REVISION MEDIAL PATELLOFEMORAL LIGAMENT RECONSTRUCTION USING A QUADRICEPS TENDON GRAFT: A CASE REPORT

Abstract

Introduction

The medial patellofemoral ligament (MPFL) is the main soft tissue that prevents lateral patellar dislocation when the knee is almost fully extended. As these structures lose their ability to function properly, it can lead to more movement and finally displacement of the patella. The semitendinosus or gracillis graft remains the first-line choice in the MPFL reconstruction. However, the quadriceps tendon graft may also be a choice in MPFL reconstruction. However, there are few studies on MPFL reconstruction with a strip of the quadriceps tendon. This case presents the role of the quadriceps tendon graft in MPFL reconstruction.

Case Report

An 18-years-old male came to orthopaedic clinic with complaints of pain in his right knee and accompanied right patellar displacement, which has been suffered since one days ago. History trauma was found. The patient had a history of MPFL reconstruction using hamstring graft. Failure of MPFL reconstruction was occurred, hence the MPFL revision was performed using quadriceps graft. The Kujala score, range of motion, and recurrence were noted as the outcome. At 6 months follow up the patient showed a satisfactory outcome in terms of Kujala score and range of motion. There was no recurrence after the revision of MPFL surgery.

Conclusions

A revision of the MPFL reconstruction using quadriceps tendon provides an favorable outcome in terms of the Kujala score, range of motion, and recurrence.
