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

Not Applicable

Recruiting

• Conditions: Recurrent Patellar Dislocation
• Interventions: Other: Patients with patellar dislocation undergo patellar femoral medial reconstruction

• Registration Number: NCT04456881
• Lead Sponsor: Peking University Third Hospital

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.

Primary Outcome Measures

Name	Time	Method
Tegner activity level score	1 year after operation	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.
Lysholm score	1 year after operation	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.
International Knee Documentation Committee (IKDC) 2000	1 year after operation	International Knee Documentation Committee (IKDC) 2000. The higher values represent a better outcome.
