Primary | Revision rate | Revision rate of the implant for aseptic loosening. | Up to 5 years of follow-up | |
Secondary | Functional outcomes evaluation such as pain and mobility | Functional ouctomes will be evaluated through the AOFAS score. This score is comprised of nine questions covering three categories: pain (40 points), function (50 points) and alignment (10 points). These are all scored together for a total of 100 points. The higher the score, the better the patient outcome. AOFAS is a clinician reporting tool that required both patient and provider participation to be fully complete. The AOFAS score will be compared to its MCID at each follow-up visit. The MCID will be calculated based on the distribution-based MCID method. | preop, 4-6 weeks postop, 1 year postop, 2 years postop, 5 years postop | |
Secondary | Functional outcomes evaluation such as mobility | Functional ouctomes will be evaluated through the FAAM score. This score is a 29-item questionnaire divided into two subscales: 21-item Activities of Daily Living Subscale and 8-item Sports Subscale. Item score totals, which range from 0 to 84 for the Activities of Daily Living subscale and 0 to 32 for the Sports subscale, are transformed to percentage scores. The higher the score, the better the patient outcomes. It is a self-report outcome instrument. The FAAM score will be compared to its MCID at each follow-up visit. The Minimal Clinically Important Difference (MCID) of the Foot and Ankle Ability Measure (FAAM) at 1 year of follow-up compared to the theorical MCID retrieved in the literature (MCID = 31.2 (sd=25.3, superiority comparison)). For the following follow-up, the MCID will be calculated based on the distribution-based MCID method. | preop, 1 year postop, 2 years postop, 5 years postop | |
Secondary | Functional outcomes evaluation such as mobility | Functional ouctomes will be evaluated through clinical data such as the range of motion. | preop, 4-6 weeks postop, 1 year postop, 2 years postop, 5 years postop | |
Secondary | Health status outcomes evaluation such as pain | Health status outcomes will be evaluated through a visual analogue scale to measure pain. | preop, 4-6 weeks postop, 1 year postop, 2 years postop, 5 years postop | |
Secondary | Health status outcomes evaluation such as quality of life | Health status outcomes will be evaluated through the SF-12 questionnaire to measure the quality of life. It is a self-reported outcome measure, composed of 12 questions. It provides an eight-scale profile of functional health and wellbeing, as well as two psychometrically based physical and mental health summary measures, scored on a T-score metric. The higher the score, the better the patient outcomes. The SF-12 score will be compared to its MCID at each follow-up visit. The MCID will be calculated based on the distribution-based MCID method. | preop, 1 year postop, 2 years postop, 5 years postop | |
Secondary | Radiological data evaluation | Radiological data results such as the postion of the implant, lucency, calcification will be evaluated. | preop, 4-6 weeks postop, 1 year postop, 2 years postop, 5 years postop | |
Secondary | Rate of complications | All complications will be gathered from the intervention up to 5 years of follow-up. | perop, 4-6 weeks postop, 1 year postop, 2 years postop, 5 years postop |
