Post-Tibial Tendonitis is a strain placed on the posterior tibial tendon. The posterior tibial tendon runs along the inside of the ankle and the foot. When there is post-tibial tendon dysfunction, the tendon does not function to hold up the arch, resulting in flat feet. This can lead to heel pain, arch pain, plantar fasciitis and/or heel spurs. With post-tibial tendonitis, pain will be more severe upon weight bearing, especially while walking or running.
Post-Tibial Tendonitis occurs when the muscle is overused and the tendon (soft tissue) that connects the muscle to the bone is strained. Years of excessive-pronation (flat feet) can also lead to posterior tibial tendon dysfunction. If you keep overusing the muscle, damage to the tendon builds up and tendonitis develops. At first the pain or swelling may come and go quickly, but eventually the problem may become more permanent (chronic).
To treat post-tibial tendonitis, you can reduce the symptoms by limiting activity to control the pain and swelling. Stay off your feet a few days, and then slowly increase your activity. Rest allows the tissues in your foot to heal.
Conservative treatments (non-surgical treatments) include wearing a foot orthotic with rear foot posting and longitudinal arch support to reduce strain on the post tibial tendon and prevent excessive stretching of the plantar fascia. The orthotic should also be designed with materials to comfort the foot and absorb shock.
Vary exercise routines. The variety will keep one set of muscles from being under continuous stress.
If the problem persists, consult your podiatrist.
