结局指标
主要结局
Number of Knees Reported as "Feels Normal" on a Single Assessment Numeric Evaluation (SANE)
时间窗: 12 Months
Participants answered a Single Assessment Numeric Evaluation (SANE) which asked how they rated their knee function. A score of 100 indicates normal and anything below 100 indicates a percentage of normal function.
次要结局
- Number of Knees Reported as "Feels at Least 80% of Normal" on a Single Assessment Numeric Evaluation (SANE)(12 Months)
- Revisions/Removals(3 years)
- Modified Knee Society Score(12 months)
- Number of Knees With Which Participants Reported Being "Happy" or "Very Happy"(12 Months)
