Patellar dislocation can be self-healed in some patients, but not all patients can be self-healed. 1. After patella dislocation, some patients can heal themselves through braking, manipulation and external fixation. 2. For patellar dislocation caused by knee ligament injury or rupture, surgical repair and plaster fixation are needed to cure it, which cannot be recovered by itself. 3. The dislocation caused by patella fracture due to trauma also needs surgical treatment and fixation. Therefore, whether patellar dislocation can be cured by itself should be judged according to the cause of the dislocation and the degree of injury. If the above symptoms occur, it is recommended to go to the hospital in time for early and regular treatment.
