Usually, the cyst will disappear after treatment of posterior horn meniscus tear. If the patient has a torn posterior horn of meniscus with a cyst, conservative treatment or surgery can be chosen under the guidance of the doctor. Under conservative treatment, the patient can wear a brace to stabilize the joint, take medication to improve blood circulation, such as blood circulation and pain relief capsules, and take care of the patient’s health by maintaining a balanced diet to provide sufficient nutrition for the wound to heal. After conservative treatment, the meniscus tear may be repaired and the cyst may disappear. If surgical treatment is chosen, the patient should ask the doctor’s opinion and choose the appropriate surgery under the doctor’s guidance, such as meniscus suture repair. After asking the doctor’s opinion, patients with posterior meniscus horn tear can carry out appropriate rehabilitation training under the doctor’s guidance, so as to avoid muscle atrophy and promote the maintenance of joint function. If you are suffering from posterior horn meniscus tear, you should go to the hospital and ask your doctor for advice and treatment under the doctor’s guidance.
