Rate of Return to Sport After Total Knee Prosthesis: Comparison of Three Types of Prostheses

This is an ambispective, comparative study of three cohorts, non-randomized, open, monocentric, relating to the return to sport of patients who have benefited from one of the three designs of prostheses under study (medial pivot, medial bearing and cruciate retaining) after total knee prosthesis. Patients who received a total knee prosthesis with medial pivot, medial bearing and cruciate retaining prosthesis between 2018 and 2020 will be called by the investigator, and the study will be offered to them (D-3 to D0). The investigator will explain the study to the patient, send him the information note electronically and answer all his questions about the study. If the patient agrees to participate after a reflection period, the inclusion (D0) will be documented in the medical file, and the patient will be assessed the same day by telephone using the assessments set up in the study, except for the questionnaires on his functional and physical abilities that will be sent to him electronically. The patient will return his answers to the questionnaires on this same email address or by telephone according to his preference. A secure and unique email address will be created by the principal investigator for the purposes of the study and for use strictly specific to the study, in the investigating center.
