In case of impaired functional movement of the operated joint, inability to bend, painful symptoms after forcible movement of the joint, accompanied by local soft tissue swelling of the joint, ligament adhesions after ligament reconstruction should be considered. If there is intra-articular ringing with reduced pain symptoms after passive movement of the joint, due to the separation of the adherent ligaments, it means that the degree of adhesion is relatively mild. In severe ligament adhesions, the main manifestation is stiffness and numbness of the joint, or even deformation of the joint form. For ligament adhesions, treatment can be carried out by soaking the tendons and activating the ligaments with Chinese herbal medicine, massage, passive joint rehabilitation training, and small needle knife ligament release surgery. For severe adhesions, in addition to the above treatment methods, arthroscopic ligament release surgery is required at a hospital joint surgery department.
