[Influencing factors of medial patellofemoral ligament reconstruction for patellar dislocation].

OBJECTIVE

To review the influencing factors of medial patellofemoral ligament (MPFL) reconstruction for patellar dislocation.

METHODS

The literature of MPFL reconstruction for patellar dislocation at home and abroad in recent years were summarized and analyzed.

RESULTS

The influencing factors such as the location of the femoral insertion point, the tension and the fixed angle of the grafts, the dysplasia of the femoral trochlear before operation, the abnormal tuberositas tibiae-trochlear groove value, the high position of the patellar, and the tilting angle of the patellar, are all the factors affecting the effectiveness of MPLF reconstruction.

CONCLUSION

During MPFL reconstruction, the surgical techniques and elimination of other factors that caused patellar instability need to be focused in order to reduce the complications and operation failure.
