Arthroscopic Clinical Study of Double Bundle Anatomical Reconstruction of Medial Patellofemoral Ligament

Study Overview
=================
Brief Summary
-----------------
Objective: To study the clinical effect of double-beam anatomical reconstruction of medial patellofemoral ligament under arthroscopy. Methods: Double-beam anatomical reconstruction of medial patellofemoral ligament was performed under arthroscopy in patients admitted to our hospital for treatment of recurrent patellar dislocation. Carry out preoperative and postoperative evaluations, and conduct preoperative and postoperative comparative studies to clarify the clinical effect of the procedure. Expected results: Arthroscopic double-beam anatomical reconstruction of the medial patellofemoral ligament can effectively restore the stability of the patella and the motor function of the knee joint. Expected conclusion: Arthroscopic double-beam anatomical reconstruction of the medial patellofemoral ligament is an effective minimally invasive technique. Keywords: knee joint; medial patellofemoral ligament; double-beam anatomical reconstruction; arthroscopy

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Lysholm score | The Lysholm score consists of eight items including limping, locking, pain, stair climbing, use of supports, instability, swelling, and squatting. The higher values represent a better outcome. | 1 year after operation | 
| International Knee Documentation Committee (IKDC) 2000 | International Knee Documentation Committee (IKDC) 2000. The higher values represent a better outcome. | 1 year after operation | 
| Tegner activity level score | The highest level of activity that you participated in before your injury and the highest level you are able to participate in currently. The higher values represent a better outcome. | 1 year after operation |
