If the knee creaks and hurts, the following treatment measures can be taken: 1. Patients should immediately keep braking and rest, do not continue to use weight-bearing activities of the knee joint at this time, and can use elastic bandages or knee pads to protect the knee joint. Many patients habitually over-activate the knee at this time in the hope that the symptoms will be eliminated through this activity. In fact, such measures are not advisable and may aggravate the damage inside the knee joint.2 Patients should go to an orthopedic or sports medicine department at a level 2 or higher hospital as soon as possible to clarify the cause of the symptoms and then target them for treatment. If, after examination and diagnosis, it is clear that the injury is mild, then conservative treatment is preferred, with strict bed rest, braking and rest, and the use of anti-inflammatory, anti-swelling and pain-relieving drugs, If, after consultation, it is clear that this type of injury is very serious, then surgery may be required. Arthroscopic surgery of the knee is most commonly used for this condition.
