SECONDARY outcome

Timeframe: Preoperative (Baseline) and 6, 12, 18, 24, 30, and 36 months postoperatively

Population: The KSS questionnaire assessments were self-reported and not all enrolled subjects completed the questionnaires. See detailed number of participants who completed each response question.

Analysis of KSS from preoperatively (Baseline) up to 36 months postoperatively in 6-months increments to evaluate objective observation, patient satisfaction, and function. Objective knee indicators: Range 0-100 points; Patient Satisfaction: Range 0-40 points; and Functional Activities: Range 0-100 points. Higher scores indicated a better outcome.

SECONDARY outcome

Timeframe: Preoperative (Baseline) and 6, 12, 18, 24, 30, and 36 months postoperatively

Population: The VR-12 questionnaire assessments were self-reported and not all enrolled subjects completed the questionnaires. See detailed number of participants who completed each response question.

Analysis of VR-12 scores preoperatively (Baseline) through 36 months postoperatively in 6 months increments. These scores encompass the individual domains of physical component score (PCS), mental component score (MCS) as well as the sub-domain scores within the PCS (physical functioning, role physical, bodily pain, and general health) and those within the MCS (vitality, social functioning, role emotional, and mental health). Domain Scores: Physical Component Score (PCS): Range 1 to 20 Mental Component Score (MCS): Range 1 to 25 Sub-domain Scores: Physical Functioning: Range 1 to 6 Role Physical: Range 1 to 4 Bodily Pain: Range 1 to 6 General Health: Range 1 to 6 Vitality: Range 1 to 6 Social Functioning: Range 1 to 6 Role Emotional: Range 1 to 4 Mental Health: Range 1 to 10 Transformation of raw scale scores (range 0-100) = {(actual raw score - lowest possible raw score)/possible raw score range} x100 A higher score indicates a better outcome.
