[Research progress of Schöttle's method for femoral tunnel localization in medial patellofemoral ligament reconstruction].

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.

[Research progress on femoral attachment positioning during medial patellofemoral ligament reconstruction].

Objective: To review research progress on femoral attachment positioning during medial patellofemoral ligament (MPFL) reconstruction, so as to provide a reference for accurate positioning in clinic.

Methods: The literature at home and abroad on femoral attachment positioning during MPFL reconstruction was extensively reviewed and summarized.

Results: MPFL is the main ligament that restricts patellar outward migration, so MPFL reconstruction is the main treatment for patellar dislocation, but the accuracy of intraoperative femoral attachment positioning will significantly affect the effectiveness.
