Soft Tissue Impingement

Anterior.  

• Chronic ankle pain after an ankle ''sprain'' is a well-documented problem and is seen in 20% to 40% of these patients.
• Pain is usually located anterolaterally, rarely anteromedially.
• Wolin described a ''meniscoid'' band between the fibula and the talus in 1950. This mass was thought to be hyalinized connective tissue
   from the talofibular joint capsule.  
• impingement of this meniscoid tissue led to pain and swelling in the
   ankle.

The differential diagnosis for chronic pain secondary to ankle sprain includes osteochondral lesions of the talus, calcific ossicles, peroneal subluxation or dislocation, tarsal coalition, subtalar joint dysfunction, degenerative joint  disease, and soft tissue impingement.
