Pre-operatively and 4 weeks, 3 months, 6 months and 12 months post-operatively, an evaluation of the current condition of the patient will happen on the basis of standardized questionnaires. Based on the results of these questionnaires, collected at different times, we can determine which treatment provides the best rehabilitation after meniscectomy. The first (preoperative) questionnaire, given at registration of the operation, is completed and given to the nurse of the day hospital on the day of surgery, the other (postoperative) questionnaires are sent electronically to the patient's email address and need to be returned, after filling up.
