Patients not complying with the diagnosis criteria for cruciate ligaments rupture or tear; 2. Patients with an unclosed epiphyseal plate shown on the X-ray film; 3. Patients having underwent internal fixation or reconstruction due to a knee joint fracture; 4. Patients with obvious knee joint degeneration shown on the X-ray film; 5. Patients who cannot make a knee flexion of not less than 90° during operation; 6. Patients undergoing autologous chondrocyte implantation; 7. Patients with medial meniscus or lateral meniscus completely resected; 8. Patients with significant anatomical abnormalities; 9. Pregnant or breast-feeding females or those at a child-bearing age planning to become pregnant; 10. Patients with serious osteoporosis that affects screw implantation; 11. Patients with a malignant tumor that causes failure to effectively fix the implant; 12. Known hypersensitivity to the implant materials; 13.
