Generally, the conservative treatment effect of habitual dislocation is average, and the surgical treatment effect is relatively positive. Beijing Sports Hospital, Third Hospital of Beijing Medical University and Jishuitan Hospital can all do this kind of operation. Arthroscopic surgery has the advantages of less trauma and quick recovery. Generally, the lateral patellar retinaculum is relaxed and the medial patellar retinaculum is tightened, so it is not necessary to stick plaster for a long time after operation. We usually use kneepads to practice knee flexion 2-3 weeks after operation, which can be serious half a year after operation if it is conservative. If we strictly follow our requirements and carry out functional training under the guidance of our rehabilitation therapist, it is possible to resume exercise.
