Postoperative evaluations
After the surgery for 12 months, the symptoms, range and stability of joint flexion and extension, Lysholm score, Tegner score, and IKDC score were evaluated. X-ray and MRI were performed to reveal the changes of bone tunnel and ligament healing. Lachman, Drawer, Valgus/Varus stress, and axial displacement tests were performed to evaluate the stability of the knee joint.
