["To describe individuals' expectations, motivation, and satisfaction before, during, and after rehabilitation for ACL reconstruction and to explore how these factors were associated with return to pre-injury sport activity at 1-year follow-up.", 'Sixty-five individuals (34 males), median age 22 (15-45) years, scheduled for ACL reconstruction participated. Participants completed the International Knee Documentation Committee Subjective Knee Form (IKDC-SKF) and questions about expectations, satisfaction, and motivation pre-operatively and at 16 and 52\xa0weeks after surgery.', 'Prior to surgery, 86\xa0% of participants stated that their goal was to return to their pre-injury sport activity. Those who had returned to their pre-injury sport activity at 52\xa0weeks were more motivated during rehabilitation to return to their pre-injury activity level, more satisfied with their activity level and knee function at 52\xa0weeks, and scored significantly higher on the IKDC-SKF [median 92.0 (range 66.7-100.0)] at 52\xa0weeks, compared to those who had not returned [median 77.6 (range 50.6-97.7)].'] Are psychological factors important to return to pre-injury sport activity after anterior cruciate ligament reconstruction : expect and motivate to satisfy?
