A comprehensive narrative review of DDH in skeletally mature adolescents and young adults, covering the spectrum of clinical presentation, radiographic diagnosis (with specific measurement thresholds), and the full range of management options from physical therapy to periacetabular osteotomy and proximal femoral correction.
When you see a young active patient with groin pain and a Trendelenburg gait, get a standing AP pelvis and false-profile view before considering arthroscopy — an LCEA <20° or Tönnis angle >10° points to DDH requiring PAO, not just a labral repair.
Arthroscopy alone in the setting of instability-driven DDH risks recurrent pathology and iatrogenic worsening; always assess the proximal femur (cam morphology in 42% of dysplastic hips) as a concomitant source of pathology.
