Fallen arches, or flatfoot, is a condition in which the arch on the inside of the foot is flat and the entire sole of the foot rests on the ground. It affects about 40 percent of the general population. Although flat feet in and of themselves are not usually problematic, they can create problems in the feet, hips, ankles and knees. Pain may be experienced in the lower legs if there are alignment problems and if the individual is engaged in a lot of heavy, high-impact activities that put stress on the bones and muscles of the lower legs.
Most commonly fallen arches in adulthood can arise due to Posterior Tibial Tendon Dysfunction (PTTD). The posterior tibial tendon plays a pivotal role in holding up the arch of the foot, damage to this tendon results in the arch collapsing. Another cause of acquired flat feet in adulthood may be due to Rheumatoid arthritis as this disease attacks the bone, cartilage and ligaments in the foot causing it to change shape and flatten. Injury to the ligament, fracture and/or dislocation of the bones in the mid foot can all lead to a flat foot deformity. Adult acquired flat fleet can also arise in people who have diabetes or a neurological condition which limits normal feeling in the foot, the muscles in feet switch off, the tendons and ligaments weaken, and the arch eventually collapses.
Knee/Hip/Back Pain - When the arch collapses in the foot, it triggers a series of compensations up the joint chain, leading to increased stress on the knee, pelvis and low back. Plantar fasciitis - This condition is characterized by heel pain, especially with the first few steps you take. The plantar fascia stretches as the arch falls, putting stress on the heel. Bunions - If you see a bony bump developing at the base of your big toe, you are likely developing a bunion. It may be swollen, red or painful when it rubs against your shoe. A flattened arch spreads the forefoot and causes the big toe to deviate toward the second toe. Shin splints - This term generally refers to pain anywhere along the shinbone. It is typically due to overuse and is aggravated after exercise and activity.
Flat feet are easy to identify while standing or walking. When someone with flat feet stands, their inner foot or arch flattens and their foot may roll over to the inner side. This is known as overpronation. To see whether your foot overpronates, stand on tiptoes or push your big toe back as far as possible. If the arch of your foot doesn't appear, your foot is likely to overpronate when you walk or run. It can be difficult to tell whether a child has flat feet because their arches may not fully develop until they're 10 years of age.

Non Surgical Treatment
The type of treatment will depend on the stage of PTTD present. There are four stages of posterior tibial tendon dysfunction. Stage I. The posterior tibial tendon is inflamed but has normal strength. There is little to no change in the arch of the foot. The patient can still perform a single-limb heel rise and has a flexible hindfoot. Orthotic treatment options include modified off the shelf inserts and custom molded orthotics. Stage 2. The tendon is partially torn or shows degenerative changes and as a result loses strength.There is considerable flattening of the arch without arthritic changes in the foot. The patient cannot perform single-limb heel rise. Pain is now present on the lateral aspect of the ankle. Orthotic treatment is similar as that in stage I, with the addition of more rigid arch supports and wedging. Stage 3. Results when the posterior tibial tendon is torn and not functioning. As a result the arch is completely collapsed with arthritic changes in the foot. A solid ankle AFO is suggested in conjunction with a modified orthopedic shoe. Stage 4. Is identical to stage three except that the ankle joint also becomes arthritic. A rigid AFO and modified orthopedic shoe is required.
Surgical procedures for flat feet vary depending on the root cause of the condition. Surgical correction to control pronation may include bone implants or Achilles tendon lengthening. Tendon transfer, which is a procedure to re-attach a tendon to another area of bone, may also be used to reduce pronation and improve foot function.
Going barefoot, particularly over terrain such as a beach where muscles are given a good workout, is good for all but the most extremely flatfooted, or those with certain related conditions such as plantar fasciitis. Ligament laxity is also among the factors known to be associated with flat feet. One medical study in India with a large sample size of children who had grown up wearing shoes and others going barefoot found that the longitudinal arches of the bare footers were generally strongest and highest as a group, and that flat feet were less common in children who had grown up wearing sandals or slippers than among those who had worn closed-toe shoes. Focusing on the influence of footwear on the prevalence of pes planus, the cross-sectional study performed on children noted that wearing shoes throughout early childhood can be detrimental to the development of a normal or a high medial longitudinal arch. The vulnerability for flat foot among shoe-wearing children increases if the child has an associated ligament laxity condition. The results of the study suggest that children be encouraged to play barefooted on various surfaces of terrain and that slippers and sandals are less harmful compared to closed-toe shoes. It appeared that closed-toe shoes greatly inhibited the development of the arch of the foot more so than slippers or sandals. This conclusion may be a result of the notion that intrinsic muscle activity of the arch is required to prevent slippers and sandals from falling off the child?s foot.
Time off work depends on the type of work as well as the surgical procedures performed. . A patient will be required to be non-weight bearing in a cast or splint and use crutches for four to twelve weeks. Usually a patient can return to work in one to two weeks if they are able to work while seated. If a person's job requires standing and walking, return to work may take several weeks. Complete recovery may take six months to a full year. Complications can occur as with all surgeries, but are minimized by strictly following your surgeon's post-operative instructions. The main complications include infection, bone that is slow to heal or does not heal, progression or reoccurrence of deformity, a stiff foot, and the need for further surgery. Many of the above complications can be avoided by only putting weight on the operative foot when allowed by your surgeon.
