Patient Reported Outcome: EuroQol 5D 3L questionnaire (EQ-5D-3L) |
EuroQol 5D 3L questionnaire is a standardized instrument for use as a measure of health outcome that is designed for completion by the subject. |
Pre-op (-90 to -1 days before surgery), <1 year (1 - 303 days), minimum 1 year (304 - 668 days), minimum 2 years (669 - 1763 days), minimum 5 years (1764 - 3588 days), minimum 10 years (3589 - 5413 days), minimum 15 years (5414 - 5658 days). |

Patient-reported Outcome: Oxford Knee Score |
The Oxford Knee Score (OKS) is a patient self-administered 12-item questionnaire with each question having a Likert-lie response option. Each item is scored from 0 to 4, and the items are summated, with lower total scores indicating poorer performance. The OKS measures pain and general activities of daily living. |
Pre-op (-90 to -1 days before surgery), <1 year (1 - 303 days), minimum 1 year (304 - 668 days), minimum 2 years (669 - 1763 days), minimum 5 years (1764 - 3588 days), minimum 10 years (3589 - 5413 days), minimum 15 years (5414 - 5658 days). |

Secondary |
Patient-reported Outcome: Knee Injury and Osteoarthritis Outcome Score (KOOS) |
The Knee injury and Osteoarthritis Outcome Score (KOOS) is a patient self-administered questionnaire that consists of 42 questions and includes the WOMAC Osteoarthritis index. The KOOS consists of 5 subscales; pain, other symptoms, activities of daily living (ADL), sport and recreational function and knee related quality of life. Each question has 5 Likert- like response options. A normalized score (100 indicating no symptoms and 0 indicating extreme symptoms) is calculated for each subscale. |
Pre-op (-90 to -1 days before surgery), <1 year (1 - 303 days), minimum 1 year (304 - 668 days), minimum 2 years (669 - 1763 days), minimum 5 years (1764 - 3588 days), minimum 10 years (3589 - 5413 days), minimum 15 years (5414 - 5658 days). |

Secondary |
Patient-reported Outcome: Pre-surgical/Post-surgical Patient's Knee Implant Performance (PKIP) |
The Pre Surgical and/or Post-surgical Patient's Knee Implant Performance (PKIP) questionnaire is a patient self-administered questionnaire that consists of 25 questions relating to the patient's awareness of their knee. Questions include the patient's self-confidence about the current status of their knee performance, stability, and overall satisfaction. Each question has a 5, 6 or 10 Likert- like response option. |
Pre-op (-90 to -1 days before surgery), <1 year (1 - 303 days), minimum 1 year (304 - 668 days), minimum 2 years (669 - 1763 days), minimum 5 years (1764 - 3588 days), minimum 10 years (3589 - 5413 days), minimum 15 years (5414 - 5658 days). |

Evaluate the impact of surgeon learning curve on clinical and functional outcomes |
A surgeon learning curve will be investigated by comparing learning curve cases (the pooled cohort of each surgeon's first 10 study Subjects) with all investigational Subjects. All primary and secondary outcomes will be compared across the learning curve and post-learning curve Subject cohorts. |

Evaluate changes in femoral component and tibial component alignment |
Radiographs will be reviewed by an independent radiographic reviewer (IRR) in order to minimize bias of radiographic outcomes. Data from the IRR radiographic evaluations will be used to evaluate femoral and tibial component alignment over time. |
