, as a result of pregnancy due to increased elasticity, or obesity. Those who have health concerns such as rheumatoid arthritis or diabetes may also be at greater risk for developing the condition.

If you suspect that you have flat feet, it is best to consult your podiatrist. Your foot doctor will examine the suspected foot and observe how it looks while you sit and stand. He or she may take an X-ray to determine how serious the condition is. Some common signs of flatfoot include toe drift, in which the toes and front part of the foot point outward, a short Achilles tendon, and a heel that tilts outwardly while the ankle tilts inward.

Once flatfoot has been diagnosed, your podiatrist may suggest one of several treatment options. Flat feet can be rigid, in which the feet appear to have no arch even when the person is not standing; or flexible, in which the person appears to have an arch while not standing, but once standing the arch disappears. Those with flexible flatfoot may be told to reduce any activities that cause pain and to avoid extended periods of walking or standing. Another suggestion may be weight loss, as excessive weight may be placing pressure on the arches

In few cases, if the condition is severe and all other methods have been exhausted surgery may be required. This is normally avoided, however, due to a lengthy recovery time and high cost.

Foot and ankle injuries are common among people who participate in sports. Several factors contribute to this. They include failing to stretch or warm up properly, not wearing the proper type of shoe and not taping or providing other types of support for the ankle or foot. The most common foot and ankle injuries suffered by people involved in sports are plantar fasciitis, ankle sprains and Achilles tendon damage or ruptures. If not treated properly, they can lead to permanent disability.

Treating these injuries is relatively simple if they are identified and addressed early. Many athletes dismiss the initial aches and pains associated with injury as just soreness or tired muscles. Their first response is usually to try to work through it. This can lead to serious problems. Many minor injuries are made far more serious when athletes continue to put strain and pressure on them. That attitude can change a mild strain into a serious strain and a minor tear into a rupture. Athletes should have unusual aches and pains evaluated by a skilled medical professional.

Plantar fasciitis is a painful injury. It is inflammation of the plantar fascia, the thick band of tissue running from the heel to the base of the toes. If left untreated, it can lead to a degenerative disease called plantar fasciosis. There are several effective treatments for this ailment. Doctors often prescribe rest, massages, stretching, night splints, physical therapy, anti-inflammatory medication, corticosteroids or surgery, usually in that order. The most effective treatment for plantar fasciitis is orthotics, which offers foot support. Surgery is occasionally used as a last resort, but it comes with the risk of nerve damage and infection and often does not stop the pain.

The Achilles tendon is the largest tendon in the body. It connects the calf muscles to the heel bone. Running, jumping and walking all impact this tendon. Two common injuries to the Achilles tendon are tendonitis and a rupture of the tendon. Tendonitis is inflammation in the tendon often caused by an increase in the amount of stress placed on it. Non-surgical treatments include rest, ice or anti-inflammatory medication.  A rupture (tear) of the Achilles tendon can be treated by placing the lower leg in a cast for several weeks or with surgery. Many physicians feel surgery is the better option because it lowers the risk of re-ruptures. Both methods require 4 to 6 months of rehabilitation.

Ankle sprains are the most common sports related foot and ankle injury. A sprain occurs when the ligament holding the ankle bones and joint stretches beyond its normal range. It can be treated non-surgically with a combination of rest, ice wrapped around the joint for 30 minutes immediately after injury, compression by a bandage and elevating the ankle above the heart for 48 hours. This combination is referred to as RICE. Severe ankle sprains in which the ligaments are torn may require reconstructive surgery followed by rehabilitation.

Although rheumatoid arthritis attacks multiple bones and joints throughout the entire body, ninety percent of people who actually develop this condition usually do so in the foot or ankle area. Those who develop this kind of arthritis in the feet usually develop symptoms around the toes and forefeet first, before anywhere else. Rheumatoid arthritis appears to have a genetic component. If it runs in the family, then you will be more likely to develop it as well.

