Posterior tibial tendonitis is an inflammation of the tendon. The tendon represents an extension from the muscle to the bone, through which it exerts mechanical action inserting and mobilizing the joints. The tendon has elastic properties that allow it to modulate the action of muscle and reduce fracture risk in case of rapid violent muscle contractions.
The posterior tendonitis involves the rotulian tendon and the cvadricipital tendon (cvadricipital tendonitis). In rare cases the ischio-Gambier muscles are affected. Finally, the wide fascia syndrome issue is a part of the posterial tibial tendonitis.
