Objective To review the research progress of Schöttle’s method in medial patellofemoral ligament reconstruction (MPFLR), and provide the latest knowledge and suggestions for surgical treatment. Methods The studies on Schöttle’s method at home and abroad in recent years were extensively collected, then summarized the problems affecting the accuracy of Schöttle’s method and the new ideas to improve the accuracy of localization. Results It’s vital to accurately locate the femoral tunnel during MPFLR. Malposition of the femoral tunnel is the main cause of postoperative complications and surgical failure. Schöttle’s method is the most well studied and most reproducible method for femoral tunnel localization, which is widely used as the “gold standard”. However, there are still problems that affect the accuracy of Schöttle’s method, including the impact of the internal/external rotation and varus/valgus of the knee on localization accuracy, unclear requirements for X-ray imaging and anatomical landmark reference line drawing standards, no suitable for patients with anatomical variations, and lack of further research on pediatric patients. In recent years, some new ideas are proposed to improve the Schöttle’s method to improve the localization accuracy. Conclusion Future research should combine new technologies such as three-dimensional (3D) printing and intraoperative navigation to develop personalized and intelligent Schöttle’s method, further improving their localization accuracy.
