Inclusion

  • Osteoarthritis
  • Primary and secondary traumatic arthritis
  • Avascular necrosis of the femoral condyle
  • Moderate varus, valgus, or flexion deformities (i.e. valgus/varus deformity of less than or equal to 15 degrees, fixed flexion deformity of less than or equal to 10 degrees)
