ligament는 무릎 관절의 중요한 정력성 안정 요소로, 주요 기능은 영향을 제한하는 지도 기능입니다. when the stress that the ligament bears exceeds its yield point, which is the sign of complete rupture, it is often a tear injury, and it may still maintain the general continuity of shape, but the tension that maintains joint stability is lost, and it appears unstable in the straight direction. If the violence is severe and there is a significant displacement of the knee joint, the continuity of the ligament shape may be lost, resulting in a complete rupture, usually manifested as complex instability. During the acute phase, the patient's knee joint swells, hurts, and protective muscle tension occurs, making it difficult to detect positive signs, and early diagnosis is difficult. In the late stage, patients often show varying degrees of knee instability, and unstable knees are prone to repeated injuries, increasing the shear stress on the meniscus and articular cartilage, causing meniscus injury and exacerbating the degeneration of articular cartilage, secondary to traumatic arthritis. Although there are many late-stage ligament reconstruction methods, the long-term efficacy varies, and none can completely restore the original anatomical and physiological function of the ligament. Therefore, early correct diagnosis and treatment are very important for knee ligament injuries.
