Medial Patellofemoral Reconstruction Using Quadriceps Tendon Autograft, Tibial Tubercle Osteotomy, and Sulcus-Deepening Trochleoplasty for Patellar Instability. | LitMetric

AI Article Synopsis

  • * Factors contributing to this risk include tears in the medial patellofemoral ligament, high patella (patella alta), irregularities in the groove where the patella sits (trochlear dysplasia), and increased distance between the tibial tubercle and the trochlear groove.
  • * The article outlines a specific surgical approach that combines MPFL reconstruction using a quadriceps tendon autograft, an open trochleoplasty, and tibial tubercle osteotomy tailored for patients with particular anatomical issues.

Article Abstract

Recurrent patellar dislocations have been correlated with an elevated risk of further patellar dislocations, often requiring surgical treatment. Risk factors include medial patellofemoral ligament (MPFL) tears, patella alta, trochlear dysplasia, and an increased tibial tubercle-trochlear groove distance. Surgical management must be based on a patient's unique joint pathoanatomy and may require MPFL reconstruction with tibial tubercle osteotomy or trochleoplasty either alone or in combination. This article discusses our preferred technique for surgical treatment of recurrent patellar instability with MPFL reconstruction using a quadriceps tendon autograft, an open trochleoplasty, and a tibial tubercle osteotomy for patients with patella alta, trochlear dysplasia, and an increased tibial tubercle-trochlear groove distance.
