Arms

• Active Comparator: Constrained condylar (CCK)
  Once patient meets inclusion criteria, they'll be randomized prior to surgery to a specific CCK implant design. All surgeries will be done at the approved hospital or ASC and if the allocated component isn't used, the patient will still be followed post operatively and remain in the study.
• Active Comparator: Posterior Stabilized (PS) bearing
  Once patient meets inclusion criteria, they'll be randomized prior to surgery to a specific PS implant design. All surgeries will be done at the approved hospital or ASC and if the allocated component isn't used, the patient will still be followed post operatively and remain in the study.
