Clinically, a rupture of ligaments is characterized by the appearance of severe pain, impaired movement, hemorrhage in the soft tissues, and sometimes into the joint cavity (hemarthrosis), its edema, swelling, for example, filling the knee joint with blood raises the patella over the articular surfaces of the bones. On palpation, fluctuation is noted, and with pressure on the patella and releasing it, you can feel how it strikes the bone, then rises again (symptom of balloting of the patella). The main concern in these cases is to provide peace, apply a pressure bandage to fix the joint. After the resorption of the hemorrhage from the end of 2 weeks after the injury, they proceed to cautious active movements, physiotherapy exercises, physiotherapeutic procedures. With delayed resorption of hemarthrosis, repeated punctures are indicated for suctioning blood and administering antibiotics. With extensive hemorrhages in the joint, scars and cords form on the synovial membrane, which sometimes lead to a significant limitation of joint mobility.
