The Achilles tendon is used in almost every activity that involves moving your foot. If you can walk, run, jump or stand on your tip-toes, make sure to thank your Achilles. It's the largest and strongest tendon in your body, running from the calf down to the foot, and can withstand more than a 1,000 pounds of force.
Unfortunately, when the Achilles tendon is injured, it can not only be very painful, but also put a swift end to mobility, as you once knew it.
Your posterior tibal tendon takes a daily beating. The constant pressure of supporting your foot and arch while walking can sometimes be too much for this tendon, resulting posterior tibal tendon dysfunction. This very common condition causes swelling and pain and if treated early can have success with non-invasive treatments.
The two Peroneal Tendons are located directly behind the outside ankle and function to stabilize and move the joint outward.
These tendons play a critical role in balancing the ankle and back of the foot. They also prevent the foot from turning inward repetitively. The potential problem is that they are slightly weaker than the muscles and tendons on the inside of the ankle. For that reason, they are prone to injury from ankle turns and rolls.
