Outcomes
Primary outcome [1] 0 0
Patient-reported Outcome: Knee Injury and Osteoarthritis Outcome Score Activities of Daily Living (KOOS ADL) - The Knee injury and Osteoarthritis Outcome Score (KOOS) is a patient self-administered questionnaire that consists of 42 questions and include 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.
Timepoint [1] 0 0
Minimum 2 years (670-1033 days after surgery)
Secondary outcome [1] 0 0
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.

Combination of Patient-reported and Clinical-reported Outcome: Knee Society 2011 - The Knee Society Score is a self-administered questionnaire. The subject completes questions regarding: Symptoms (3 questions), Patient Satisfaction (5 questions), Patient Expectations (3 questions), Functional Activities (5 questions), Standard Activities (6 questions), Advanced Activities (5 questions), and Discretionary Knee Activities ( 4 questions). The surgeon completes questions regarding objective knee indicators. Likert responses are used, typically with five response options.

Summary
Brief summary
The primary objective of this study is to examine the change from pre-operative baseline to
two year postoperative functional performance improvement for the ATTUNE primary, cementless
TKA RP system as measured with the KOOS questionnaire (KOOS-ADL sub-score). This will be
carried out for two configurations: cruciate retaining rotating platform (ATTUNE Cementless
CR RP) and posterior stabilized rotating platform (ATTUNE Cementless PS RP).
