UNASSIGNED: One hundred consecutive patients who underwent simultaneous bilateral TKR were enrolled and received an intraoperative periarticular cocktail injection in the right knee (intervention) and normal saline in the left knee (control). Postoperative pain was recorded using the visual analog scale for each knee, and the time taken to achieve 90° of knee flexion was noted for each side.
UNASSIGNED: The cocktail injected knee had significantly less pain when compared with the control knee during the first 48 hours and significantly shorter period to achieve 90° of knee flexion.
UNASSIGNED: The use of intraoperative periarticular cocktail injection significantly reduces early postoperative pain and provides better early knee motion.
