Patients who have talus cartilage injuries due to a broken foot often have the cartilage on the surface of the talus broken due to violent impact as well as grinding between the talus and the surrounding bone. Patients are not advised to treat this injury on their own. Patients should go to the orthopedic department and cooperate with the doctor to take the treatment of braking rest, conservative treatment, surgical treatment, functional exercise and so on. The specific treatment measures are as follows: 1. Braking and resting: for this kind of patients, the first thing to do is to keep them strictly braked. At this time, it is necessary to use a plaster or brace to fix the ankle joint in a neutral position, and make the patient stop using the affected side of the foot to bear weight on the ground. 2. Conservative treatment: for patients with small cartilage damage and shallow depth of damage, conservative treatment can be adopted. At this time, we need to apply some anti-inflammatory and nutritive drugs to the patients on the basis of braking and resting. For example, the commonly used ones are celecoxib, glucosamine sulfate and so on. 3. Surgery: For some patients with more serious lesions, such as large area of damage or deeper damage, surgery can be adopted. In this case, arthroscopic surgery is needed to polish the lesion area or fix the peeled bone block. 4. Functional exercise: After the above treatment, patients should be instructed to gradually carry out functional exercises for the ankle joint, such as lying on the bed and practicing ankle flexion and extension activities. In conclusion, it is not recommended to treat the broken ankle by oneself. Patients should go to the orthopedic department.
