Besides the control on the form with the date and time of use of analgesics, patients underwent VAS. In all reviews, the range of motion of the knee was also measured with a goniometer; the Lysholm questionnaire was applied in the preoperatory on the day of surgery and on the 15th, 30th and 60th days post-operatively (To avoid bias in the results because of the pain of infiltration, the assessments in the 8th, 15th and 30th days were always made before this procedure).
