Abstract: Introduction: Patellar instability is a complex condition that may be caused by a variety of factors. This case report discusses a case of recurrent patellar instability due to genu valgum, trochlear dysplasia, and medial patellofemoral ligament (MPFL) tear. Case Report: A 16-year-old boy presented with recurrent patellar instability with a deformity of the right knee for 3 years. Investigations revealed a genu valgum, Dejour type D trochlear dysplasia, and an MPFL tear. He was treated with a medial closing wedge distal femoral osteotomy (DFO), subchondral deepening trochleoplasty, and an MPFL reconstruction as a single procedure. Patient is at 1-year follow-up with good clinical outcomes. Conclusion: Combined trochleoplasty, DFO, and MPFL reconstruction, though technically demanding, provides good results in patients with recurrent patellar instability caused due to a genu valgum and trochlear dysplasia.
