In short, I hope you take away that there's a whole spectrum of both findings and treatments but none of them can start until an accurate diagnosis is made. Being an orthopedic surgeon, my obvious bias would be toward the orthopedic community, especially a Foot & Ankle Fellowship Trained Doc. In my way of thinking, they see these types of problems on a daily basis and are well equipped to handle your problems.
On Sunday I'll get back to single blog topics and, with Kona 4 weeks away, I'll present The World Championship.
Symptoms will be relieved in most patients with appropriate nonsurgical treatment. Pain may last longer than 3 months even with early treatment. For patients who have had pain for many months, it is not uncommon for the pain to last another 6 months after treatment starts.
Decreasing or even stopping activities that worsen the pain is the first step. Switching to low-impact exercise is helpful. Biking, elliptical machines, or swimming do not put a large impact load on the foot, and are generally tolerated by most patients.
Apply cold packs on the most painful area of the posterior tibial tendon for 20 minutes at a time, 3 or 4 times a day to keep down swelling. Do not apply ice directly to the skin. Placing ice over the tendon immediately after completing an exercise helps to decrease the inflammation around the tendon.
Nonsteroidal Anti-inflammatory Medication
Drugs, such as ibuprofen or naproxen, reduce pain and inflammation. Taking such medications about a half of an hour before an exercise activity helps to limit inflammation around the tendon. The thickening of the tendon that is present is degenerated tendon. It will not go away with medication. Talk with your primary care doctor if the medication is used for more than 1 month.
A short leg cast or walking boot may be used for 6 to 8 weeks. This allows the tendon to rest and the swelling to go down. However, a cast causes the other muscles of the leg to atrophy (decrease in strength) and thus is only used if no other conservative treatment works.
Most people can be helped with orthotics and braces. An orthotic is a shoe insert. It is the most common nonsurgical treatment for a flatfoot. An over-the-counter orthotic may be enough for patients with a mild change in the shape of the foot. A custom orthotic is required in patients who have moderate to severe changes in the shape of the foot. The custom orthotic is more costly, but it allows the doctor to better control the position the foot.
A lace-up ankle brace may help mild to moderate flatfoot. The brace would support the joints of the back of the foot and take tension off of the tendon. A custom-molded leather brace is needed in severe flatfoot that is stiff or arthritic. The brace can help some patients avoid surgery.
Physical therapy that strengthens the tendon can help patients with mild to moderate disease of the posterior tibial tendon.
Cortisone is a very powerful anti-inflammatory medicine that your doctor may consider injecting around the tendon. A cortisone injection into the posterior tibial tendon is not normally done. It carries a risk of tendon rupture. Discuss this risk with your doctor before getting an injection.
Surgery should only be done if the pain does not get better after 6 months of appropriate treatment. The type of surgery depends on where tendonitis is located and how much the tendon is damaged. Surgical reconstruction can be extremely complex. The following is a list of the more commonly used operations. Additional procedures may also be required.
Gastrocnemius Recession or Lengthening of the Achilles Tendon
This is a surgical lengthening of the calf muscles. It is useful in patients who have limited ability to move the ankle up. This surgery can help prevent flatfoot from returning, but does create some weakness with pushing off and climbing stairs. Complication rates are low but can include nerve damage and weakness. This surgery is typically performed together with other techniques for treating flatfoot.
Tenosynovectomy (Cleaning the Tendon)
This surgery is used when there is very mild disease, the shape of the foot has not changed, and there is pain and swelling over the tendon. The surgeon will clean away and remove the inflamed tissue (synovium) surrounding the tendon. This can be performed alone or in addition to other procedures. The main risk of this surgery is that the tendon may continue to degenerate and the pain may return.
Tendon transfer can be done in flexible flatfoot to recreate the function of the damaged posterior tibial tendon. In this procedure, the diseased posterior tibial tendon is removed and replaced with another tendon from the foot, or, if the disease is not too significant in the posterior tibial tendon, the transferred tendon is attached to the preserved (not removed) posterior tibial tendon.One of two possible tendons are commonly used to replace the posterior tibial tendon. One tendon helps the big toe point down and the other one helps the little toes move down. After the transfer, the toes will still be able to move and most patients will not notice a change in how they walk.
Although the transferred tendon can substitute for the posterior tibial tendon, the foot still is not normal. Some people may not be able to run or return to competitive sports after surgery. Patients who need tendon transfer surgery are typically not able to participate in many sports activities before surgery because of pain and tendon disease.
Osteotomy (Cutting and Shifting Bones)
An osteotomy can change the shape of a flexible flatfoot to recreate a more "normal" arch shape. One or two bone cuts may be required, typically of the heel bone (calcaneus).If flatfoot is severe, a bone graft may be needed. The bone graft will lengthen the outside of the foot. Other bones in the middle of the foot also may be involved. They may be cut or fused to help support the arch and prevent the flatfoot from returning. Screws or plates hold the bones in places while they heal.
Sometimes flatfoot is stiff or there is also arthritis in the back of the foot. In these cases, the foot will not be flexible enough to be treated successfully with bone cuts and tendon transfers. Fusion (arthrodesis) of a joint or joints in the back of the foot is used to realign the foot and make it more "normal" shaped and remove any arthritis. Fusion involves removing any remaining cartilage in the joint. Over time, this lets the body "glue" the joints together so that they become one large bone without a joint, which eliminates joint pain. Screws or plates hold the bones in places while they heal.Side-to-side motion is lost after this operation. Patients who typically need this surgery do not have a lot of motion and will see an improvement in the way they walk. The pain they may experience on the outside of the ankle joint will be gone due to permanent realignment of the foot. The up and down motion of the ankle is not greatly affected. With any fusion, the body may fail to "glue" the bones together. This may require another operation.
The most common complication is that pain is not completely relieved. Nonunion (failure of the body to "glue" the bones together) can be a complication with both osteotomies and fusions. Wound infection is a possible complication, as well.
Most patients have good results from surgery. The main factors that determine surgical outcome are the amount of motion possible before surgery and the severity of the flatfoot. The more severe the problem, the longer the recovery time and the less likely a patient will be able to return to sports. In many patients, it may be 12 months before there is any
