First‑time dislocation: non-op unless loose bodies/osteochondral fracture or gross instability. Recurrent instability → MPFL reconstruction; address bony factors (TT‑TG distance, trochlear dysplasia, patella alta). Imaging: MRI for MPFL injury/OC defects; CT to measure TT‑TG (>20 mm abnormal). Surgical pearls: Anatomic femoral tunnel at Schöttle point; avoid over‑tightening to prevent medial overload. Rehab: brace, early ROM, VMO strengthening; return to sport after strength and stability restored.
