The ligaments of the knee are the structures that maintain the stability of the knee joint, mainly including: the medial collateral ligament, the lateral collateral ligament, the anterior cruciate ligament, the posterior cruciate ligament and the joint capsule. After a ligament injury, the stability of the knee joint is damaged and the knee joint becomes unstable. Presentation:History of knee trauma, swelling, pressure pain, joint effusion and limitation of flexion and extension activities in the knee joint. Examination: X-rays, MRI and arthroscopy, including arthroscopy to visualize cruciate ligament, meniscus injury, collateral ligament, joint capsule and cartilage injury. Treatment: The aim is to restore the normal mechanical function of the ligaments and maintain the stability of the knee joint.
1.Conservative treatment:Only a few ligaments are not completely ruptured and there is no acute instability.
2. Surgical treatment: Except for the above cases, all of them need surgical treatment. In recent years, with the continuous improvement of arthroscopic technology, most ligament reconstruction procedures can be treated minimally invasively through arthroscopy.
