What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Survivorship of the Device
Time Frame: Preoperative to 1 year, 1 year, 3 years, and 5 years. Survivorship is unavailable at 10 years due to study termination.
|
Survivorship shown in Kaplan Meier survival curves (statistic used to estimate the survival function from lifetime data).
|
Preoperative to 1 year, 1 year, 3 years, and 5 years. Survivorship is unavailable at 10 years due to study termination.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Investigation of Clinical Performance and Patient Outcome With the Knee Society Score (KSS)
Time Frame: Pre-operative, 1, 3, and 5 years. The KSS for 7 and 10 year timepoints are unavailable due to study termination.
|
The Knee Society Clinical Rating System is comprised of two distinct sub-scores: one for pain, range of motion (ROM) and joint stability (Pain/Motion KSS subscale is 0 to 100, with 100 representing a better outcome), and one for functional parameters (Function KSS subscale is 0 to 100, with 100 representing a better outcome).
Sub-scores range from a potential minimum score of 0 to a maximum score of 100 points, and Combined KSS is the summed average of the Pain/Motion and Function sub-scores, leading to a Combined KSS total ranging from 0 to 200 points.
Although the specific scores are not distinguished as "excellent," "good," "fair," or "poor," a higher value represents a better outcome.
|
Pre-operative, 1, 3, and 5 years. The KSS for 7 and 10 year timepoints are unavailable due to study termination.
|
Investigation of Clinical Performance and Patient Outcome With the Knee Injury and Osteoarthritis Outcome Score (KOOS) Patient Questionnaire.
Time Frame: Pre-operative, 1, 3, and 5 years. The KOOS for 7 and 10 year timepoints are unavailable due to study termination.
|
KOOS consists of 5 subscales: Symptoms, Pain, Function in Daily Living, Function in Sport and Recreation, and knee related Quality of Life (QOL).
The previous week is the time period considered when answering the questions.
Standardized answer options are given for each subscale (5 Likert boxes) and each question is assigned a score from 0 to 4. A normalized score is calculated for each subscale, with a minimum of 0 indicating extreme symptoms and a maximum of 100 indicating no symptoms.
Only subscale scores are reported.
|
Pre-operative, 1, 3, and 5 years. The KOOS for 7 and 10 year timepoints are unavailable due to study termination.
|
Investigation of Clinical Performance and Patient Outcome With the EuroQuol-5 Dimension Health Questionnaire (EQ-5D) Patient Questionnaire.
Time Frame: Pre-operative, 1, 3, and 5 years. The EQ-5D for 7 and 10 year timepoints is unavailable due to study termination.
|
The EuroQol-5 Dimension (EQ-5D) is a subject-completed questionnaire designed to assess subject health state values. The EQ-5D consists of 2 areas; EQ-5D descriptive system and the visual analogue scale (VAS). The EQ-5D descriptive system comprises the following five dimensions: mobility self care, usual activities, pain/comfort and anxiety/depression. Each dimension has 3 levels indicating no problems, some problems or extreme problems. The index values on a scale between -1 (low) and 1 (high) are showing the average health status according to the 5 dimensions: A low score shows worse health and a high score shows better health. With the EQ VAS, the respondents can report their perceived health status with a grade ranging from 0 (the worst possible health status) to 100 (the best possible health status). |
Pre-operative, 1, 3, and 5 years. The EQ-5D for 7 and 10 year timepoints is unavailable due to study termination.
