Knee Society Score (KSS)

Knee Society Score (KSS), a physician- and self-administered questionnaire consisting of several items to measure the outcomes; in this study, the following KOOS scores ranging from 0 to 100 were analyzed: Symptoms Score, Satisfaction Score, Expectation Score, Walking and Standing Score, Standard Activity Score, Advanced Activity Score, Discretionary Activity Score, and Functional Activities Score. Lower KSS scores indicated worse knee conditions.

Time frame: Baseline through last study visit, approximately 8 years

Visual Analogue Scale (VAS)

Visual Analogue Scale (VAS), a self-administered psychometric response instrument to evaluate subject-reported assessment of pain in each knee. There are multiple ways to present VAS scores; in this study, the numerical score ranged from 0 to 100 was used, with the higher score corresponding to the worse pain.

Total Knee Assessment Score

Total Knee Assessment score is a self-administered questionnaire comprising multiple-choice questions regarding subjects' knee-related pain and limitations in ability to work, sports, and other daily living activities. In this study, the numbers and percentages of subjects answering each multiple-choice question were summarized. The higher percentage of subjects giving an answer indicating a higher level of limitations was indicative of worse outcomes.

Knee Injury and Osteoarthritic Outcome Score (KOOS) is a self -administered joint-specific questionnaire comprising questions regarding subject's symptoms, knee stiffness, pain, function and daily living, function and sports and recreational activities, and quality of life; in this study, the following KOOS scores ranging from 0 to 100 (with a score of 0 indicating the worst possible symptoms) were analyzed: Pain Score, Other Symptoms Score, Function in Daily Living Score, Function in Sport and Recreation Score, and Quality of Life Score.

Time frame: Baseline through last study visit, approximately 8 years

Knee Injury and Osteoarthritic Outcome Score Jr (KOOS Jr)

Knee Injury and Osteoarthritic Outcome Score Jr (KOOS Jr) is a shorter self-administered alternative to KOOS focusing on joint pain, stiffness, and daily living and allowing for faster completion by the subject. In this study, the KOOS Interval Score ranging from 0 to 100 was analyzed (with a score of 0 indicating the worst possible symptoms).

Time frame: Baseline through last study visit, approximately 8 years
