Ligament laxity is caused by trauma in most cases and can usually be cured through conservative treatment or ligament repair surgery. Ligaments are fibrous connective tissues with a certain degree of elasticity and toughness and are found in many parts of the body. Commonly, ligament laxity is found in the joints of the limbs, which is mainly caused by trauma, long-term high load on the joints and other factors that cause different degrees of laxity. For ligament laxity of degree I and II, conservative treatment is usually adopted, such as local braking and resting with a brace or plaster, local physical therapy such as low and medium frequency electrotherapy and magnetic therapy, and pain medication when accompanied by pain. The ligament laxity can be restored after standardized treatment. For severe ligament laxity, ligament repair, such as ligament tightening, ligament suturing, or ligament reconstruction may be needed for ligament rupture laxity. Ligament laxity symptoms should be timely to the hospital, improve the relevant examination, clear ligament laxity degree, follow the doctor’s instructions for standardized treatment, so as not to delay the condition.
