Sit down and make sure that your garment is completely unbuttoned. Lay it across your lap with the inside facing up. Let the sleeve that will go on your affected arm hang between your legs. Start working the sleeve onto this arm with the arm that wasn’t operated on. Just let your affected arm hang down; don’t use it at all. Stand up as you finish using the arm that wasn’t operated on to pull the correct sleeve onto the other arm. Carefully work the sleeve all the way up your arm and onto the shoulder. Grab the rest of the shirt with your unaffected arm. Gently throw the shirt behind you, across your back so that the remaining sleeve ends up near the arm it should go on. Reach up toward the sleeve hole with the arm that wasn’t operated on. Work your arm up through the sleeve until you push your hand through the hole at the end. Use the arm that wasn’t operated on to pull at the garment in whatever areas it isn’t correctly fitted to your body. Then, use the hand of this same arm to pull both sides of your garment together in front of you. Button each button one at a time. If you struggle to button your shirt closed, try grabbing the side without the buttons with your pinky and ring fingers. Use your thumb, pointer finger, and middle finger to grab the other side of the shirt and push the buttons through the holes. When you’re done wearing your shirt, unbutton it with the fingers of your unaffected arm. Take off the sleeve that your unaffected arm is in with your unaffected arm, and toss the shirt across your back toward the arm that underwent surgery. Then, use your unaffected arm to carefully pull the sleeve down off of the other arm.

TL;DR in Indonesian:
Bentangkan baju di paha dan masukkan lengan yang cedera ke lengan baju. Gunakan lengan sehat Anda untuk membetulkan lengan baju di lengan yang cedera. Bawa baju melewati punggung dengan lengan sehat Anda. Masukkan lengan sehat Anda ke lengan baju lainnya. Betulkan baju dan kancing dengan rapat. Lakukan rangkaian langkah di atas secara terbalik untuk melepaskan pakaian.
