Joint instability can be treated conservatively or surgically. 1. Conservative treatment: If the joint instability is caused by laxity of the muscles around the joints, functional exercises can be performed to increase the strength of the muscles around the joints, so that the stability of the joints can be increased, avoiding strenuous exercise, and wearing protective gears for protection. 2. Surgery: If the joint instability is caused by trauma, usually there will be ligament damage, through the MRI examination can clarify the degree of damage, and take ligament repair surgery to increase the stability of the joint. Joint instability needs to go to the hospital for further examination, and the specialist will evaluate the degree of instability before judging whether to adopt conservative treatment or surgery.
