What is the Posterior Tibial Tendon? How Does it Affect My Arch?
The posterior tibial tendon is located on the inside of your ankle and plays a major role in supporting and maintaining the arch on the bottom of the foot. Due to the high demands of the tendon with every day life, it can result in overuse of the tendon. This overuse is referred to as posterior tibial tendon dysfunction. When this occurs, patients will eventually develop a flat foot deformity and loss of arch height due to the weakened tendon no longer being able to support the arch. This condition is commonly seen in middle-aged women. Those with diabetes also have an increased risk.
The major problem with posterior tibial dysfunction is that it is a progressive disorder. This means that it will get worse overtime. The initial symptoms of the condition are pain and tendonitis; however there is normally no decrease in strength of the tendon or loss of arch at this stage. As it worsens, the tendon will develop tears and the patient will eventually end up with a decrease in the arch height and a flat foot. With early diagnosis, the progression can normally be slowed, or halted, through the use of orthotics, bracing, immobilization and physical therapy. If the dysfunction is left untreated, or progresses, then it may eventually have to be treated with surgical intervention.
