Tibialis Posterior Tendon Dysfunction
Also known as Tibialis posterior dysfunction, posterior tibial tendon dysfunction or adult acquired flatfoot: this condition is associated with a lower arch, pronated foot type and is something which must be managed quickly when it occurs.
Split into multiple stages, this condition, if not managed quickly, is progressive and will cause deformity. It is the only common foot problem in an otherwise healthy population that should be managed quickly and agressively, with strong orthotics, exercises and close monitoring.
The tibialis posterior tendon attaches onto a bone caled the navicular and this bone is responsible for holding the arch up. If you start to feel pain on the inside of the ankle which is either painful when getting up from rest or on increased periods of walking, then you should get some assistance quickly.*
Please note, this is the only condition that I am stressing seeking help from someone specialised. Other conditions can be 'watchfully neglected'!
You will likely need a pair of insoles, to purchase some good quality trainers, potentially to lose weight and also to do exercises. Please do not hold off on booking until you have done these things - the number of people who delay getting assistance until they have tried the above end up requiring more treatment due to greater severity of the condition. It will save you money!
Tibialis posterior tendon dysfunction occurs on the inner edge (big toe side) of the ankle and runs to halfway along your arch. It might also cause your arch to flatten.