Rheumatoid arthritis is an autoimmune disorder in which the body’s own immune system attacks the lining of the membranes surrounding the joints. This causes inflammation of the membrane lining, and the gradual destruction of the joint’s cartilage and even bone.

Some of the most common symptoms that are associated with RA include pain and swelling of the feet. Stiffness in the feet is also another common symptom that people experience. Those who have RA in the feet usually feel the pain in the ball or sole of their feet. This can get to be very painful at times. A person's joints can even shift and become deformed after a period of time.

In order to properly diagnose RA in the feet it is usually necessary for a doctor or podiatrist to evaluate the area. Your doctor will also question you about your medical history, occupation, etc., to determine whether anything in your lifestyle may have triggered the condition. There are a number of tests that may be performed to help diagnose RA, such as a rheumatoid factor test. There is, however, no one single test that will tell you for sure if you have RA. There are different X-rays that can be taken as well to determine if a person has RA in their feet.

There is a range of treatment options for rheumatoid arthritis. Treatment of RA is usually a lifelong process that includes a variety of methods of treatment and therapy. Your doctor can prescribe special shoes that should help with arch support as well as heel support. A physical therapist can help those with this condition learn exercises which will keep their joints flexible. Surgery may be needed to correct some of the issues with the feet, such as bunions, and hammertoes. Fusion is usually the most successful surgical option for rheumatoid arthritis. However, people need to keep in mind that there are some risks associated with these surgeries.

While proper foot care is important for everybody, senior citizens have the tendency to be more susceptible to certain foot conditions. The elderly should therefore be well informed about any problems that may arise and about what they can do to properly avoid or treat them.

Some of the most common foot problems seniors are susceptible to include foot ulcers, ingrown toenails, fallen arches, and fungal nails. A foot ulcer is an open sore on the foot and can be a result of diabetes and decreased sensation in the feet. An ingrown toenail is defined as when the nail grows into the side of the toe. Fallen arches are indicated by the instep of the foot collapsing. A fungal nails is a condition that results in deformed and discolored toenails.

In order to avoid these conditions it is recommended that the feet be inspected by the patient on a regular basis. If these inspections are carried out routinely, there is a good likelihood that problems can be identified before they become severe, or can even be avoided altogether. If any abnormality is discovered, it is important that the individual consult a podiatrist for diagnosis and information on treatment options.

Proper foot hygiene is also important. Making sure that you always have clean, dry socks on can be a major deterrent to many different problems including bacterial infections, foot odor, and certain types of fungus. Wet feet are a major cause of many of these problems.  If your socks get wet, it is important to change them. Walking around in wet socks may not only lead to various infections, but can irritate the skin and result in a number of various complications. Clean, dry feet are less likely to be affected by fungal and other infections.

As people age, the fat present on your feet begins to deteriorate. The protective nature of this fat keeps the feet healthy by providing a barrier between your bones and the ground. This also aids in giving the skin on the feet a certain amount of elasticity. This is one factor that causes elderly people to develop some serious foot issues. Foot moisturizers can be helpful to avoid certain problems associated with this. However, water-based moisturizers do not work as well for elderly people as they do for the young. Instead, it is more effective to use an emollient instead. An emollient is effective because it binds the water in the foot, keeping it from becoming absorbed too readily which will result in dry skin. Emollients also have a special property called occlusion, which provides a layer of oil on the skin. This layer prevents the foot from drying up and can be very effective in treating dry skin disorders.  If you can keep the skin on your feet healthy, this will substantially reduce the number of foot problems you will encounter in old age.

Proper footwear is another way to keep feet healthy. Shoes that fit well and provide proper support help prevent ingrown toenails and fallen arches.

Certain medical conditions such as diabetes or poor blood circulation increase the risk for foot issues. For individuals with any of these conditions it is extremely important to conduct regular foot inspections to make sure that there are no sores or infections present.
