It is possible to develop a Peroneal Tendon subluxation after an ankle sprain. This often occurs with a high-grade lateral ankle sprain as the Peroneal tendon, and superior retinaculum can become overstretched or tear. If this occurs, it can allow the Peroneal Tendons to subluxate and be misdiagnosed as an irritable chronic ankle sprain or Peroneal Tendonitis.
