Ankle ArthritisAnkle arthritis, by simple definition, is the inflammation and degeneration of the joint surfaces. These surfaces include the end of the tibia (shin bone) and the “dome” of the talus bone, which lies just underneath the tibial articular surface. This is the main junction between the leg and the foot. The inner portion of the lateral malleolus (end of the fibula bone) is frequently involved as well.
As with other joints, this can occur at various levels of severity, and caused from a variety of factors, such as injury, obesity, genetics and chronic instability.
As you can see in the above x-ray, the spacing between the shin bone (tibia) and the talus bone is gone, worn down. The "tread" has been worn off the proverbial tire. Once the bones begin to rub together like this, pain, swelling and mobility issues increase. Weight bearing can become difficult and uncomfortable. Many people will have a noticeable limp and have trouble wearing shoes due to the level of swelling and deformity that can develop.
