Introduction:

Alterations of the patellofemoral joint are one of the most common causes of pain and inflammation as well as joint damage and instability of the knee. Patellofemoral instability is a common multifactorial entity, requiring realignment by proximal, distal, or a combination of techniques. Within the proximal procedures in soft tissues, is the medial patellofemoral ligament plasty (MPFL), which aims to realign the patella medially and restore the anatomy between the quadricipital tendon, patella and tubercle of the tibia.

Objective:

To demonstrate that the plasty of the LPFM with quadriceps autograft is an effective technique with a low level of complications.

Material and methods:

Observational, longitudinal, retrospective, descriptive, basic and clinical study. We present a series of 15 patients operated with this technique between October 2014 and September 2019.

Results:

LPFM plasty with autograft quadricipital is a safe technique, which does not use implants, which reduces the risk of complications and restores the anatomy of the extensor apparatus of the knee.

Conclusion:

Our technique of repair of the medial patellofemoral ligament, with quadriceps autograft is a safe, reproducible technique, with good results in the medium term, as well as a low incidence of complications. Patients have returned to their previous sports activities without episodes of re-dislocation.
