- Brief summaryChronic ankle instability is a common result of an ankle sprain. The patients we see at the orthopaedics department often suffer from complaints for an unnessesarily long period of time. Additionally the longer the period of complaints and recurrent sprains, the lower the chance of surgical succes. We are going to develop a prediction model to assess which factors contribute to chronicity. This way patients with a greater chance on chronic instability can be identified and may become eligible for early surgical stabilization.
