A Case Report - Treating Chronic Bilateral Patellofemoral Instability with Combined Trocheoplasty and MPFL Reconstruction
Keywords:Trochleoplasty, Trochlear dysplasia, Medial patellafemoral ligament (MPFL) reconstruction, Patellofemoral instability (PFI)
Patients with trochlear dysplasia have recurrent patella-femoral instability (PFI) due to a missing bony guidance for the patella in early flexion. An isolated medial patella-femoral ligament (MPFL) reconstruction can be insufficient, since it mainly addresses instability close to extension. Trochleoplasty has become more popular because of a better knowledge of knee anatomy and biomechanics. When patients are prudently selected and the surgical rationale is carefully followed, very encouraging results are achieved with the application of trochleoplasty with other procedures. Results are more favourable especially in patients with severe trochlear dysplasia and recurrent patellar dislocation, in whom the “benign neglect” of dysplasia and their approach with more “conventional or traditional surgery” would lead to less favourable results. The surgical steps and technical pearls of the procedure are described in this review.
