Technology in Knee Replacement Surgery

Several types of total knee replacement systems include:

  • Fixed Bearing – The workhorse of knee replacement surgery
  • Rotating Platform Bearing – closely simulates the action of the normal knee joint
  • Cruciate retaining – designed for knees where the posterior cruciate ligament is retained
  • Posterior stabilized – designed for knees where the posterior cruciate is weak or is removed

Dr. Cuellar will determine the most appropriate knee design based on the individual patient.
