Posterior Tibial Tendon Dysfunction - Acquired Flatfoot
Posterior tibial tendon dysfunction most frequently develops in one foot, but it can affect both feet. Symptoms are usually progressive, meaning they get worse over time. You may first notice pain, redness, and swelling along the inside of your ankle and foot. As the arch in your foot flattens, you may experience pain in your outer and midfoot, weakness, and the inability to stand on your toes.
Your doctor will ask you to stand or move your foot in certain ways so that it can determined how your tendon is functioning. X-rays, ultrasound, or magnetic imaging resonance (MRI) imaging may be used to provide pictures of your ankle and leg structures.
Recovery is individualized. The amount of time you need to heal depends on the extent of your condition and the procedures that you received. Your doctor will let you know what to expect.
