Whether or not you can move your knee after a sprain is related to a variety of factors, such as whether or not it is fractured, whether or not it is dislocated, whether or not it is treated in a timely manner, and whether or not you pay attention to rest during the recovery period. If the knee sprain is a ligament injury or inflammation of the ligament, the knee may still be able to move, but the pain will be obvious and more intense when the movement changes. If the knee sprain involves a bone injury, dislocation, or other disease, then swelling, pain, and impaired mobility in the affected area may result in impaired knee mobility. If the knee is sprained, you should go to the hospital in time for a hospital-related examination to clarify the specific damage to the knee and actively cooperate with the doctor’s treatment, and it is recommended that the patient reduces the activities before seeking medical treatment to avoid aggravating the condition.
