  • Any abnormal alignment, function, usage of joint

  • Developmental dysplasia of the hip
  • Femoroacetabular impingement
    • Abnormal contact between the acetabular rim and proximal femur
    • This leads to damage of the acetabular labrum and the acetabular chondrum
  • Slipped capital femoral epiphysis
  • Legg-Calve-Perthes disease
  • Acetabular labral tear
  • Coxa valga
  • Coxa vara
• Prearthritic conditions of the knee
  • Genu valgum
  • Genu varum
• Prearthritic conditions of the foot
  • Flatfoot
  • Hallux valgus
