The ligament rupture in the leg should be examined early by MRI and related specialist examination to further confirm the rupture of the ligament and to check the stability of the related joint to consider whether to carry out surgical treatment. Most ligament ruptures require incision surgery, which can be performed in the following three ways: first, direct suturing of the ligament, if there is no defect at the severed end of the ligament and it is relatively intact, the ligament can be directly sutured, and the ligament can continue to grow after suturing, so that the integrity of the ligament can be restored and the function of the joint can be restored to normal. If the ligament rupture is difficult to be sutured directly at the stop point, continuous suturing of the bone anchor nail is needed to restore the rupture of the ligament to normal. Reconstruction of the ligament. If the defect is large after the ligament rupture, direct suturing or bone anchor stapling is not possible, reconstruction of the ligament is needed.
