No results posted yet for this study

Summary

This study is to evaluate whether the dynamic Medial Patellofemoral Ligament (MPFL) reconstruction as described by Becher is a successful operation technique to prevent patella instability and restore quality of life. It is to assess and compare clinical and functional outcomes of dynamic and static medial patellofemoral ligament reconstruction

Conditions

  • Patellar Instability

Interventions

PROCEDURE

Static reconstruction technique according to Schöttle

In static MPFL reconstruction, a graft (harvested autologous gracilis tendon or allogen transplant) is attached to the femoral and patellar bones using tunnels, screws, and/or anchors.

PROCEDURE

Dynamic reconstruction technique according to Becher

Dynamic MPFL procedure by detaching and reinserting only the distal part of a hamstring muscle to the patella and leaving the proximal tendon attached to its muscle. This way the patella position can be adjusted dynamically by hamstring contraction.
