Re: Tibialis Posterior Dysfunction
I don't think PTTD ever goes away on its own. It can be managed and lived with, and things can be done to alleviate the symptoms, but I dont think its something you are ever free from. You'll likely get some custom made orthotics, possibly a foot brace, sometimes doctors will cast it to immobilize it, sometimes physical therapy is ordered, anti-inflammatory medicine, night braces, etc. Its not something where you can just wear a shoe insert for a month, and then be healed. Typically its an ongoing and progressive problem. As your foot has already begun to collapse, I wouldn't count on regaining that arch. I have grade 2 pttd (partially torn pttd and torn plantar fascia) and the surgeon said he wouldn't even think about touching the pttd yet. Surgery for this is very invasive and not a procedure to go into lightly.
Theres a lot of information on this site as it is one of the most common foot disorders. If you want more results I would do a search for PTTD on this website as you'll get more answers that way.
