The sequelae of a tendon or ligament injury, i.e., a partial injury, may gradually improve with recovery, while some of the sequelae of a complete rupture without proper treatment may be permanent. The sequelae of a tendon or ligament injury are primarily dysfunction or loss of motion. Therefore, whether or not the sequelae of an injury will be permanent depends primarily on the extent of the injury. For partial or mild ligament injuries, there are generally no permanent sequelae, and in most cases the ligament will gradually recover and therefore the remaining dysfunction improves or returns to normal. In the case of complete rupture of tendon or ligament, if the injury is not treated in time or the effect of treatment is unsatisfactory, permanent dysfunction of movement will remain, accompanied by ligament contracture, etc., and the after-effects may be aggravated and permanent. In case of tendon or ligament injury, it is recommended to go to regular hospitals in time, complete the relevant examination, clarify the severity of the injury, and then follow the doctor’s instructions for standardized treatment, so as to avoid delaying the condition and leaving long-term sequelae.
