When the tendon is broken and attached, generally speaking, there may be sequelae such as localized pain, joint stiffness, and impaired functional activities.
1. Localized pain: after the tendon is broken, it will cause local chronic exudation and recurrent pain, which will affect the flexion and extension of the joints, and if there is little movement, it may lead to swelling that can not be relieved, and there will be a vicious circle.
2. Joint stiffness: some patients lack of rehabilitation exercise, resulting in tendon adhesion, and even cause joint stiffness.
3. Functional activity disorder: after the tendon is broken, because of the tendon adhesion or adhesion with the surrounding soft tissue. If there is no timely rehabilitation and functional training, it will cause the tendon to move limited. Tendon injury may cause impaired functional activities such as flexion and extension.
