This is an observational, prospective study that has the primary goal of validating the Forgotten Joint Score (FJS) as described by Behrend and Giesinger in 2012. Patients will be given two self-assessment questionnaires (WOMAC and FJS) to perform internal consistency analysis, reliability and comparability of results in a population of people undergoing total knee replacement prosthetic surgery.~Comparison of data will be done for each patient by evaluating the evolution of the postoperative period, comparing the results obtained with a well known validated score (WOMAC).~Questionnaires will be given pre-operatively, at 6 month ± 2 weeks, and 12 month ± 1 weeks after surgery.
