Questionnaire and Radiography for Prosthesis Follow-up

Ever-evolving prosthetic activity as described in a Swedish study that predicts 469 TKA per 10,000 inhabitants in 2130. Increased consultation of controls and post-arthroplasty follow-up is expected. There is a legal obligation to ensure long-term follow-up without official recommendation on follow-up procedures. The objective is to compare a consultation + Xray by the surgeon versus an Xray and a questionnaire completed by the patient who had a knee or hip replacement. This is to demonstrate the equivalence of both. All patients who come back for an annual check of a prosthesis should complete this questionnaire and perform an X-ray of their prosthesis. The study lasts one year and includes all the patients with a previous knee or hip arthroplasty. The result of the questionnaire and Xray will be compared to that of the consultation and Xray.
