Management of patellar dislocation
A first event may be managed conservatively, with a period of immobilisation, after which sports may be limited for some months. If there is a subsequent event, the patient is usually subjected to a full investigation of any underlying causes and surgery may be planned. This may include a reconstruction of the MPFL. In patients where there is a marked problem with the anatomy, such as trochlear dysplasia, corrective surgery may be undertaken.
