The recurrent dislocation rate of conservatively treated chronic patellar instability is high, therefore, it is recommended to manage it surgically. A frequently used surgical technique is static medial patellofemoral ligament (MPFL) reconstruction (e.g. Schöttle-technique). A novel dynamic surgical technique according to Becher was developed, addressing the most common complications occurring in static reconstruction, which are malpositioning and overtensioning of the graft. This study is to assess and compare clinical and functional outcomes of dynamic and static medial patellofemoral ligament reconstruction.
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
