Patellofemoral cartilage evolution in a 14‐year‐old female patient. Initial magnetic resonance imaging (MRI) showed high‐grade dysplasia and signs of cartilage thinning at the lateral patellar facet (a). Eighteen months after trochleoplasty and MPFL‐R, patellofemoral congruence was improved (b). Follow‐up MRI at 35 months (c) and 112 months (d) showed an intact patellofemoral articular cartilage with no evidence of further degeneration. MPFL‐R, medial patellofemoral ligament reconstruction.
