What do we know about Knee Osteoarthritis (KOA) and the Hip Joint?

  • KOA patients demonstrate: (compared with age-matched controls).
  • weakness in the hip joint muscles: quadriceps, hamstrings, and gluteus medius.
  • hyperactive hip adductors and altered hip arthrokinematics.
  • Most KOA studies focus on strengthening the quadriceps muscles rather than the hip abductors.
