A meniscus ligament injury that hasn’t healed in 5 months may be in the normal recovery period after surgery, or it may be related to severe ligament damage and incorrect exercise style and timing. It can be treated with a change in exercise program or with surgery. Meniscus ligament injuries usually cause pain and swelling in the knee, and may even affect the ability to exercise. If the injury is only minor and does not produce significant structural changes, it can be treated conservatively and recovery usually takes 1 to 2 months. If the meniscus injury is more serious and produces obvious structural changes, surgical repair is usually required, and the recovery time usually takes 3~6 months or even longer. After the acute postoperative period, functional exercise is required. If the patient’s meniscus ligament injury is severe and not treated with surgery in time, or the exercise mode is not appropriate after surgical treatment, or if the patient fails to exercise in time, it is possible that the meniscus injury is still not healed after 5 months. However, it is also possible that it is still in the postoperative recovery period, and it is recommended to continue the treatment and rehabilitation training. It is recommended that patients consult their doctors in time to clarify the reasons for failure to recover in time, and carry out reasonable treatment and rehabilitation exercises under the doctor’s guidance.
