Core Tip
Core tip: Patients with recurrent patella dislocations typically have an insufficiency of the medial patellofemoral ligament (MPFL), which is an additional instability factor in a symptomatic trochlear dysplasia. Following a trochleoplasty, the articulation of the patella is changed to a more medial and dorsal mechanical position. As a consequence, a balanced alignment of the medial soft tissue restraints during a trochleoplasty is very reasonable to achieve an adequate stabilization. The combination of a modified Bereiter trochleoplasty and our MPFL reconstruction technique allowing a simple intra-operative tensioning shows encouraging results.
